The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Portfolio. Portfolio shares may be purchased only by or on behalf of separately managed account clients where Nuveen Asset Management, LLC has an agreement to serve as investment adviser or sub-adviser to the account with the separately managed account program sponsor or directly with the client. The fees and expenses in the following tables do not reflect any charges that are imposed by the separately managed accounts. If such charges were reflected, the fees and expenses would be higher than what is shown below.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in annual portfolio operating expenses or in the example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 38% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock
The following example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year, that the Portfolio’s operating expenses remain the same and that the expense reimbursements continue to remain in place. The example does not reflect any charges that are imposed by the separately managed accounts. If such charges were reflected, the costs would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Portfolio invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in preferred securities or other income producing securities. The Portfolio may invest in all types of preferred securities, including both perpetual preferred securities and hybrid securities. Perpetual preferred securities are generally equity securities of the issuer that have priority over the issuer’s common shares as to the payment of dividends (i.e., the issuer cannot pay dividends on its common shares until the dividends on the preferred shares are current) and as to the payout of proceeds of a bankruptcy or other liquidation, but are subordinate to an issuer’s senior debt and junior debt as to both types of payments. Additionally, in a bankruptcy or other liquidation, perpetual preferred securities are generally subordinate to an issuer’s trade creditors and other general obligations. Perpetual preferred securities typically have a fixed liquidation (or “par”) value.
The term “preferred securities” also includes hybrid securities and other types of preferred securities that do not have the features described above. Preferred securities that are hybrid securities often behave similarly to investments in perpetual preferred securities and are regarded by market investors as being part of the preferred securities market. Such hybrid securities possess varying combinations of features of both debt and perpetual preferred securities and as such they may constitute senior debt, junior debt or preferred shares in an issuer’s capital structure.
The term “preferred securities” also includes certain forms of debt that are regarded by the investment marketplace to be part of the broader preferred securities market. Among these preferred securities are certain exchange-listed debt issues that historically have several attributes, including trading and investment performance characteristics, in common with exchange-listed perpetual preferred securities and hybrid securities. Generally, these types of preferred securities are senior debt in the capital structure of an issuer.
The Portfolio may also invest in income producing securities that are not preferred securities. These include contingent capital securities (sometimes referred to as “CoCos”), which are hybrid securities, issued primarily by non-U.S. financial institutions, that have loss absorption mechanisms benefitting the issuer built into their terms. These loss absorption mechanisms may include automatic conversion into the issuer’s common stock or an automatic write down of the security’s principal amount upon the occurrence of a specified trigger or event. In addition, although the Portfolio will invest primarily in preferred securities and CoCos, it may invest up to 20% of its assets, in the aggregate, in corporate debt securities, U.S. government securities (including securities issued or guaranteed by U.S. government agencies and instrumentalities) and taxable municipal securities.
The Portfolio may also invest in preferred securities or CoCos that are convertible into common stock.
The Portfolio may invest up to 50% of its assets in securities rated lower than investment grade or unrated securities of comparable quality as determined by the Portfolio’s sub-adviser (securities commonly referred to as “high-yield” securities or “junk” bonds). The Portfolio may also invest in U.S. dollar-denominated securities issued by non-U.S. companies.
The Portfolio may invest in securities that have not been registered under the Securities Act of 1933, but that may be resold to qualified institutional buyers in accordance with the provisions of Rule 144A under the Securities Act of 1933 (“Rule 144A securities”).
The Portfolio intends to invest at least 25% of its assets in the securities of companies principally engaged in financial services.
Developed exclusively for use within separately managed accounts advised or sub-advised by Nuveen Asset Management, LLC, the Portfolio is a specialized fixed-income portfolio to be used in combination with selected individual securities to effectively model institutional-level investment strategies. The Portfolio enables certain Nuveen separately managed account investors to achieve greater diversification and return potential than might otherwise be achieved by investing in additional fixed-income classes, including those that have a lower credit quality and potentially higher yielding securities.

The table below shows the variability of the Portfolio’s average annual returns and how they compare over the time periods indicated with those of broad measures of market performance. In accordance with new regulatory requirements, the Portfolio has selected the Bloomberg U.S. Aggregate Bond Index, which represents a broad measure of market performance, and is generally representative of the market sectors or types of investments in which the Portfolio invests. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here.
Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers had not been in place, returns would have been reduced.

Nuveen Preferred Securities and Income Managed Accounts Portfolio | Active Management Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Active Management Risk—The Portfolio’s sub-adviser actively manages the Portfolio’s investments. Consequently, the Portfolio is subject to the risk that the investment techniques and risk analyses employed by the Portfolio’s sub-adviser
may not produce the desired results. This could cause the Portfolio to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Call Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Call Risk—If, during periods of falling interest rates, an issuer exercises its right to prepay principal on its higher-yielding debt securities held by the Portfolio, the Portfolio may have to reinvest in securities with lower yields or higher risk of default, which may adversely impact the Portfolio’s performance.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Contingent Capital Security Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Contingent Capital Security Risk—CoCos have loss absorption mechanisms benefitting the issuer built into their terms. Upon the occurrence of a specified trigger or event, CoCos may be subject to automatic conversion into the issuer’s common stock, which likely will have declined in value and which will be subordinate to the issuer’s other classes of securities, or to an automatic write-down of the principal amount of the securities, potentially to zero, which could result in the Portfolio losing a portion or all of its investment in such securities. CoCos are often rated below investment grade and are subject to the risks of high yield securities.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Convertible Security Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Convertible Security Risk—Convertible securities are subject to certain risks of both equity and debt securities. The value of convertible securities may decline in response to such factors as rising interest rates and fluctuations in the market price of the common stock underlying the convertible securities.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Credit Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Credit Risk—Credit risk is the risk that an issuer or other obligated party of a security may be, or perceived (whether by market participants, rating agencies, pricing services or otherwise) to be, unable or unwilling to make dividend, interest and principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability or willingness to make such payments.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Credit Spread Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Credit Spread Risk—Credit spread risk is the risk that credit spreads (i.e., the difference in yield between securities that is due to differences in their credit quality) may increase when the market believes that bonds generally have a greater risk of default. Increasing credit spreads may reduce the market values of the Portfolio’s debt securities. Credit spreads often increase more for lower rated and unrated securities than for investment grade securities. In addition, when credit spreads increase, reductions in market value will generally be greater for longer-maturity securities.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Currency Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Currency Risk—Even though the non-U.S. securities held by the Portfolio are traded in U.S. dollars, their prices are typically indirectly influenced by currency fluctuations. Changes in currency exchange rates may affect the Portfolio’s net asset value, the value of dividends and interest earned, and gains or losses realized on the sale of securities.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Cybersecurity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Cybersecurity Risk—Cybersecurity risk is the risk of an unauthorized breach and access to Portfolio assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Portfolio, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider, a financial intermediary or the issuers of securities held by the Portfolio to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Portfolio, its service providers or the issuers of securities held by the Portfolio may adversely impact the Portfolio or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Portfolio invests, which may cause the Portfolio’s investments to lose value.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Financial Services Sector Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Financial Services Sector Risk—The Portfolio's policy to concentrate in financial services companies makes the Portfolio more susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are particularly sensitive to the adverse effects of economic recession; changes in government regulation; the availability of capital; volatile interest rates; and the health of the commercial and residential real estate markets.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Foreign Investment Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Foreign Investment Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad, as well as armed conflicts and different legal, regulatory and tax environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Portfolio invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | High Yield Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, and unrated securities of comparable quality are high risk investments that may cause income and principal losses for the Portfolio. They generally are considered to be speculative with respect to the ability to pay interest and
repay principal, have greater credit risk, are less liquid, are more likely to experience a default and have more volatile prices than investment grade securities.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Income Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Income Risk—The Portfolio's income could decline during periods of falling interest rates or when the Portfolio experiences defaults on debt securities or defaults or deferrals on preferred securities it holds.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Interest Rate Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Interest Rate Risk—Interest rate risk is the risk that the value of the Portfolio’s fixed-rate securities will decline because of rising interest rates. Changing interest rates may have unpredictable effects on markets, result in heightened market volatility and detract from the Portfolio’s performance to the extent that it is exposed to such interest rates. Fixed-rate securities may be subject to a greater risk of rising interest rates than would normally be the case due to the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Higher periods of inflation could lead to government fiscal policies which raise interest rates. When interest rates change, the values of longer-duration fixed-rate securities usually change more than the values of shorter-duration fixed-rate securities. Conversely, fixed-rate securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-rate securities with longer durations or maturities. Rising interest rates also may lengthen the duration of securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. The Portfolio is also subject to the risk that the income generated by its investments may not keep pace with inflation. There is a risk that interest rates across the financial system may change, possibly significantly and/or rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market participants may lead to decreased liquidity and increased volatility in the fixed-rate or debt markets, making it more difficult for the Portfolio to sell fixed-rate investments. Changes in interest rates may also lead to an increase in Portfolio redemptions, which may result in higher portfolio turnover costs, thereby adversely affecting the Portfolio’s performance.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Market Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Market Risk—The market value of the Portfolio’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Portfolio’s investments whether or not the Portfolio invests in such country or region. Events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Portfolio’s assets can decline.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Market Liquidity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Market Liquidity Risk—Reductions in trading activity or dealer inventories of securities such as bonds and preferred securities, which provide an indication of the ability of financial intermediaries to “make markets” in those securities, have the potential to decrease liquidity and increase price volatility in the markets in which the Portfolio invests, particularly during periods of economic or market stress. In addition, federal banking regulations may cause certain dealers to reduce their inventories of securities, which may further decrease the Portfolio’s ability to buy or sell securities. As a result of this decreased liquidity, the Portfolio 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 performance. If the Portfolio needed to sell large blocks of securities to meet shareholder redemption requests or to raise cash, those sales could further reduce the securities’ prices and hurt performance.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Municipal Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Municipal Securities Risk—The values of municipal securities held by the Portfolio may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. The amount of public information available about municipal bonds is generally less than for certain corporate equities or bonds, meaning that the investment performance of the Portfolio may be more dependent on the analytical abilities of the Portfolio’s sub-adviser than funds that invest in stock or other corporate investments.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Preferred Security Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Preferred Security Risk—Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having fixed interest rates or dividends, which may result in a decline in value in a rising interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Restricted Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Restricted Securities Risk—The market for restricted securities, including Rule 144A securities, typically is less active than the market for publicly traded securities. Rule 144A securities and other securities exempt from registration under the Securities Act carry the risk that their liquidity may become impaired and the Portfolio may be unable to dispose of the securities promptly or at current market value.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Unrated Security Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Unrated Security Risk—Unrated securities determined by the Portfolio’s sub-adviser to be of comparable quality to rated securities which the Portfolio may purchase may pay a higher interest rate than such rated securities and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated securities or issuers than rated securities or issuers.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | U S Government Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
U.S. Government Securities Risk—U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Securities issued or guaranteed by U.S. government agencies and instrumentalities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. government or may be subject to certain limitations. No assurance can be given that the U.S. government will provide financial support to its agencies and instrumentalities if it is not obligated by law to do so, which may increase the risk of loss to the Portfolio.
Nuveen Preferred Securities and Income Managed Accounts Portfolio | Valuation Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Valuation Risk—The sales price the Portfolio could receive for any particular debt security may differ from the Portfolio’s valuation of the investment, particularly for debt securities that trade in thin or volatile markets or that are valued using a fair value methodology. The debt securities in which the Portfolio invests typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including price quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Portfolio will be able to buy or sell a portfolio security at the price established by the pricing service, which could result in a gain or loss to the Portfolio. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Over certain time periods, such differences could materially impact the performance of the Portfolio, which may not be sustainable. Alternative pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Portfolio were to change pricing services, or if the Portfolio’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Portfolio’s net asset value.
