Investment Risks |

|---|---|
| Brown Advisory Sustainable Value ETF | ETF Risks | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks — The Fund is an ETF and, as a result of this structure, it is exposed to the following risks:
Trading Risk — Shares of the Fund may trade on The NASDAQ Stock Market LLC (the “Exchange”) above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable.
Limited Authorized Participants, Market Makers and Liquidity Providers Risk — Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Brown Advisory Sustainable Value ETF | Equity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Risk — The risk that stock prices will fall over short or extended periods of time, sometimes rapidly and unpredictably. The value of equity securities will fluctuate in response to factors affecting a particular company, as well as broader market and economic conditions. Broad movements in financial markets may adversely affect the price of the Fund’s investments, regardless of how well the companies in which the Fund invests perform. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Moreover, in the event of a company’s bankruptcy, claims of certain creditors, including bondholders, will have priority over claims of common stockholders such as the Fund. |
| Brown Advisory Sustainable Value ETF | Large Capitalization Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Risk — The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
| Brown Advisory Sustainable Value ETF | Value Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value Style Risk — The Adviser’s value investment style may increase the risks of investing in the Fund. If the Adviser’s assessment of market conditions, or a company’s value or prospects for exceeding earnings expectations is inaccurate, the Fund could suffer losses or produce poor performance relative to other funds. In addition, “value stocks” can continue to be undervalued by the market for long periods of time. |
| Brown Advisory Sustainable Value ETF | Sustainable Investing Policy Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sustainable Investing Policy Risk — The Fund’s consideration of sustainability criteria could cause it to make or avoid investments that could result in the Fund underperforming similar funds that do not consider such sustainability criteria. |
| Brown Advisory Sustainable Value ETF | New Fund Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk — Because the Fund is new, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, may not employ a successful investment strategy, or may fail to attract sufficient assets under management to realize economies of scale, any of which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Such liquidation could have negative tax consequences for shareholders and will cause shareholders to incur expenses of liquidation. |
| Brown Advisory Sustainable Value ETF | Management Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk — The Fund is subject to the risk that the Adviser’s judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform in comparison to other funds with similar objectives and investment strategies. |
| Brown Advisory Sustainable Value ETF | Investments in Investment Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investments in Investment Company Risk — When the Fund invests in an investment company, including ETFs, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the investment company’s expenses. Further, while the risks of owning shares of an investment company generally reflect the risks of owning the underlying investments of the investment company, the Fund may be subject to additional or different risks than if the Fund had invested directly in the underlying investments. For example, the lack of liquidity in an ETF could result in its share price being more volatile than that of the underlying portfolio securities. |
| Brown Advisory Sustainable Value ETF | Preferred Stock Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk — Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities. |
| Brown Advisory Sustainable Value ETF | REITs Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REITs Risk — REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. REITs are susceptible to the risks associated with direct ownership of real estate, such as the following: declines in property values; increases in property taxes, operating expenses, interest rates or competition; overbuilding; zoning changes; and losses from casualty or condemnation. REITs typically incur fees that are separate from those of the Fund. Accordingly, the Fund’s investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses. REIT operating expenses are not reflected in the fee table and example in this prospectus. |
| Brown Advisory Sustainable Value ETF | Private Placements Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Private Placements Risk — Investment in privately placed securities may be less liquid than in publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Furthermore, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that might be applicable if their securities were publicly traded. |
| Brown Advisory Sustainable Value ETF | Foreign Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Company Risk — Investing in foreign companies, including direct investments and investments through ADRs, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the same level of regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers and foreign markets and securities may be less liquid. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. While ADRs provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs continue to be subject to many of the risks associated with investing directly in foreign securities. |
| Brown Advisory Sustainable Value ETF | Emerging Markets Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Securities Risk — Investments in emerging markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign securities. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, the securities markets of emerging market countries may consist of companies with smaller market capitalizations and may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. |
| Brown Advisory Sustainable Value ETF | Depositary Receipts Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipts Risk — Investments in depositary receipts, such as ADRs and GDRs, may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. In addition, there is risk involved in investing in unsponsored depositary receipts, as there may be less information available about the underlying issuer than there is about an issuer of sponsored depositary receipts and the prices of unsponsored depositary receipts may be more volatile than those of sponsored depositary receipts. |
| Brown Advisory Sustainable Value ETF | Convertible Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities Risk — The value of a convertible security is influenced by changes in interest rates (with investment value declining as interest rates increase and increasing as interest rates decline) and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature. |
| Brown Advisory Sustainable Value ETF | Shareholder Concentration Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | |
| Brown Advisory Sustainable Value ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | You could lose money by investing in the Fund. |
| Brown Advisory Sustainable Value ETF | Risk Not Insured Depository Institution [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any other government agency. |
| Brown Advisory Sustainable Growth ETF | ETF Risks | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks — The Fund is an ETF and, as a result of this structure, it is exposed to the following risks:
Trading Risk — Shares of the Fund may trade on The NASDAQ Stock Market LLC (the “Exchange”) above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings.

| Brown Advisory Sustainable Growth ETF | Small and Medium Capitalization Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small and Medium Capitalization Companies Risk — The risk that small and medium capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over-the-counter or listed on an exchange. |
| Brown Advisory Sustainable Growth ETF | Growth Investment Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Growth Investment Style Risk — An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer. |

Trading Risk — Shares of the Fund may trade on The NASDAQ Stock Market LLC (the “Exchange”) above or below their NAV.

In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Brown Advisory Flexible Equity ETF | Equity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Risk — The risk that stock prices will fall over short or extended periods of time, sometimes rapidly and unpredictably. The value of equity securities will fluctuate in response to factors affecting a particular company, as well as broader market and economic conditions. Broad movements in financial markets may adversely affect the price of the Fund’s investments, regardless of how well the companies in which the Fund invests perform.

Moreover, in the event of a company’s bankruptcy, claims of certain creditors, including bondholders, will have priority over claims of common stockholders such as the Fund. |

| Risk [Text Block] | Large Capitalization Risk — The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
| Brown Advisory Flexible Equity ETF | Value Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value Style Risk — The Adviser’s value investment style may increase the risks of investing in the Fund. If the Adviser’s assessment of market conditions, or a company’s value or prospects for exceeding earnings expectations is inaccurate, the Fund could suffer losses or produce poor performance relative to other funds. In addition, “value stocks” can continue to be undervalued by the market for long periods of time. |
| Brown Advisory Flexible Equity ETF | New Fund Risk | |

| Brown Advisory Flexible Equity ETF | Investments in Investment Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investments in Investment Company Risk — When the Fund invests in an investment company, including closed—end funds and ETFs, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the investment company’s expenses. Further, while the risks of owning shares of an investment company generally reflect the risks of owning the underlying investments of the investment company, the Fund may be subject to additional or different risks than if the Fund had invested directly in the underlying investments. For example, the lack of liquidity in an ETF could result in its share price being more volatile than that of the underlying portfolio securities. Certain closed—end investment companies issue a fixed number of shares that trade on a stock exchange at a premium or a discount to their net asset value (“NAV”). As a result, a closed—end fund’s share price fluctuates based on what another investor is willing to pay rather than on the market value of the securities in the fund. |
| Brown Advisory Flexible Equity ETF | Preferred Stock Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk — Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time.

In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Democratic Large Cap Core ETF | Large Capitalization Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Risk — The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
| Democratic Large Cap Core ETF | Equity Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk — The risk that stock prices will fall over short or extended periods of time, sometimes rapidly and unpredictably. The value of equity securities will fluctuate in response to factors affecting a particular company, as well as broader market and economic conditions. Broad movements in financial markets may adversely affect the price of the Fund’s investments, regardless of how well the companies in which the Fund invests perform. A variety of factors can lead to volatility in local, regional, or global markets, including regulatory events, inflation, interest rates, government defaults, government shutdowns, war, regional conflicts, acts of terrorism, social unrest, the imposition of tariffs, trade disputes, and substantial economic downturn or recessions. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Moreover, in the event of a company’s bankruptcy, claims of certain creditors, including bondholders, will have priority over claims of common stock holders such as the Fund. |
| Democratic Large Cap Core ETF | Common Stock Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Common Stock Risk — The prices of common stock may fall over short or extended periods of time. Common stock generally is subordinate to preferred stock and debt upon the liquidation or bankruptcy of the issuing company. |
| Democratic Large Cap Core ETF | Sector Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk — The Fund is subject to the following Sector Risk:
Information Technology Sector Risk — The Fund’s investments are exposed to issuers conducting business in the Information Technology Sector. The Information Technology Sector includes companies that offer software and information technology services, manufacturers and distributors of technology hardware and equipment such as communications equipment, cellular phones, computers and peripherals, electronic equipment and related instruments and semiconductors. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Information Technology Sector. The prices of the securities of companies operating in the Information Technology Sector are closely tied to market competition, increased sensitivity to short product cycles and aggressive pricing, and problems with bringing products to market. |
| Democratic Large Cap Core ETF | Issuer-Specific Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer-Specific Risk — Fund performance depends on the performance of individual securities to which the Fund has exposure. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund. |
| Democratic Large Cap Core ETF | Investment Process Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Process Risk — The FEC imposes strict standards regarding the reporting of political contribution data, and violations of such standards may constitute a federal crime. Nevertheless, to the extent that a company fraudulently reports contribution data, such data may cause a company to be included in the Fund’s portfolio when such company otherwise would be excluded absent such fraud. Further, FEC contribution data does not include Excluded Contributions and thus may not reflect all political contributions made by a company, including its senior management. Therefore, the Adviser’s sole reliance on the FEC for political contributions data may cause a company to be included in the Fund’s portfolio that would not qualify for inclusion if the Adviser took into account Excluded Contributions. The Fund’s purchase of such companies’ stocks could negatively affect the value of an investment in the Fund. |
| Democratic Large Cap Core ETF | Active Management Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk — The Fund is subject to the risk that the Adviser’s judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform in comparison to its benchmark index or other funds with similar objectives and investment strategies. |

| First Foundation Fixed Income Fund | Equity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Risk — Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility. |
| First Foundation Fixed Income Fund | Investments in Investment Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investments in Investment Company Risk — When the Fund invests in an investment company, including closed-end funds and ETFs, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the investment company’s expenses. Further, while the risks of owning shares of an investment company generally reflect the risks of owning the underlying investments of the investment company, the Fund may be subject to additional or different risks than if the Fund had invested directly in the underlying investments. For example, the lack of liquidity in an ETF could result in its share price being more volatile than that of the underlying portfolio securities. Certain closed-end investment companies issue a fixed number of shares that trade on a stock exchange at a premium or a discount to their net asset value (“NAV”). As a result, a closed-end fund’s share price fluctuates based on what another investor is willing to pay rather than on the market value of the securities in the fund. |
| First Foundation Fixed Income Fund | Preferred Stock Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk — Preferred stocks are nonvoting equity securities that pay a stated fixed or variable rate of return. Preferred stocks are subject to issuer-specific risks (such as credit risk) and market risks applicable generally to equity securities. The market value of preferred stocks generally decreases when interest rates rise. Preferred stocks generally are subordinated to bonds and other debt instruments in a company’s capital structure in terms of priority to corporate income and liquidation payments and, therefore, will be subject to greater credit risk than the company’s bonds and other debt instruments. Preferred stock may also be subject to prepayment risk, which is discussed below. |
| First Foundation Fixed Income Fund | REITs Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REITs Risk — REITs are pooled investment vehicles that own, and usually operate, income-producing real estate or finance real estate. REITs are susceptible to the risks associated with direct ownership of real estate, as discussed elsewhere in this section. REITs typically incur fees that are separate from those of the Fund. Accordingly, the Fund’s investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses. REIT operating expenses are not reflected in the fee table and example in this prospectus. |
| First Foundation Fixed Income Fund | Credit Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Credit Risk — The risk that the issuer of a security or the counterparty to a contract will default or otherwise become unable to honor a financial obligation. |
| First Foundation Fixed Income Fund | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Interest Rate Risk — The risk that a change in interest rates will cause a fall in the value of fixed income securities, including U.S. Government securities, in which the Fund invests. Generally, the value of the Fund’s fixed income securities will vary inversely with the direction of prevailing interest rates. Changing interest rates may have unpredictable effects on the markets and may affect the value and liquidity of instruments held by the Fund. Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. Interest rate risk may be heightened for investments in emerging market countries. |
| First Foundation Fixed Income Fund | Fixed Income Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed Income Market Risk — The prices of the Fund’s fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. Generally, the Fund’s fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. In the case of foreign securities, price fluctuations will reflect international economic and political events, as well as changes in currency valuations relative to the U.S. dollar. In response to these events, the Fund’s value may fluctuate and/or the Fund may experience increased redemptions from shareholders, which may impact the Fund’s liquidity or force the Fund to sell securities into a declining or illiquid market. |
| First Foundation Fixed Income Fund | Financials Sector Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Financials Sector Risk — The Fund is subject to the risk that the securities of issuers in the Financials Sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Financials Sector. Companies operating in the Financials Sector are subject to extensive government regulation, which may limit the financial commitments they can make and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. |
| First Foundation Fixed Income Fund | Mortgage-Backed Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mortgage-Backed Securities Risk — Mortgage-backed securities are affected significantly by the rate of prepayments and modifications of the mortgage loans backing those securities, as well as by other factors such as borrower defaults, delinquencies, realized or liquidation losses and other shortfalls. Mortgage-backed securities are particularly sensitive to prepayment risk, which is described below, given that the term to maturity for mortgage loans is generally substantially longer than the expected lives of those securities; however, the timing and amount of prepayments cannot be accurately predicted. The timing of changes in the rate of prepayments of the mortgage loans may significantly affect the Fund’s actual yield to maturity on any mortgage-backed securities, even if the average rate of principal payments is consistent with the Fund’s expectation. Along with prepayment risk, mortgage-backed securities are significantly affected by interest rate risk, which is described above. In a low interest rate environment, mortgage loan prepayments would generally be expected to increase due to factors such as refinancings and loan modifications at lower interest rates. In contrast, if prevailing interest rates rise, prepayments of mortgage loans would generally be expected to decline and therefore extend the weighted average lives of mortgage-backed securities held or acquired by the Fund. |
| First Foundation Fixed Income Fund | Asset-Backed Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Asset-Backed Securities Risk — Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities. Securitization trusts generally do not have any assets or sources of funds other than the receivables and related property they own, and asset-backed securities are generally not insured or guaranteed by the related sponsor or any other entity. Asset-backed securities may be more illiquid than more conventional types of fixed-income securities that the Fund may acquire. |
| First Foundation Fixed Income Fund | Below Investment Grade Securities (Junk Bonds) Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Below Investment Grade Securities (Junk Bonds) Risk — Fixed income securities rated below investment grade (junk bonds) involve greater risks of default or downgrade and are generally more volatile than investment grade securities because the prospect for repayment of principal and interest of many of these securities is speculative. Because these securities typically offer a higher rate of return to compensate investors for these risks, they are sometimes referred to as “high yield bonds,” but there is no guarantee that an investment in these securities will result in a high rate of return. |
| First Foundation Fixed Income Fund | Municipal Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Municipal Securities Risk — Municipal securities, like other fixed income securities, rise and fall in value in response to economic and market factors, primarily changes in interest rates, and actual or perceived credit quality. Rising interest rates will generally cause municipal securities to decline in value. Longer-term securities respond more sharply to interest rate changes than do shorter-term securities. A municipal security will also lose value if, due to rating downgrades or other factors, there are concerns about the issuer’s current or future ability to make principal or interest payments. State and local governments rely on taxes and, to some extent, revenues from private projects financed by municipal securities, to pay interest and principal on municipal debt. Poor statewide or local economic results or changing political sentiments may reduce tax revenues and increase the expenses of municipal issuers, making it more difficult for them to meet their obligations. Actual or perceived erosion of the creditworthiness of municipal issuers may reduce the value of the Fund’s holdings. As a result, the Fund will be more susceptible to factors that adversely affect issuers of municipal obligations than a mutual fund that does not have as great a concentration in municipal obligations. |
| First Foundation Fixed Income Fund | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk — The risk that certain securities may be difficult or impossible to sell at the time and price that the Fund would like. The Fund may have to lower the price of the security, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance. Liquidity risk may be heightened in the emerging market countries in which the Fund invests, as a result of their markets being less developed. |
| First Foundation Fixed Income Fund | Counterparty Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk — There is a risk that the Fund may incur a loss arising from the failure of another party to a contract (the counterparty) to meet its obligations. Substantial losses can be incurred if a counterparty fails to deliver on its contractual obligations. |
| First Foundation Fixed Income Fund | Real Estate Sector Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Real Estate Sector Risk — Securities of companies principally engaged in the real estate sector may be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include (i) changes in general economic and market conditions; (ii) changes in the value of real estate properties; (iii) risks related to local economic conditions, overbuilding and increased competition; (iv) increases in property taxes and operating expenses; (v) changes in zoning laws; (vi) casualty and condemnation losses; (vii) variations in rental income, neighborhood values or the appeal of property to tenants; (viii) the availability of financing; and (ix) changes in interest rates and quality of credit extended. |
| First Foundation Fixed Income Fund | Small- and Mid-Capitalization Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small- and Mid-Capitalization Company Risk — The small- and mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, investments in these small- and mid-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small- and mid-cap stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange. |
| First Foundation Fixed Income Fund | Large Capitalization Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Company Risk — The large capitalization companies in which the Fund may invest may lag the performance of smaller capitalization companies because large capitalization companies may experience slower rates of growth than smaller capitalization companies and may not respond as quickly to market changes and opportunities. |
| First Foundation Fixed Income Fund | Prepayment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Prepayment Risk — The risk that, in a declining interest rate environment, fixed income securities with stated interest rates may have the principal paid earlier than expected, requiring the Fund to invest the proceeds at generally lower interest rates. |
| First Foundation Fixed Income Fund | Foreign Investment/Emerging Markets Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment/Emerging Markets Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. In addition, periodic U.S. Government restrictions on investments in issuers from certain non-U.S. countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. |
| First Foundation Fixed Income Fund | Currency Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Risk — As a result of the Fund’s investments in securities or other investments denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund would be adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the United States or abroad. |
| First Foundation Fixed Income Fund | Derivatives Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk — The Fund’s use of futures contracts and options is subject to market risk, leverage risk, correlation risk and liquidity risk. Liquidity risk and market risk are described elsewhere in this section. Leverage risk is the risk that a small percentage of assets invested in derivatives can have a disproportionately larger impact on the Fund’s performance. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. The Fund’s use of derivatives may also increase the amount of taxes payable by shareholders. Both U.S. and non-U.S. regulators have adopted and implemented regulations governing derivatives markets, the ultimate impact of which remains unclear. |
| First Foundation Fixed Income Fund | Cyber Security Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cyber Security Risk — The Fund and its service providers may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. Cyber-attacks may interfere with the processing of shareholder transactions, impact the Fund’s ability to calculate its NAV, cause the release of private shareholder information or confidential company information, impede redemptions, subject the Fund to regulatory fines or financial losses, and cause reputational damage. Similar types of cyber security risks are also present for issuers of securities in which the Fund invests. |
| First Foundation Fixed Income Fund | Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity market as a whole. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Recent examples of events that have led to fluctuations in the equity markets include pandemic risks related to COVID-19 and aggressive measures taken worldwide in response by governments and businesses, elevated inflation levels, problems in the banking sector and wars in Europe and in the Middle East. |

| Risk [Text Block] | Value Style Risk — If the Sub-Adviser’s assessment of market conditions, or a company’s value or prospects for exceeding earnings expectations is wrong, the Fund could suffer losses or produce poor performance relative to other funds. In addition, “value stocks” can continue to be undervalued by the market for long periods of time. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Cyber Security Risk — The Fund and its service providers may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. Cyber-attacks may interfere with the processing of shareholder transactions, impact the Fund’s ability to calculate its NAV, cause the release of private shareholder information or confidential company information, impede redemptions, subject the Fund to regulatory fines or financial losses, and cause reputational damage. Similar types of cyber security risks are also present for issuers of securities in which the Fund invests. |
| First Foundation Total Return Fund | Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity market as a whole. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Recent examples of events that have led to fluctuations in the equity markets include pandemic risks related to COVID-19 and aggressive measures taken worldwide in response by governments and businesses, elevated inflation levels, problems in the banking sector and wars in Europe and in the Middle East. |
| First Foundation Total Return Fund | Asset Allocation Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Asset Allocation Risk — The Fund is subject to asset allocation risk, which is the risk that the Sub-Adviser’s allocation of the Fund’s assets among strategies will cause the Fund to underperform other funds with a similar investment objective and/or underperform the markets in which the Fund invests. |
| First Foundation Total Return Fund | Large Shareholder Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | |
| First Foundation Total Return Fund | Micro-Capitalization Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Micro-Capitalization Company Risk — Micro-capitalization companies may be newly formed or in the early stages of development with limited product lines, markets or financial resources. Therefore, micro-capitalization companies may be less financially secure than large-, mid- and small-capitalization companies and may be more vulnerable to key personnel losses due to reliance on a smaller number of management personnel. In addition, there may be less public information available about these companies. Micro-cap stock prices may be more volatile than large-, mid- and small-capitalization companies and such stocks may be more thinly traded and thus difficult for the Fund to buy and sell in the market. |
| First Foundation Total Return Fund | Communications Sector Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Communications Sector Risk — Communications Sector Risk is the risk that the securities of, or financial instruments tied to the performance of, issuers in the Communications Sector that the Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the Communications Sector (“Communications Companies”), the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Communications Sector. The prices of the securities of Communications Companies may fluctuate widely due to both federal and state regulations governing rates of return and services that may be offered, fierce competition for market share, and competitive challenges in the U.S. from foreign competitors engaged in strategic joint ventures with U.S. companies, and in foreign markets from both U.S. and foreign competitors. In addition, recent industry consolidation trends may lead to increased regulation of Communications Companies in their primary markets. |
| First Foundation Total Return Fund | Growth Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Growth Style Risk — If a growth company does not meet the Sub-Adviser’s expectations that its earnings will increase at a certain rate, the price of its stock may decline significantly, even if it has increased earnings. Many growth companies do not pay dividends. Companies that do not pay dividends often have greater stock price declines during market downturns. Over time, a growth investing style may go in and out of favor, and when out of favor, may cause the Fund to underperform other funds that use differing investing styles. |
| First Foundation Total Return Fund | Hedging Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Risk — Hedging risk is the risk that instruments used for hedging purposes may also limit any potential gain that may result from the increase in value of the hedged asset. To the extent that the Fund engages in hedging strategies, there can be no assurance that such strategy will be effective or that there will be a hedge in place at any given time. |
| First Foundation Total Return Fund | Portfolio Turnover Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk — Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional capital gains tax liabilities, which may affect the Fund’s performance. |
| First Foundation Total Return Fund | Restricted Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Restricted Securities Risk — Investments in restricted securities may be illiquid. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Further, restricted securities may not be subject to the disclosure and other investor protection requirements that might be applicable to unrestricted securities. In order to sell restricted securities, the Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Other transaction costs may be higher for restricted securities than unrestricted securities. |
| First Foundation Total Return Fund | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | You could lose money by investing in the Fund. |
| First Foundation Total Return Fund | Risk Not Insured Depository Institution [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | A Fund share is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. |
| MetLife Opportunistic High Yield Fund | Large Capitalization Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Risk — The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
| MetLife Opportunistic High Yield Fund | Foreign Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Company Risk — Investing in foreign companies poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the U.S. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. |
| MetLife Opportunistic High Yield Fund | Equity Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk — The risk that stock prices will fall over short or extended periods of time. |
| MetLife Opportunistic High Yield Fund | Credit Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Credit Risk — The risk that the issuer of a security or the counterparty to a contract will default or otherwise become unable to honor a financial obligation. |
| MetLife Opportunistic High Yield Fund | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Interest Rate Risk — The risk that a change in interest rates will cause a fall in the value of fixed income securities, including U.S. Government securities, in which the Fund invests. Generally, the value of the Fund’s fixed income securities will vary inversely with the direction of prevailing interest rates. Changing interest rates may have unpredictable effects on the markets and may affect the value and liquidity of instruments held by the Fund. Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. |
| MetLife Opportunistic High Yield Fund | Fixed Income Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed Income Market Risk — The prices of the Fund’s fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. Generally, the value of the Fund’s fixed income securities will vary inversely with the direction of prevailing interest rates. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. In the case of foreign securities, price fluctuations will reflect international economic and political events, as well as changes in currency valuations relative to the U.S. dollar. In response to these events, the Fund’s value may fluctuate and/or the Fund may experience increased redemptions from shareholders, which may impact the Fund’s liquidity or force the Fund to sell securities into a declining or illiquid market. |
| MetLife Opportunistic High Yield Fund | Mortgage-Backed Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mortgage-Backed Securities Risk — Mortgage-backed securities are affected significantly by the rate of prepayments and modifications of the mortgage loans backing those securities, as well as by other factors such as borrower defaults, delinquencies, realized or liquidation losses and other shortfalls. Mortgage-backed securities are particularly sensitive to prepayment risk, which is described below, given that the term to maturity for mortgage loans is generally substantially longer than the expected lives of those securities; however, the timing and amount of prepayments cannot be accurately predicted. The timing of changes in the rate of prepayments of the mortgage loans may significantly affect the Fund’s actual yield to maturity on any mortgage-backed securities, even if the average rate of principal payments is consistent with the Fund’s expectation. Along with prepayment risk, mortgage-backed securities are significantly affected by interest rate risk, which is described above. In a low interest rate environment, mortgage loan prepayments would generally be expected to increase due to factors such as refinancings and loan modifications at lower interest rates. In contrast, if prevailing interest rates rise, prepayments of mortgage loans would generally be expected to decline and therefore extend the weighted average lives of mortgage-backed securities held or acquired by the Fund. |
| MetLife Opportunistic High Yield Fund | Asset-Backed Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Asset-Backed Securities Risk — Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities, and asset-backed securities may not have the benefit of any security interest in the related assets. Securitization trusts generally do not have any assets or sources of funds other than receivables and related property they own, and asset-backed securities are generally not insured or guaranteed by the related sponsor or any other entity. Asset-backed securities may be more illiquid than more conventional types of fixed income securities that the Fund may acquire. |
| MetLife Opportunistic High Yield Fund | Municipal Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Municipal Securities Risk — Municipal securities, like other fixed income securities, rise and fall in value in response to economic and market factors, primarily changes in interest rates, and actual or perceived credit quality. Rising interest rates will generally cause municipal securities to decline in value. Longer-term securities respond more sharply to interest rate changes than do shorter-term securities. A municipal security will also lose value if, due to rating downgrades or other factors, there are concerns about the issuer’s current or future ability to make principal or interest payments. State and local governments rely on taxes and, to some extent, revenues from private projects financed by municipal securities, to pay interest and principal on municipal debt. Poor statewide or local economic results or changing political sentiments may reduce tax revenues and increase the expenses of municipal issuers, making it more difficult for them to meet their obligations. Actual or perceived erosion of the creditworthiness of municipal issuers may reduce the value of the Fund’s holdings. As a result, the Fund will be more susceptible to factors that adversely affect issuers of municipal obligations than a mutual fund that does not have as great a concentration in municipal obligations. |
| MetLife Opportunistic High Yield Fund | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk — The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower the price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance. |
| MetLife Opportunistic High Yield Fund | Prepayment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Prepayment Risk — The risk that, in a declining interest rate environment, fixed income securities with stated interest rates may have the principal paid earlier than expected. Such sooner-than-expected principal payments may reduce the returns of the Fund because of loss of expected future interest payments on the principal amount paid back early and requires the Fund to invest the proceeds at generally lower interest rates. |
| MetLife Opportunistic High Yield Fund | Derivatives Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk — The Fund may use of futures contracts which are subject to market risk, leverage risk, liquidity risk, credit risk and valuation risk and are described elsewhere in this section. There also is risk of correlation in that the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. The other parties to certain derivative contracts present the same types of credit risk as issuers of fixed income securities. The Fund’s use of derivatives may also increase the amount of taxes payable by shareholders. Both U.S. and non-U.S. regulators have adopted and implemented regulations governing derivatives markets, the ultimate impact of which remains unclear. |
| MetLife Opportunistic High Yield Fund | Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk — The risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. From time to time, certain investments held by the Fund may have limited marketability and may be difficult to value and sell at favorable times or prices. Markets for securities in which the Fund invests may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. In addition, extraordinary events outside the control of the Fund, including acts of God (e.g., fire, flood, earthquake, storm, hurricane or other natural disaster), acts of war (e.g., war, invasion, acts of foreign enemies, hostilities, insurrection, or terrorist activities, whether war is declared or not) and global health events, such as epidemics, pandemics and disease, and their related social and economic impacts, may cause significant adverse market conditions and result in losses in value to the Fund’s investments. Such events may initially negatively affect a particular industry, sector, country or region and may spread quickly or unpredictably to negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Adverse market conditions may be prolonged and may adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. |
| MetLife Opportunistic High Yield Fund | Portfolio Turnover Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk — The Fund may buy and sell securities frequently. Such a strategy often involves higher expenses, including brokerage commissions, and may increase the amount of capital gains (in particular, short term gains) realized by the Fund. Shareholders may pay tax on such capital gains and will indirectly incur additional expenses related to a fund with a higher portfolio turnover rate. |
| MetLife Opportunistic High Yield Fund | High Yield or Below Investment Grade Securities Junk Bonds Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | High Yield or Below Investment Grade Securities (Junk Bonds) Risk — High yield or “junk” bonds involve greater risks of default or downgrade and are more volatile than investment grade securities because the prospect for repayment of principal and interest of many of these securities is speculative. Because these bonds typically offer a higher rate of return to compensate investors for these risks, they are referred to as “high yield bonds,” but there is no guarantee that an investment in these securities will result in a high rate of return. These bonds also may be less liquid than higher quality investments. |
| MetLife Opportunistic High Yield Fund | Unrated Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Unrated Securities Risk — Debt securities that are not rated by Moody’s, S&P or Fitch may not have an active trading market or may be difficult to value, which means the Fund might have difficulty selling them promptly at an acceptable price. |
| MetLife Opportunistic High Yield Fund | Investment Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Style Risk — The risk that high yield fixed income securities may underperform other segments of the fixed income markets or the fixed income markets as a whole. |
| MetLife Opportunistic High Yield Fund | Investment Strategy Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Strategy Risk — The risk that the Fund’s investment strategy may underperform other segments of the below investment grade bond markets or the bond markets as a whole. |
| MetLife Opportunistic High Yield Fund | Corporate Fixed Income Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Corporate Fixed Income Securities Risk — Corporate fixed income securities respond to economic developments, especially changes in interest rates, as well as perceptions of the creditworthiness and business prospects of individual issuers. |
| MetLife Opportunistic High Yield Fund | Bank Loans Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Bank Loans Risk — The Fund may invest in bank loans through participations or assignments. Investments in bank loans (through both assignments and participations) are generally subject to the same risks as investments in other types of debt instruments, including, in many cases, investments in junk bonds. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not benefit directly from any collateral supporting the loan in which they have purchased the participation. As a result, the Fund will assume the credit risk of both the borrower and the lender that is selling the participation. When the Fund purchases assignments from lenders the Fund will acquire direct rights against the borrower on the loan. The Fund may have difficulty disposing of bank loans because, in certain cases, the market for such instruments is not highly liquid. The lack of a highly liquid secondary market may have an adverse impact on the value of such instruments and on the Fund’s ability to dispose of the bank loan in response to a specific economic event, such as deterioration in the creditworthiness of the borrower, which may cause the Fund to be unable to realize the full value of its investment in a bank loan. There may be limited public information available regarding bank loans and bank loans may be difficult to value. If the Fund holds a bank loan through another financial institution, or relies on a financial institution to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution. It is possible that any collateral securing a loan may be insufficient or unavailable to the Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Bank loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. |
| MetLife Opportunistic High Yield Fund | Call Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Call Risk — The risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). If an issuer calls a security that the Fund has invested in, the Fund may not recoup the full amount of its initial investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features. |
| MetLife Opportunistic High Yield Fund | Duration Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Duration Risk — The longer-term securities in which the Fund may invest tend to be more volatile than shorter-term securities. A portfolio with a longer average portfolio duration is more sensitive to changes in interest rates than a portfolio with a shorter average portfolio duration. |
| MetLife Opportunistic High Yield Fund | Extension Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Extension Risk — The risk that rising interest rates may extend the duration of a fixed income security, typically reducing the security’s value. |
| MetLife Opportunistic High Yield Fund | Valuation Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk — The risk that a security may be difficult to value. The Fund may value certain securities at a price higher than the price at which they can be sold. |
| MetLife Opportunistic High Yield Fund | Exchange-Traded Funds ETFs Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Exchange-Traded Funds (ETFs) Risk — The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities in which the ETF invests, although lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio securities. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. |
| MetLife Opportunistic High Yield Fund | Money Market Instruments Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Money Market Instruments Risk — The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. A money market fund’s sponsor has no legal obligation to provide financial support to the fund, and there should be no expectation that the sponsor will provide financial support to the fund at any time. Certain money market funds float their net asset value while others seek to preserve the value of investments at a stable net asset value (typically, $1.00 per share). An investment in a money market fund, even an investment in a fund seeking to maintain a stable net asset value per share, is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds. Under certain circumstances where a money market fund experiences heightened redemptions, it may be required to impose a mandatory liquidity fee on amounts the Fund redeems from the money market fund (i.e., impose a liquidity fee). In addition, a money market fund may impose a liquidity fee of up to 2% on amounts the Fund redeems from the money market fund during circumstances where the money market fund’s board of directors determines such fee would be in the money market fund’s best interests. These measures may result in an investment loss. Money market funds and the securities they invest in are subject to comprehensive regulations. The regulations governing money market funds were recently amended in July, 2023, and their implementation and interpretation, as well as enforcement, may affect the manner of operation, performance and/or yield of money market funds. |
| MetLife Opportunistic High Yield Fund | Leverage Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leverage Risk — The Fund’s use when-issued, delayed delivery or forward commitment transactions may result in the Fund’s total investment exposure substantially exceeding the value of its portfolio securities and, in certain cases, the Fund’s investment returns depending substantially on the performance of securities that the Fund may not directly own. The use of leverage can amplify the effects of market volatility on the Fund’s share price and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. In the case of borrowings, the Fund may experience losses if its borrowing costs exceed the investment returns on the securities purchased with the borrowed money. The Fund’s use of leverage may result in a heightened risk of investment loss. |
| MetLife Opportunistic High Yield Fund | Convertible Securities and Preferred Stocks Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities and Preferred Stocks Risk — Convertible and preferred securities have many of the same characteristics as stocks, including many of the same risks. In addition, convertible securities may be more sensitive to changes in interest rates than stocks. Convertible securities may also have credit ratings below investment grade, meaning that they carry a higher risk of failure by the issuer to pay principal and/or interest when due. |
| MetLife Opportunistic High Yield Fund | Warrants and Rights Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Warrants and Rights Risk —Warrants and rights may be more speculative than other types of investments. The price of a warrant or right may be more volatile than the price of its underlying security, and a warrant or right may offer greater potential for capital appreciation as well as capital loss. A warrant or right ceases to have value if it is not exercised prior to its expiration date. |
| MetLife Opportunistic High Yield Fund | When-Issued and Delayed Delivery Securities and Forward Commitments Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | When-Issued and Delayed Delivery Securities and Forward Commitments Risk — When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. |
| MetLife Opportunistic High Yield Fund | Privately Issued Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Privately Issued Securities Risk — Investment in privately placed securities may be less liquid than in publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Further, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that might be applicable if their securities were publicly traded. |
| MetLife Opportunistic High Yield Fund | U.S. Government Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Government Securities Risk — Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency’s own resources. |
| MetLife Opportunistic High Yield Fund | Small- and Mid-Capitalization Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small- and Mid-Capitalization Companies Risk — Small- and mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small- and mid-capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small- and mid-capitalization stocks may be more volatile than those of larger companies. Small- and mid-capitalization stocks may be traded over-the-counter or listed on an exchange. |
| MetLife Opportunistic High Yield Fund | Master Limited Partnerships MLPs Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Master Limited Partnerships (MLPs) Risk — MLPs are limited partnerships in which the ownership units are publicly traded. MLPs often own several properties or businesses (or own interests) that are related to oil and gas industries or other natural resources, but they also may finance other projects. To the extent that an MLP’s interests are all in a particular industry, the MLP will be negatively impacted by economic events adversely impacting that industry. Additional risks of investing in a MLP also include those involved in investing in a partnership as opposed to a corporation, such as limited control of management, limited voting rights and tax risks. MLPs may be subject to state taxation in certain jurisdictions, which will have the effect of reducing the amount of income paid by the MLP to its investors. |
| MetLife Opportunistic High Yield Fund | Large Purchase and Redemption Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Purchase and Redemption Risk — Large purchases or redemptions of the Fund’s shares may force the Fund to purchase or sell securities at times when it would not otherwise do so, and may cause the Fund’s portfolio turnover rate and transaction costs to rise, which may negatively affect the Fund’s performance and have adverse tax consequences for Fund shareholders. |

| Risk [Text Block] | Market Risk — The risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. From time to time, certain investments held by the Fund may have limited marketability and may be difficult to value and sell at favorable times or prices. Markets for securities in which the Fund invests may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. In addition, extraordinary events outside the control of the Fund, including acts of God (e.g., fire, flood, earthquake, storm, hurricane or other natural disaster), acts of war (e.g., war, invasion, acts of foreign enemies, hostilities, insurrection, or terrorist activities, whether war is declared or not) and global health events, such as epidemics, pandemics and disease, and their related social and economic impacts, may cause significant adverse market conditions and result in losses in value to the Fund’s investments. Such events may initially negatively affect a particular industry, sector, country or region and may spread quickly or unpredictably to negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Adverse market conditions may be prolonged and may adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. |
| MetLife Small Company Equity Fund | Portfolio Turnover Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk — The Fund may buy and sell securities frequently. Such a strategy often involves higher expenses, including brokerage commissions, and may increase the amount of capital gains (in particular, short term gains) realized by the Fund. Shareholders may pay tax on such capital gains and will indirectly incur additional expenses related to a fund with a higher portfolio turnover rate. |
| MetLife Small Company Equity Fund | Investment Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Style Risk — Relative value investing focuses on companies with stocks that appear undervalued in light of factors such as the company’s earnings, book value, revenues or cash flow. If the Adviser’s assessment of market conditions, or a company’s value or prospects for exceeding earnings expectations, is wrong, the Fund could suffer losses or produce poor performance relative to other funds. |
| MetLife Small Company Equity Fund | Investment Strategy Risk | |
| Prospectus [Line Items] | |

| MetLife Small Company Equity Fund | Exchange-Traded Funds ETFs Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Exchange-Traded Funds (ETFs) Risk — The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities in which the ETF invests, although lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio securities. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. |
| MetLife Small Company Equity Fund | Money Market Instruments Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Money Market Instruments Risk — The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. A money market fund’s sponsor has no legal obligation to provide financial support to the fund, and there should be no expectation that the sponsor will provide financial support to the fund at any time. Certain money market funds float their net asset value while others seek to preserve the value of investments at a stable net asset value (typically, $1.00 per share). An investment in a money market fund, even an investment in a fund seeking to maintain a stable net asset value per share, is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds. Under certain circumstances where a money market fund experiences heightened redemptions, it may be required to impose a mandatory liquidity fee on amounts the Fund redeems from the money market fund (i.e., impose a liquidity fee). In addition, a money market fund may impose a liquidity fee of up to 2% on amounts the Fund redeems from the money market fund during circumstances where the money market fund’s board of directors determines such fee would be in the money market fund’s best interests. These measures may result in an investment loss. Money market funds and the securities they invest in are subject to comprehensive regulations. The regulations governing money market funds were recently amended in July, 2023, and their implementation and interpretation, as well as enforcement, may affect the manner of operation, performance and/or yield of money market funds. |
| MetLife Small Company Equity Fund | Large Purchase and Redemption Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Purchase and Redemption Risk — Large purchases or redemptions of the Fund’s shares may force the Fund to purchase or sell securities at times when it would not otherwise do so, and may cause the Fund’s portfolio turnover rate and transaction costs to rise, which may negatively affect the Fund’s performance and have adverse tax consequences for Fund shareholders. |
| MetLife Small Company Equity Fund | Small Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small Companies Risk — Small companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, stocks of small companies may be more volatile than those of larger companies. Stocks of small companies may be traded over-the-counter or listed on an exchange. |
| MetLife Small Company Equity Fund | Sector Emphasis Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Emphasis Risk — The securities of companies in the same business sector, if comprising a significant portion of the Fund’s portfolio, may in some circumstances react negatively to market conditions, interest rates and economic, regulatory or financial developments and adversely affect the value of the portfolio to a greater extent than if such securities comprised a lesser portion of the Fund’s portfolio or the Fund’s portfolio was diversified across a greater number of industry sectors. |

| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | REITs Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REITs Risk — REITs are trusts that invest primarily in commercial real estate or real estate-related loans. The Fund’s investments in REITs will be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions. Some REITs may have limited diversification and may be subject to risks inherent in financing a limited number of properties. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Depositary Receipts Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipts Risk — Depositary receipts, such as ADRs, are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Convertible Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities Risk — The value of a convertible security is influenced by changes in interest rates (with investment value declining as interest rates increase and increasing as interest rates decline) and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Equity Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk — The Fund invests in equity securities and is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk — The risk that certain securities may be difficult or impossible to sell at the time and the price that the seller would like. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Foreign Investment/Emerging Markets Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment/Emerging Markets Risk — The risk that non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. Emerging market countries are countries that major international financial institutions, such as the International Monetary Fund or the World Bank, generally consider to be less economically mature than developed nations. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Currency Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Risk — As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case the dollar value of an investment in the Fund would be adversely affected. Currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the United States or abroad. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Growth Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Growth Style Risk — The Adviser’s growth investment style may increase the risks of investing in the Fund. Because the prices of growth stocks are based largely on the expectation of future earnings, growth stock prices can decline rapidly and significantly when it appears that those expectations will not be met. In addition, a growth investing style may go in and out of favor over time, causing the Fund to sometimes underperform other equity funds that use differing investing styles. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Portfolio Turnover Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk — The Fund is subject to portfolio turnover risk because it may buy and sell investments frequently. Such a strategy often involves higher expenses, including brokerage commissions, and may increase the amount of capital gains (in particular, short-term gains) realized by the Fund. Shareholders may be required to pay tax on such capital gains. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Sector Emphasis Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Emphasis Risk — The securities of companies in the same business sector, if comprising a significant portion of the Fund’s portfolio, may in some circumstances react negatively to market conditions, interest rates and economic, regulatory or financial developments and adversely affect the value of the portfolio to a greater extent than if such securities comprised a lesser portion of the Fund’s portfolio or the Fund’s portfolio was diversified across a greater number of industry sectors. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | Small Capitalization Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small Capitalization Companies Risk — Small capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization stocks may be more volatile than those of larger companies. Small capitalization stocks may be traded over-the-counter or listed on an exchange. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | IPO Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | IPO Risk — The market value of shares issued in an IPO may fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about a company’s business model, quality of management, earnings growth potential, and other criteria used to evaluate its investment prospects. Accordingly, investments in IPO shares involve greater risks than investments in shares of companies that have traded publicly on an exchange for extended periods of time. Investments in IPO shares may also involve high transaction costs, and are subject to market risk and liquidity risk, which are described elsewhere in this section. |
| NICHOLAS PARTNERS SMALL CAP GROWTH FUND | ETFs Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETFs Risk — The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, although lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio securities. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. |

| Rayliant Wilshire NxtGen US Large Cap Equity ETF | ETF Risks | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks – The Fund is an exchange-traded fund (“ETF”) and, as a result of this structure, it is exposed to the following risks:
Limited Authorized Participants, Market Makers and Liquidity Providers Risk – Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Cash Transactions Risk – Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to “Authorized Participants.” Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds at least partially in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.
Index-Related Risk – Errors in index data, index computations and/or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Errors in respect of the quality, accuracy and completeness of the data used to compile the Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Such errors may negatively or positively impact the Fund and its shareholders. For example, during a period where the Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Index’s other constituents. Shareholders should understand that any gains from Index Provider errors will be kept by the Fund and its shareholders and any losses or costs resulting from Index Provider errors will be borne by the Fund and its shareholders.
Tracking Error Risk – While the Fund seeks to replicate the performance of the Index, the Fund’s return may not precisely match the return of the Index. Tracking error may result from, among other things, imperfect correlation between the Fund’s holdings and those of the Index, pricing differences, changes to the Index, regulatory restrictions, legal restrictions, liquidity concerns, transaction costs, operational considerations or timing of cash flows into and out of the Fund.
Trading Risk – Shares of the Fund may trade on NYSE Arca, Inc. (the “Exchange”) above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Fund’s shares will fluctuate continuously throughout trading hours based on market supply and demand and may deviate significantly from the value of the Fund’s holdings, particularly in times of market stress, with the result that investors may pay more or receive less than the underlying value of the Fund shares bought or sold. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. In stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings.
Passive Strategy Risk – The Fund is not actively managed. Rather, the Fund attempts to track the performance of an unmanaged index of securities. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund will hold constituent securities of the Index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy.
Quantitative Investing Risk – The Index is constructed by the Index Provider using a rules-based methodology based on quantitative machine learning models developed by Rayliant. Securities selected according to a quantitative model can perform differently from the market as a whole based on the factors used in the model, the weight placed on each factor and changes from the factors’ historical trends. Due to the significant role technology plays in a quantitative model, use of a quantitative model carries the risk of potential issues with the design, coding, implementation or maintenance of the computer programs, data and/or other technology used in the quantitative model. These issues could lead to the selection of assets for inclusion in the Index that produce inferior investment returns or provide exposure to greater risk of loss. As a result, the Fund’s performance may be lower or the Fund may be subject to greater risk than if the Index had not been constructed using quantitative modeling because the Fund invests a substantial portion of its assets in the component securities of the Index. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Large Capitalization Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Risk – The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. Large-capitalization stocks may underperform the broader market, mid-capitalization stocks, or small-capitalization stocks for extended periods. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | REITs Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REITs Risk – REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. REITs are susceptible to the risks associated with direct ownership of real estate, such as the following: declines in property values; increases in property taxes, operating expenses, interest rates or competition; overbuilding; zoning changes; and losses from casualty or condemnation. REITs typically incur fees that are separate from those of the Fund. Accordingly, the Fund’s investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses. REIT operating expenses are not reflected in the fee table and example in this prospectus. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Equity Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk – The risk that stock prices will fall over short or extended periods of time, sometimes rapidly and unpredictably. The value of equity securities will fluctuate in response to factors affecting a particular company, as well as broader market and economic conditions. Broad movements in financial markets may adversely affect the price of the Fund’s investments, regardless of how well the companies in which the Fund invests perform. A variety of factors can lead to volatility in local, regional, or global markets, including regulatory events, inflation, interest rates, government defaults, government shutdowns, war, regional conflicts, acts of terrorism, social unrest, the imposition of tariffs, trade disputes, and substantial economic downturn or recessions. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Moreover, in the event of a company’s bankruptcy, claims of certain creditors, including bondholders, will have priority over claims of common stock holders such as the Fund. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk – The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to lower the price of the security, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Derivatives Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk – Investments in swaps are subject to market risk, leverage risk, correlation risk, and liquidity risk. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. Leverage risk is the risk that since derivatives may be purchased for a fraction of their value, a relatively small price movement in a derivative may result in an immediate and substantial loss or gain for the Fund, and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly or at all with the underlying asset, rate or index. Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund’s use of swaps is also subject to credit risk and valuation risk. Credit risk is the risk that the counterparty to a derivative contract will default or otherwise become unable to honor a financial obligation. Valuation risk is the risk that a security may be difficult to value. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Portfolio Turnover Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk – Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional capital gains tax liabilities, which may affect the Fund’s performance. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Valuation Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk – The risk that a security may be difficult to value. The Fund may value certain securities at a price higher than the price at which they can be sold. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Machine Learning Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Machine Learning Risk – The Index tracked by the Fund uses machine-learning and quantitative models to determine its constituent securities and weightings. As a result, the Fund is subject to the following risks: |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Machine Learning and Quantitative Index Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Machine Learning and Quantitative Index Risk – The machine-learning and quantitative models used by the Index rely on historical financial, fundamental, and market data and statistical assumptions that may not perform as intended in all market conditions. If the models or assumptions used by the Index do not accurately forecast future market behavior, the Index and the Fund may underperform other investment strategies or market benchmarks. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Data Quality and Model Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Data Quality and Model Risk – The machine-learning models used in the Index methodology depend on the accuracy, completeness, and relevance of historical data. If the data used by the Index contains errors, omissions, or biases, or becomes outdated or less relevant, the Index’s construction and performance may be adversely affected. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Market Regime Change Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Regime Change Risk – Machine-learning models are developed using historical data and may be less effective during periods of significant market disruption, unusual volatility, or structural changes in markets. In such environments, the Index methodology may not adapt quickly or effectively, which could result in unexpected or unfavorable Index performance. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Index Methodology and Calculation Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Methodology and Calculation Risk – The Index relies on the systematic application of quantitative and machine-learning models. Errors in the design, calculation, or ongoing maintenance of the Index, including operational or technological errors, could cause the Index to be calculated incorrectly or differ from its intended methodology, which could negatively affect the Fund. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Cybersecurity and Technology Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity and Technology Risk – The Index methodology relies on complex computer systems and technology. Cybersecurity incidents, system failures, or other technological disruptions affecting the Index provider or other third-party service providers could interfere with the calculation or dissemination of the Index and adversely impact the Fund. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Geographic Focus Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Focus Risk – Because the Fund focuses its investments in the U.S., the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within the U.S. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments. |
| Rayliant Wilshire NxtGen US Large Cap Equity ETF | Sector Focus Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Focus Risk – Because the Index, and thus the Fund, may, from time to time, be more heavily invested in particular sectors, the value of its shares may be especially sensitive to factors and economic risks that specifically affect those sectors. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors. The Fund’s sector exposures may change over time as the composition of the Index changes over time.
Digital Information and Services Sector Risk – The Fund’s investments are exposed to issuers conducting business in the Digital Information and Services sector. The digital information and services sector includes companies involved in cloud computing, digital media, data analytics, online platforms, and related technologies. These companies are subject to rapid technological change, intense competition, and evolving regulatory environments, including data privacy, cybersecurity, and content moderation laws. They may also face heightened risks related to intellectual property, reliance on third-party infrastructure or digital platforms, and changes in consumer preferences. Additionally, security breaches, system failures, or regulatory investigations could materially affect their business operations and valuations. As a result, investments in this sector may exhibit higher volatility and carry a greater risk of loss compared to investments spread across a broader range of sectors.
Technology Sector Risk – The Fund’s investments are exposed to issuers conducting business in the Technology sector. Securities of technology companies may be subject to greater price volatility than securities of companies in other sectors. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities also may be affected adversely by changes in technology, consumer and business purchasing patterns, government regulation and/or obsolete products or services. |

These issues could lead to the selection of assets for inclusion in the Index that produce inferior investment returns or provide exposure to greater risk of loss. As a result, the Fund’s performance may be lower or the Fund may be subject to greater risk than if the Index had not been constructed using quantitative modeling because the Fund invests a substantial portion of its assets in the component securities of the Index. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Preferred Stock Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk – Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Foreign Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Company Risk – Investing in foreign companies, including direct investments and investments through ADRs, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the same level of regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers and foreign markets and securities may be less liquid. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. While ADRs provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs continue to be subject to many of the risks associated with investing directly in foreign securities. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Emerging Markets Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Securities Risk – Investments in emerging markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign securities. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, the securities markets of emerging market countries may consist of companies with smaller market capitalizations and may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Small and Medium Capitalization Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small and Medium Capitalization Companies Risk – The risk that small and medium capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over-the-counter or listed on an exchange. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Equity Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk – The risk that stock prices will fall over short or extended periods of time, sometimes rapidly and unpredictably. The value of equity securities will fluctuate in response to factors affecting a particular company, as well as broader market and economic conditions. Broad movements in financial markets may adversely affect the price of the Fund’s investments, regardless of how well the companies in which the Fund invests perform. A variety of factors can lead to volatility in local, regional, or global markets, including regulatory events, inflation, interest rates, government defaults, government shutdowns, war, regional conflicts, acts of terrorism, social unrest, the imposition of tariffs, trade disputes, and substantial economic downturn or recessions. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Moreover, in the event of a company’s bankruptcy, claims of certain creditors, including bondholders, will have priority over claims of common stock holders such as the Fund. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk – The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to lower the price of the security, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Derivatives Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk – Investments in swaps are subject to market risk, leverage risk, correlation risk, and liquidity risk. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. Leverage risk is the risk that since derivatives may be purchased for a fraction of their value, a relatively small price movement in a derivative may result in an immediate and substantial loss or gain for the Fund, and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly or at all with the underlying asset, rate or index. Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund’s use of swaps is also subject to credit risk and valuation risk. Credit risk is the risk that the counterparty to a derivative contract will default or otherwise become unable to honor a financial obligation. Valuation risk is the risk that a security may be difficult to value. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Portfolio Turnover Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk – Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional capital gains tax liabilities, which may affect the Fund’s performance. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Valuation Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk – The risk that a security may be difficult to value. The Fund may value certain securities at a price higher than the price at which they can be sold. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Machine Learning Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Machine Learning Risk – The Index tracked by the Fund uses machine-learning and quantitative models to determine its constituent securities and weightings. As a result, the Fund is subject to the following risks:
Machine Learning and Quantitative Index Risk – The machine-learning and quantitative models used by the Index rely on historical financial, fundamental, and market data and statistical assumptions that may not perform as intended in all market conditions. If the models or assumptions used by the Index do not accurately forecast future market behavior, the Index and the Fund may underperform other investment strategies or market benchmarks.
Data Quality and Model Risk – The machine-learning models used in the Index methodology depend on the accuracy, completeness, and relevance of historical data. If the data used by the Index contains errors, omissions, or biases, or becomes outdated or less relevant, the Index’s construction and performance may be adversely affected.
Market Regime Change Risk – Machine-learning models are developed using historical data and may be less effective during periods of significant market disruption, unusual volatility, or structural changes in markets. In such environments, the Index methodology may not adapt quickly or effectively, which could result in unexpected or unfavorable Index performance.
Index Methodology and Calculation Risk – The Index relies on the systematic application of quantitative and machine-learning models. Errors in the design, calculation, or ongoing maintenance of the Index, including operational or technological errors, could cause the Index to be calculated incorrectly or differ from its intended methodology, which could negatively affect the Fund.
Cybersecurity and Technology Risk – The Index methodology relies on complex computer systems and technology. Cybersecurity incidents, system failures, or other technological disruptions affecting the Index provider or other third-party service providers could interfere with the calculation or dissemination of the Index and adversely impact the Fund. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Geographic Focus Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Focus Risk – To the extent that it focuses its investments in a particular country or geographic region, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within that country or geographic region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Sector Focus Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Focus Risk – Because the Fund may, from time to time, be more heavily invested in particular sectors, the value of its shares may be especially sensitive to factors and economic risks that specifically affect those sectors. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors. The Fund’s sector exposures may change over time, as macroeconomic, market, sector and company-specific conditions change.
Financials Sector Risk – The Fund’s investments are exposed to issuers conducting business in the Financials sector. Performance of companies in the Financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. The impact of more stringent capital requirements, recent or future regulation of any individual financial company, or recent or future regulation of the financials sector as a whole cannot be predicted. In recent years, cyber attacks and technology malfunctions have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.
Technology Sector Risk – The Fund’s investments are exposed to issuers conducting business in the Technology sector. Securities of technology companies may be subject to greater price volatility than securities of companies in other sectors. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology securities also may be affected adversely by changes in technology, consumer and business purchasing patterns, government regulation and/or obsolete products or services. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Risk of Investing in China | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Investing in China – The Chinese economy is generally considered an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. China may be subject to considerable degrees of economic, political and social instability. The Chinese economy is also export-driven and highly reliant on trade. Adverse changes in the economic conditions of its primary trading partners such as the United States, Japan and South Korea would adversely impact the Chinese economy and the relevant Fund investments. The economy of China also differs from the United States economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others. Under China’s political and economic system, the central government may exercise control over the Chinese economy through administrative regulation and/or state ownership. In addition, expropriation, including nationalization, confiscatory taxation, political, economic or social instability or other developments could adversely affect and diminish the values of the Chinese companies in which the Fund invests, however, over the past few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China.
The Fund may invest in shares of Chinese companies traded on stock markets in China or Hong Kong. These stock markets may experience high levels of volatility from time to time. The Hong Kong stock market may behave differently from the China stock markets and there may be little to no correlation between the performance of the Hong Kong stock market and the China stock markets. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Foreign Currency Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Currency Risk – As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case the dollar value of an investment in the Fund would be adversely affected. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Stock Connect Investing Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Stock Connect Investing Risk – Investments in China A shares listed and traded through Stock Connect involve unique risks. Trading through Stock Connect is subject to a number of restrictions that may affect the Fund’s investments and returns. For example, trading through Stock Connect is subject to daily quotas that limit the maximum daily net purchases on any particular day, which may restrict or preclude the Fund’s ability to invest in China A Shares through Stock Connect. In addition, China A Shares purchased through Stock Connect generally may not be sold, purchased or otherwise transferred other than through Stock Connect in accordance with applicable rules. A primary feature of Stock Connect is the application of the home market’s laws and rules applicable to investors in China A Shares. Therefore, the Fund’s investments in China A Shares purchased through Stock Connect are generally subject to Chinese securities regulations and listing rules, among other restrictions. While overseas investors currently are exempt from paying capital gains or value added taxes on income and gains from investments in China A Shares purchased through Stock Connect, these tax rules could be changed, which could result in unexpected tax liabilities for the Fund. Stock Connect will only operate on days when both the China and Hong Kong markets are open for trading and when banks in both markets are open on the corresponding settlement days. There may be occasions when the Fund may be subject to the risk of price fluctuations of China A Shares during the time when Stock Connect is not trading. Moreover, further developments to Stock Connect are likely and there can be no assurance as to the program’s continued existence or whether future developments regarding the program may restrict or adversely affect the Fund’s investments or returns. In addition, the application and interpretation of the laws and regulations of Hong Kong and China, and the rules, policies or guidelines published or applied by relevant regulators and exchanges in respect of Stock Connect are uncertain, and they may have a detrimental effect on the Fund’s investments and returns. |
| Rayliant Wilshire NxtGen Emerging Markets Equity ETF | Participatory Notes Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Participatory Notes Risk – The return on a P-Note is linked to the performance of the issuers of the underlying securities. The performance of P-Notes will not replicate exactly the performance of the issuers that they seek to replicate due to transaction costs and other expenses. P-Notes are subject to counterparty risk since the notes constitute general unsecured contractual obligations of the financial institutions issuing the notes, and the Fund is relying on the creditworthiness of such institutions and has no rights under the notes against the issuers of the underlying securities. In addition, P-Notes are subject to liquidity risk, which is described elsewhere in this section. |

| Rayliant SMDAM Japan Equity ETF | ETF Risks | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks – The Fund is an exchange-traded fund (“ETF”) and, as a result of this structure, it is exposed to the following risks:
Trading Risk – Shares of the Fund may trade on NYSE Arca, Inc. (the “Exchange”) above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Fund’s shares will fluctuate continuously throughout trading hours based on market supply and demand and may deviate significantly from the value of the Fund’s holdings, particularly in times of market stress, with the result that investors may pay more or receive less than the underlying value of the Fund shares bought or sold. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. In stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. These factors, among others, may lead to the Fund’s shares trading at a premium or discount to their NAV and bid-ask spreads may widen. If a shareholder purchases at a time when the market price of the Fund is at a premium to its NAV or sells at time when the market price is at a discount to the NAV, the shareholder may sustain losses.
Cash Transactions Risk – Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to “Authorized Participants.” Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds at least partially in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.
Limited Authorized Participants, Market Makers and Liquidity Providers Risk – Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. |
| Rayliant SMDAM Japan Equity ETF | Large Capitalization Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Risk – The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
| Rayliant SMDAM Japan Equity ETF | Management Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk – The success of the Fund’s strategy is dependent on the Sub-Adviser’s ability and its stock selection process to correctly identify the Fund’s investments. If the Sub-Adviser’s conclusions about growth rates or securities values are incorrect, the Fund may not perform as anticipated. |
| Rayliant SMDAM Japan Equity ETF | Preferred Stock Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk – Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities. |
| Rayliant SMDAM Japan Equity ETF | Foreign Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Company Risk – Investing in foreign companies poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the same level of regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers and foreign markets and securities may be less liquid. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. |
| Rayliant SMDAM Japan Equity ETF | Equity Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Market Risk – The risk that stock prices will fall over short or extended periods of time, sometimes rapidly and unpredictably. The value of equity securities will fluctuate in response to factors affecting a particular company, as well as broader market and economic conditions. Broad movements in financial markets may adversely affect the price of the Fund’s investments, regardless of how well the companies in which the Fund invests perform. A variety of factors can lead to volatility in local, regional, or global markets, including regulatory events, inflation, interest rates, government defaults, government shutdowns, war, regional conflicts, acts of terrorism, social unrest, the imposition of tariffs, trade disputes, and substantial economic downturn or recessions. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Moreover, in the event of a company’s bankruptcy, claims of certain creditors, including bondholders, will have priority over claims of common stock holders such as the Fund. |
| Rayliant SMDAM Japan Equity ETF | Active Management Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk – The Fund is an actively managed portfolio. In managing the Fund’s portfolio securities, the Sub-Adviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results. |
| Rayliant SMDAM Japan Equity ETF | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk – The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to lower the price of the security, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities. |
| Rayliant SMDAM Japan Equity ETF | Derivatives Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk – The Fund’s use of futures contracts is subject to leverage risk, correlation risk, liquidity risk and market risk. Leverage risk and liquidity risk are described below. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Each of the above risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. The other parties to certain derivative contracts present the same types of credit risk as issuers of fixed income securities. The Fund’s use of derivatives may also increase the amount of taxes payable by shareholders. |
| Rayliant SMDAM Japan Equity ETF | Growth Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Growth Style Risk – The Adviser’s or the Sub-Adviser’s growth investment style may increase the risks of investing in the Fund. Because the prices of growth stocks are based largely on the expectation of future earnings, growth stock prices can decline rapidly and significantly when it appears that those expectations will not be met. In addition, a growth investing style may go in and out of favor over time, causing the Fund to sometimes underperform other equity funds that use differing investing styles. |
| Rayliant SMDAM Japan Equity ETF | Portfolio Turnover Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Portfolio Turnover Risk – Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional capital gains tax liabilities, which may affect the Fund’s performance. |
| Rayliant SMDAM Japan Equity ETF | Valuation Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk – The risk that a security may be difficult to value. The Fund may value certain securities at a price higher than the price at which they can be sold, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology (such as during trading halts). Because foreign exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. |
| Rayliant SMDAM Japan Equity ETF | Leverage Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leverage Risk – The Fund’s use of derivatives may result in the Fund’s total investment exposure substantially exceeding the value of its portfolio securities and the Fund’s investment returns depending substantially on the performance of securities that the Fund may not directly own. The use of leverage can amplify the effects of market volatility on the Fund’s share price and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The Fund’s use of leverage may result in a heightened risk of investment loss. |
| Rayliant SMDAM Japan Equity ETF | Large Purchase and Redemption Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Purchase and Redemption Risk – Large purchases or redemptions of the Fund’s shares may force the Fund to purchase or sell securities at times when it would not otherwise do so, and may cause the Fund’s portfolio turnover rate and transaction costs to rise, which may negatively affect the Fund’s performance and have adverse tax consequences for Fund shareholders. |
| Rayliant SMDAM Japan Equity ETF | Small Capitalization Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small Capitalization Companies Risk – The risk that, compared to medium and large capitalization companies, small capitalization companies in which the Fund may invest may be less stable and more susceptible to adverse developments, and their securities may be more volatile and less liquid. |
| Rayliant SMDAM Japan Equity ETF | Geographic Focus Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Focus Risk – To the extent that it focuses its investments in a particular country or geographic region, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within that country or geographic region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments. |
| Rayliant SMDAM Japan Equity ETF | Sector Focus Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Focus Risk – Because the Fund may, from time to time, be more heavily invested in particular sectors, the value of its shares may be especially sensitive to factors and economic risks that specifically affect those sectors. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors. |
| Rayliant SMDAM Japan Equity ETF | Foreign Currency Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Currency Risk – As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case the dollar value of an investment in the Fund would be adversely affected. |
| Rayliant SMDAM Japan Equity ETF | Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Investing in Japan – The growth of Japan’s economy has historically lagged that of its Asian neighbors and other major developed economies. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners. There can be no assurance that overseas demand for the products and services of Japanese companies will not change adversely in the future. China has become an important trading partner with Japan, but the countries’ political relationship has been strained at times. Should political tension increase, it could adversely affect the economy, especially the export sector, and destabilize the region as a whole. Japan also remains heavily dependent on oil imports, and higher commodity prices could therefore have a negative impact on the economy. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the Japanese economy. Japan has, in the past, intervened in the currency markets to attempt to maintain or reduce the value of the yen. Japanese intervention in the currency markets could cause the value of the yen to fluctuate sharply and unpredictably and could cause losses to investors. Japan has an aging workforce and has experienced a significant population decline in recent years. Japan’s labor market appears to be undergoing fundamental structural changes, as a labor market traditionally accustomed to lifetime employment adjusts to meet the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness. Natural disasters, such as earthquakes, volcanoes, typhoons or tsunamis, could occur in Japan or surrounding areas and could negatively affect the Japanese economy and, in turn, the Fund. |
| Rayliant SMDAM Japan Equity ETF | Medium Capitalization Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Medium Capitalization Companies Risk – The risk that medium capitalization companies in which the Fund may invest may have greater price volatility, lower trading volume and be more vulnerable to adverse business or economic events than larger, more established companies. In addition, medium capitalization companies may have narrow product lines, smaller shares of their product or service markets and fewer financial resources than large capitalization companies. |

| Rayliant SMDAM Japan Equity ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk – The Fund is non-diversified, meaning that it may invest a large percentage of its assets in a single issuer or a relatively small number of issuers. Because the Fund is non-diversified, it may be more susceptible to a single adverse economic or political occurrence affecting one or more of the issuers, and may experience increased volatility due to its investments in those securities. However, the Fund intends to satisfy the diversification requirements necessary to qualify as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). |
| Redwheel Global Emerging Equity Fund | Equity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Risk — Since it purchases equity securities, the Fund is subject to the risk that stock prices may fall over short or extended periods of time. Historically, the equity market has moved in cycles, and the value of the Fund’s securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. These factors contribute to price volatility, which is the principal risk of investing in the Fund. |

| Prospectus [Line Items] | |
| Risk [Text Block] | Private Placements Risk — Investment in privately placed securities may be less liquid than investments in publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Further, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that might be applicable if their securities were publicly traded. |
| Redwheel Global Emerging Equity Fund | Foreign Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Company Risk — Investing in foreign companies, including direct investments and investments through depositary receipts, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. While depositary receipts provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in depositary receipts continue to be subject to many of the risks associated with investing directly in foreign securities. |
| Redwheel Global Emerging Equity Fund | Convertible Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities Risk — The value of a convertible security is influenced by changes in interest rates (with investment value declining as interest rates increase and increasing as interest rates decline) and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature. |

| Prospectus [Line Items] | |
| Risk [Text Block] | |
| Redwheel Global Emerging Equity Fund | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk — Certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance. |
| Redwheel Global Emerging Equity Fund | Small- and Mid-Capitalization Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small- and Mid-Capitalization Company Risk — The small- and mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, investments in these small and medium-sized companies may pose additional risks, including liquidity risk, because these companies may have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small- and mid-capitalization stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange. |
| Redwheel Global Emerging Equity Fund | Derivatives Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk — The Fund’s use of equity-linked notes and swaps for all purposes, including speculative purposes, is subject to market risk, correlation risk, credit risk, valuation risk and liquidity risk. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly or at all with the underlying asset, rate or index. Credit risk is the risk that the counterparty to a derivative contract will default or otherwise become unable to honor a financial obligation. Valuation risk is the risk that the derivative may be difficult to value. Liquidity risk is described below. The Fund’s use of swaps is also subject to leverage risk. Leverage risk is the risk that the use of leverage may amplify the effects of market volatility on the Fund’s share price and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. Both U.S. and non-U.S. regulators have adopted and implemented regulations governing derivatives markets, the ultimate impact of which remains unclear. |
| Redwheel Global Emerging Equity Fund | Investment Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Style Risk — The Fund pursues a “growth style” of investing, meaning that the Fund invests in equity securities of companies that RWC US believes will have above-average rates of earnings growth and which, therefore, may experience above-average increases in stock prices. Over time, a growth investing style may go in and out of favor, causing the Fund to sometimes underperform other equity funds that use differing investing styles. |
| Redwheel Global Emerging Equity Fund | Geographic Focus Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Focus Risk — To the extent that it focuses its investments in a particular country or geographic region, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within that country or geographic region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments. |
| Redwheel Global Emerging Equity Fund | Foreign Currency Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Currency Risk — As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedged positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund would be adversely affected. |
| Redwheel Global Emerging Equity Fund | Stock Connect Investing Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Stock Connect Investing Risk — Trading through Stock Connect is subject to a number of restrictions that may affect the Fund’s investments and returns, including a daily quota that limits the maximum net purchases under Stock Connect each day. In addition, investments made through Stock Connect are subject to relatively untested trading, clearance and settlement procedures. Moreover, A-Shares purchased through Stock Connect generally may only be sold or otherwise transferred through Stock Connect. The Fund’s investments in A-Shares purchased through Stock Connect are generally subject to Chinese securities regulations and listing rules. While overseas investors currently are exempt from paying capital gains or value added taxes on income and gains from investments in A-Shares purchased through Stock Connect, these tax rules could be changed, which could result in unexpected tax liabilities for the Fund. Stock Connect operates only on days when both the Chinese and Hong Kong markets are open for trading and when banks in both markets are open on the corresponding settlement days. Therefore, the Fund may be subject to the risk of price fluctuations of A-Shares when Stock Connect is not trading. |
| Redwheel Global Emerging Equity Fund | Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Investing in China — The Chinese economy is generally considered an emerging market and can be significantly affected by economic and political conditions and policy in China and surrounding Asian countries. A relatively small number of Chinese companies represents a large portion of China’s total market and thus may be more sensitive to adverse political or economic circumstances and market movements. The economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others. Under China’s political and economic system, the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership. In addition, expropriation, including nationalization, confiscatory taxation, political, economic or social instability or other developments could adversely affect and significantly diminish the values of the Chinese companies in which the Fund invests. |
| Redwheel Global Emerging Equity Fund | Emerging and Frontier Markets Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging and Frontier Markets Securities Risk — The Fund’s investments in emerging or frontier markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign securities. Unlike more established markets, emerging and frontier markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, the securities markets of emerging and frontier market countries may consist of companies with smaller market capitalizations and may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. |
| Redwheel Global Emerging Equity Fund | Rights and Warrants Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rights and Warrants Risk — Investments in rights or warrants involve the risk of loss of the purchase value of a right or warrant if the right to subscribe to additional shares is not exercised prior to the right’s or warrant’s expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or warrant added to the subscription price of the underlying security may exceed the market price of the underlying security in instances such as those where there is no movement in the price of the underlying security. |
| Redwheel Global Emerging Equity Fund | Risks of Investing in Other Investment Companies | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risks of Investing in Other Investment Companies — To the extent that the Fund invests in other investment companies, such as open-end funds, closed-end funds and ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities held by such other investment companies. As a shareholder of another investment company, the Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of the Fund’s investment could decline, which could adversely affect the Fund’s performance. By investing in another investment company, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses of the other investment company, in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations.
Because ETFs and certain closed-end funds are listed on national stock exchanges and are traded like stocks listed on an exchange, their shares potentially may trade at a discount or premium. Investments in ETFs and certain closed-end funds are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund. In addition, because the value of ETF and certain closed-end fund shares depends on the demand in the market, RWC US may not be able to liquidate the Fund’s holdings at the most optimal time, which could adversely affect Fund performance. |

| Redwheel Next Generation Power Infrastructure Fund | Preferred Stock Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk — Preferred stock is a type of stock that generally pays dividends at a specified rate and that has preference over common stock in the payment of dividends and the liquidation of assets. Preferred stock does not ordinarily carry voting rights. The price of a preferred stock is generally determined by earnings, type of products or services, projected growth rates, experience of management, liquidity, and general market conditions of the markets on which the stock trades. The most significant risks associated with investments in preferred stock include issuer risk, market risk and interest rate risk (i.e., the risk of losses attributable to changes in interest rates). |
| Redwheel Next Generation Power Infrastructure Fund | Convertible Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities Risk — The value of a convertible security is influenced by changes in interest rates (with investment value declining as interest rates increase and increasing as interest rates decline) and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature. |
| Redwheel Next Generation Power Infrastructure Fund | Credit Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Credit Risk - The risk that the issuer of a security or the counterparty to a contract will default or otherwise become unable to honor a financial obligation. A decline in the credit rating of an individual security held by the Fund may have an adverse impact on its price. Rating agencies might not always change their credit rating on an issuer or security in a timely manner to reflect events that could affect the issuer’s ability to make timely payments on its obligations. |
| Redwheel Next Generation Power Infrastructure Fund | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk — Certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance. |
| Redwheel Next Generation Power Infrastructure Fund | Derivatives Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk — The Fund’s use of options, swaps, futures contracts, and hedging is subject to correlation risk, leverage risk, liquidity risk and market risk. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Leverage risk, liquidity risk and market risk are described elsewhere in this section. The Fund’s use of structured notes is also subject to credit risk and valuation risk. Credit risk is described elsewhere in this section. Valuation risk is the risk that the derivative may be difficult to value and/or valued incorrectly. Moreover, certain derivative instruments can magnify the extent of losses incurred due to changes in the market value of the securities to which they relate. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. |
| Redwheel Next Generation Power Infrastructure Fund | Cyber Security Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk — The Fund and its service providers may experience disruptions that arise from breaches in cyber security, human error, processing and communications errors, counterparty or third-party errors, technology or systems failures, any of which may have an adverse impact on the Fund. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, distributor, and other service providers, or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund’s operations, potentially resulting in financial losses to the Fund and its shareholders. |
| Redwheel Next Generation Power Infrastructure Fund | Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk — The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole. |
| Redwheel Next Generation Power Infrastructure Fund | Hedging Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Risk — It is not possible to hedge fully or perfectly against any risk. While hedging can reduce losses, it can also reduce or eliminate gains or cause losses if the market moves in a different manner than anticipated by the Fund or if the cost of the derivative outweighs the benefit of the hedge. Hedging also involves the risk that changes in the value of the derivative will not match those of the holdings being hedged as expected by the Fund, in which case any losses on the holdings being hedged may not be reduced or may be increased. |
| Redwheel Next Generation Power Infrastructure Fund | U.S. Government Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Government Securities Risk — Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency’s own resources. |
| Redwheel Next Generation Power Infrastructure Fund | Emerging and Frontier Markets Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging and Frontier Markets Securities Risk — The Fund’s investments in emerging or frontier markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign securities. Unlike more established markets, emerging and frontier markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, the securities markets of emerging and frontier market countries may consist of companies with smaller market capitalizations and may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. |
| Redwheel Next Generation Power Infrastructure Fund | Rights and Warrants Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rights and Warrants Risk — Investments in rights or warrants involve the risk of loss of the purchase value of a right or warrant if the right to subscribe to additional shares is not exercised prior to the right’s or warrant’s expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or warrant added to the subscription price of the underlying security may exceed the market price of the underlying security in instances such as those where there is no movement in the price of the underlying security. |
| Redwheel Next Generation Power Infrastructure Fund | Equity Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk — Since it purchases equity securities, the Fund is subject to the risk that stock prices may fall over short or extended periods of time. Historically, the equity market has moved in cycles, and the value of the Fund’s securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. These factors contribute to price volatility, which is the principal risk of investing in the Fund. |
| Redwheel Next Generation Power Infrastructure Fund | Renewable Energy Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Renewable Energy Company Risk — Because the Fund invests in renewable energy companies, the value of Fund shares may be affected by events that adversely affect that industry, such as technology shifts, short product lifecycles, falling prices and profits, competition and general economic conditions, and may fluctuate more than that of a fund that does not concentrate in sustainable energy solutions companies. |
| Redwheel Next Generation Power Infrastructure Fund | Adviser Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Adviser Risk — The Fund may not meet its investment objective or may underperform the market or other mutual funds with similar strategies if RWC UK cannot successfully implement the Fund’s investment strategies. |
| Redwheel Next Generation Power Infrastructure Fund | Concentration Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Concentration Risk — The Fund’s strategy of focusing its investments in Renewable Infrastructure companies means that the performance of the Fund will be closely tied to the performance of the renewable electricity and utility infrastructure industry. The Fund’s focus in this industry presents more risk than if it were broadly diversified over numerous industries and sectors of the economy. An inherent risk associated with any investment focus is that the Fund may be adversely affected if one or two of its investments perform poorly. |
| Redwheel Next Generation Power Infrastructure Fund | Energy Infrastructure Industry Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Energy Infrastructure Industry Risk — Companies in the energy infrastructure industry are subject to many risks that can negatively impact the revenues and viability of companies in this industry, including, but not limited to risks associated with companies owning power infrastructure, propane assets, as well as capital markets, terrorism, natural disasters, climate change, operating, regulatory, environmental, supply and demand, and price volatility risks. |
| Redwheel Next Generation Power Infrastructure Fund | Renewable Energy Infrastructure Industry Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Renewable Energy Infrastructure Industry Risk — Companies in the renewable energy infrastructure industry are subject to many business, economic, environmental, and regulatory risks that can adversely affect the costs, revenues, profits, and viability of companies in the industry. These risks include, but are not limited to, the following: volatility in competing commodity prices and changes in supply and demand, which may affect the volume of energy commodities transported, processed, stored and or distributed; specific risks associated with companies owning and/or operating renewable energy or utility transmission systems; operating risks including outages, structural and maintenance, impairment and safety problems; changes in the regulatory environment at federal, state and local levels, and in foreign markets; environmental regulation and liability risk; terrorism risk; extreme weather and other natural disasters; and capital markets risk, resulting in a higher capital costs or impacting growth and access to capital. |
| Redwheel Next Generation Power Infrastructure Fund | New Technology Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Technology Risk — New technologies used in renewable energy have a shorter commercial experience vs traditional energy production technologies. Also, advancements in renewable energy may create disruptive competitive threats to both incumbent technologies, such as centralized electric transmission and distribution networks; in progressively more efficient or lower cost versions of existing renewable technology, or possibly advancements or innovations in competing renewable technology. |
| Redwheel Next Generation Power Infrastructure Fund | ESG Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ESG Risk — A company’s ESG score is one factor considered by RWC UK when determining whether to buy or sell a security. The Fund may purchase and hold securities that present ESG risks. The evaluation of ESG factors is often subjective and RWC UK may not identify or evaluate every relevant ESG factor with respect to every investment. As a result, the ESG evaluation performed by RWC UK may differ from the evaluations made by other investment advisers and may not reflect the beliefs or values of any particular investor. In addition, the evaluation of ESG factors and implementation of ESG-related investment restrictions (i.e., screens) rely on the availability of timely, complete and accurate ESG data being reported by issuers and/or third-party research providers, and ESG-related data is often based on estimates or assumptions. RWC UK’s ability to evaluate and assess ESG factors and the successful implementation of ESG-related investment restrictions may be limited or compromised to the extent relevant data is unavailable or inaccurate. The integration of ESG considerations may also cause the Fund to perform differently compared to accounts that do not integrate ESG considerations. For example, ESG considerations may result in the Fund foregoing opportunities to buy certain securities when it might otherwise be advantageous to do so. Further, an increased focus on ESG or sustainability investing in recent years may have led to increased valuations of certain issuers with higher ESG profiles. A reversal of that trend could result in losses with respect to investments in such issuers. |
| Redwheel Next Generation Power Infrastructure Fund | Foreign Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk — Investing in foreign companies, including direct investments and investments through depositary receipts, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. While depositary receipts provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in depositary receipts continue to be subject to many of the risks associated with investing directly in foreign securities. |
| Redwheel Next Generation Power Infrastructure Fund | ADR Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ADR Risk — Investments in ADRs may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. |
| Redwheel Next Generation Power Infrastructure Fund | Large Cap Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Cap Company Risk — If valuations of large capitalization companies appear to be greatly out of proportion to the valuations of small or medium capitalization companies, investors may migrate to the stocks of small and medium-sized companies. The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
| Redwheel Next Generation Power Infrastructure Fund | Small and Mid-Cap Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small and Mid-Cap Companies Risk — The small- and mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, investments in these small and medium-sized companies may pose additional risks, including liquidity risk, because these companies may have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small- and mid-capitalization stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange. |
| Redwheel Next Generation Power Infrastructure Fund | Debt Securities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Debt Securities Risk — The prices of the Fund’s fixed-income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. Generally, the Fund’s fixed-income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed-income markets. |
| Redwheel Next Generation Power Infrastructure Fund | Government-Sponsored Entities Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Government-Sponsored Entities Risk — The Fund may invest in securities issued or guaranteed by government-sponsored entities. However, these securities may not be guaranteed or insured by the U.S. government and may only be supported by the credit of the issuing agency. |
| Redwheel Next Generation Power Infrastructure Fund | REIT Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REIT Risk — REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. REITs are susceptible to the risks associated with direct ownership of real estate, such as the following: declines in property values; increases in property taxes, operating expenses, interest rates or competition; overbuilding; zoning changes; and losses from casualty or condemnation. REITs typically incur fees that are separate from those of the Fund. Accordingly, the Fund’s investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses. REIT operating expenses are not reflected in the fee table and example in this prospectus. |
| Redwheel Next Generation Power Infrastructure Fund | Investment Company and RIC Compliance Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Company and RIC Compliance Risk — To the extent that the Fund invests in other investment companies, such as open-end funds, closed-end funds and ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities held by such other investment companies. As a shareholder of another investment company, the Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of the Fund’s investment could decline, which could adversely affect the Fund’s performance. By investing in another investment company, Fund shareholders indirectly bear the Fund’s proportionate share of the fees and expenses of the other investment company, in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations.
Because ETFs and certain closed-end funds are listed on national stock exchanges and are traded like stocks listed on an exchange, their shares potentially may trade at a discount or premium. Investments in ETFs and certain closed-end funds are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund. In addition, because the value of ETF and certain closed-end fund shares depends on the demand in the market, RWC UK may not be able to liquidate the Fund’s holdings at the most optimal time, which could adversely affect Fund performance.
For any taxable year the Fund fails to qualify as a RIC, the Fund’s taxable income will be subject to federal income tax at regular corporate rates. The resulting increase to the Fund’s expenses will reduce its performance and its income available for distribution to shareholders. |
| Redwheel Next Generation Power Infrastructure Fund | Initial Public Offering IPO Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Initial Public Offering (“IPO”) Risk — The market value of shares issued in an IPO may fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about a company’s business model, quality of management, earnings growth potential, and other criteria used to evaluate its investment prospects. Accordingly, investments in IPO shares involve greater risks than investments in shares of companies that have traded publicly on an exchange for extended periods of time. Investments in IPO shares may also involve high transaction costs, and are subject to market risk and liquidity risk, which are described elsewhere in this section. |
| Redwheel Next Generation Power Infrastructure Fund | Tax Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tax Risk — Income from certain exchange traded products that invest in commodities and other non-security based asset classes, as well as direct investments in such alternative asset classes such as gold, may not be qualifying income for purposes of the qualifying income test that must be met by the Fund in order to qualify as a RIC under Subchapter M of the Code. The Fund will seek to restrict its income from direct investments in such alternative investments that do not generate qualifying income to a maximum of 10% of its gross income (when combined with its other investments that produce non-qualifying income) to comply with certain qualifying income tests necessary for the Fund to qualify as a RIC under the Code. However, there is no guarantee that the Fund will be successful in this regard. If the Fund fails to qualify as a RIC and to avail itself of certain relief provisions, it would be subject to tax at the regular corporate rate without any deduction for distributions to shareholders, and its distributions would generally be taxable as dividends. Please see the Fund’s Statement of Additional Information (the “SAI”) for a more detailed discussion, including the availability of certain relief provisions for certain failures by the Fund to qualify as a RIC. The tax treatment of certain commodity investments and other non-security based instruments may be affected by future regulatory or legislative changes that could affect the character, timing and/or amount of the Fund’s taxable income or gains and distributions. The Fund’s pursuit of its investment objective will potentially be limited by the Fund’s intention to qualify for treatment as a RIC. The Fund can make certain investments, the treatment of which is unclear under the Code and could adversely affect the Fund’s ability to qualify as a RIC. |
| Redwheel Next Generation Power Infrastructure Fund | Futures Contracts Risk | |

| Risk [Text Block] | Futures Contracts Risk — The price of a futures contract may change rapidly in response to changes in the markets and the general economic environment. Futures investments may result in investment exposures that are greater than their cost would suggest, meaning that a small investment in futures could have a large potential effect on the performance of the Fund. Generally, the purchase of a futures contract will increase the Fund’s exposure to the volatility of the underlying asset while the value of a futures contract that is sold will perform inversely to the underlying asset. The successful use of futures by the Fund will be subject to RWC UK’s ability to predict correctly movements in the direction of relevant markets, as well as interest rates, currency exchange rates and other economic factors. |
| Redwheel Next Generation Power Infrastructure Fund | Options Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Options Risk — Purchasing and writing put and call options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. |
| Redwheel Next Generation Power Infrastructure Fund | Swap Agreements Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Swap Agreements Risk — A swap is a derivative that provides leverage, allowing the Fund to obtain exposure to an underlying asset, reference rate or index in an amount that is greater than the amount the Fund has invested. By using swap agreements, the Fund is exposed to counterparty credit risk. The use of swap agreements could cause the Fund to be more volatile, resulting in larger gains or losses in response to changes in the values of the assets, reference rates or indices underlying the swap agreements than if the Fund had made direct investments in such assets, reference rates or indices. |

| Redwheel Next Generation Power Infrastructure Fund | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversified Fund Risk — The Fund is classified as “non-diversified,” which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent that the Fund invests its assets in a smaller number of issuers, the Fund will be more susceptible to negative events affecting those issuers than a diversified fund. Accordingly, the limited number of issuers in which the Fund invests means that each issuer has a proportionately greater impact on the Fund’s returns. However, the Fund intends to satisfy the asset diversification requirements for qualifying as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). |
| SouthernSun Small Cap Fund | Value Style Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value Style Risk — Value investing focuses on companies with stocks that appear undervalued in light of factors such as the company’s earnings, book value, revenues or cash flow. If the Adviser’s assessment of market conditions, or a company’s value or prospects for exceeding earnings expectations is wrong, the Fund could suffer losses or produce poor performance relative to other funds. In addition, “value stocks” can continue to be undervalued by the market for long periods of time. |
| SouthernSun Small Cap Fund | Management Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk — The value of the Fund may decline if the Adviser’s judgments about the attractiveness, relative value or potential appreciation of a particular security or strategy prove to be incorrect. |
| SouthernSun Small Cap Fund | Foreign Company Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Company Risk — The Fund may invest in foreign companies traded on U.S. exchanges. Accordingly, changes in foreign economies and political climates are more likely to affect the Fund than a fund that invests exclusively in U.S. companies. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. The value of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. |
| SouthernSun Small Cap Fund | Liquidity Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk — The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance. |
| SouthernSun Small Cap Fund | Market Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk — The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. A variety of factors can lead to volatility in local, regional, or global markets, including regulatory events, inflation, interest rates, governmental defaults, government shutdowns, war, regional conflicts, acts of terrorism, social unrest, the imposition of tariffs, trade disputes, and substantial economic downturn or recessions. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole. |
| SouthernSun Small Cap Fund | Sector Emphasis Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Emphasis Risk — The securities of companies in the same business sector, if comprising a significant portion of the Fund’s portfolio, may in some circumstances react negatively to market conditions, interest rates and economic, regulatory or financial developments and adversely affect the value of the portfolio to a greater extent than if such securities comprised a lesser portion of the Fund’s portfolio or the Fund’s portfolio was diversified across a greater number of industry sectors. |
| SouthernSun Small Cap Fund | Small Capitalization Companies Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small-Capitalization Companies Risk — Small capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization stocks may be more volatile than those of larger companies. Small capitalization stocks may be traded over-the-counter or listed on an exchange. |
| SouthernSun Small Cap Fund | Industrials Sector Risk | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Industrials Sector Risk — A fund with substantial holdings in the industrials sector may be subject to greater risks than a portfolio without such a focus. The Fund is subject to the risk that the securities of issuers in the industrials sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the industrials sector. The prices of the securities of companies operating in the industrials sector may fluctuate due to the level and volatility of commodity prices, the exchange value of the dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices. |

| Risk [Text Block] | Small- and Mid-Capitalization Companies Risk — The small- and mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, investments in these small- and mid-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small- and mid-cap stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange. |
