| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is a newly-organized, actively managed exchange-traded fund (“ETF”) that does not seek to replicate the performance of a specified index. The Fund invests, under normal circumstances, at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in private credit collateralized loan obligations (“CLOs”). A CLO is a type of asset backed security supported by interest and principal payments generated from a pool of loans, which may include, among others, U.S. and non-U.S. senior secured loans and subordinated corporate loans and privately placed loans. The term “private credit” refers to lending activity that occurs outside of the broadly-syndicated markets where banks and other traditional lenders place an issuer’s debt obligations across a wide range of investors. For purposes of the Fund’s 80% policy, the Fund expects private credit CLOs to be CLOs in which at least 80% of each such CLO consists of a pool of loans to companies that are privately-owned and do not issue equity securities in the public markets (“private credit CLOs,” also commonly known as “middle market CLOs”). The companies underlying these private credit CLOs can be companies of any size, although middle market CLOs are typically backed by pools of loans to small or medium-sized private companies with EBITDA values of $100 million or less. The Fund expects that each private credit CLO will consist of loans where at least 80% of the total companies within the CLO are private or where at least 80% of total loan amounts within the CLO are issued to private companies. The Fund may temporarily deviate from its 80% policy while deploying new capital as the result of the initial seeding of the Fund, as a result of cash creation or redemption activity, or during unusual market conditions such as a downgrade in the rating of one or more private credit CLOs.
The Fund may invest up to 20% of its net assets (plus the amount of any borrowings for investment purposes) in broadly syndicated bank loans, broadly syndicated bank loans CLOs, high yield bonds, investment grade bonds and cash. The Fund will not invest more than 10% of its net assets (plus the amount of any borrowings for investment purposes) in any single CLO. The Fund may invest in floating- and fixed-rate CLOs, but will not invest more than 20% of its net assets (plus the amount of any borrowings for investment purposes) in fixed-rate CLOs. The Fund may purchase CLOs both in the primary and secondary markets. Additionally, the credit obligations in which the Fund invests through its CLO investments may include newly-issued securities, or “new issues,” such as initial debt offerings or newly-issued loans.
The Fund primarily invests in securities rated investment grade at the time of purchase. Investment grade securities are considered to be those instruments that are rated BBB- or higher by S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”), or Baa3 or higher by Moody’s Investors Service, Inc. (“Moody’s”), or the equivalent by another nationally recognized statistical rating organization (“NRSRO”), or if unrated, are determined by the Sub-Adviser (as defined below) to be of comparable quality. The Fund may also invest up to 25% of its net assets (plus the amount of any borrowings for investment purposes) in securities rated below investment grade by an NRSRO (inclusive of private credit CLOs and broadly syndicated loan CLOs), or, if unrated, determined by the Sub-Adviser to be of comparable quality including securities in the lowest rating categories and comparable unrated securities (commonly referred to as “high yield” or “junk bonds”). In the event that a security receives different ratings from different NRSROs, the Fund will treat the security as being rated in the highest rating category received from an NRSRO. The Fund may invest in the aggregate up to 25% of its net assets (plus the amount of any borrowings for investment purposes) in non-U.S. dollar denominated instruments. The Fund may seek to limit its risk or enhance returns through derivatives designed to adjust the Fund’s exposure to interest rates, foreign currency, portfolio duration and specific securities or baskets of securities. In selecting investments for the Fund, the Sub-Adviser will evaluate overall investment opportunities and risks among the types of investments the Fund may hold.
The Fund engages in active trading—that is, frequent trading of its securities—in order to take advantage of new investment opportunities. The Fund expects to be more heavily involved in active trading during periods of market volatility seeking to preserve gains or limit losses.
The Fund is “non-diversified” for purposes of the Investment Company Act of 1940, as amended (the “1940 Act”), which means that it may invest a greater percentage of its assets in a particular issuer and may invest in fewer issuers than a diversified fund.
The Fund may invest up to 20% of its net assets in certain futures, options and swap contracts, U.S. Treasury obligations, U.S. Government obligations, U.S. agency securities, securities of other registered investment companies, cash and cash equivalents. Instead of, or in addition to, investing directly in particular securities, the Fund may invest in derivative instruments, including futures, forwards, options, swaps, and options on swaps, to try to enhance return or to try to reduce (“hedge”) investment risks.
The Adviser has retained Delaware Investments Fund Advisers, a series of Macquarie Investment Management Business Trust, a Delaware statutory trust, to serve as the Fund’s investment sub-adviser (the “Sub-Adviser”). In managing the Fund’s assets, the Sub-Adviser uses a combination of top-down economic analysis and bottom-up research in conjunction with proprietary quantitative models, and risk management systems. In the top-down economic analysis, the Sub-Adviser develops views on economic, policy and market trends by continually evaluating economic data that affect the movement of markets and securities prices. This top-down macroeconomic analysis is integrated into the Sub-Adviser’s bottom-up research which informs security selection. In its bottom-up research, the Sub-Adviser develops an internal rating and outlook on issuers. The rating and outlook are determined based on a thorough review of the financial health and trends of the issuer. The Sub-Adviser may also consider investment factors such as expected total return, yield, spread and potential for price appreciation as well as credit quality, maturity and risk. The Fund may invest in a security based upon the expected total return rather than the yield of such security.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk Caption | rr_RiskCaption | The Fund is classified as a “non-diversified” fund under the 1940 Act. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely. | |||||||||||||||||||||||||||||||

| Risk [Text Block] | rr_RiskTextBlock | As with any investment, you could lose all or a substantial part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below. Any such risk may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.
|
|||||||||||||||||||||||||||||||
| BondBloxx Private Credit CLO ETF | C L O Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | CLO Risk. The risks of investing in CLOs include both the economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments. The degree of such risk will generally correspond to the specific tranche in which the Fund is invested. The Fund intends to invest primarily in investment grade-rated private credit CLOs; however, any such ratings do not constitute a guarantee, may be downgraded, and in stressed market environments it is possible that even investment grade rated CLO tranches could experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and the disappearance of the subordinated/equity tranches, market anticipation of defaults, as well as negative market sentiment with respect to CLO securities as an asset class. The Sub-Adviser may not be able to accurately predict how specific CLOs or the portfolio of underlying loans for such CLOs will react to changes or stresses in the market, including changes in interest rates. The most common risks associated with investing in CLOs are liquidity risk, interest rate risk, credit risk, prepayment risk, and the risk of default of the underlying asset, among others. These risks may be heightened for private credit CLOs, as the portfolios of underlying loans for such CLOs are typically smaller than those of broadly syndicated loan CLOs, and as such, private credit CLOs may not have the same access to the capital markets to potentially mitigate and/or diversify such risks.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Debt Securities Risk. Variable-and floating-rate debt obligations (including CLOs and the portfolio of loans underlying the CLOs), as well as fixed-income debt instruments are subject to the following risks.
|

| BondBloxx Private Credit CLO ETF | Collateralized Loan Obligations Leveraging Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Collateralized Loan Obligations Leveraging Risk. CLOs are typically leveraged, and such leverage will magnify the loss on CLO investments, which may in turn magnify the loss experienced by the Fund. The cumulative effect of the use of leverage with respect to any investments in a market that moves adversely to such investments could result in a substantial loss that would be greater than if the Fund’s investments were not leveraged. The Fund will invest primarily in investment grade rated tranches of CLOs, which generally are less affected by the effects of leverage than more junior tranches.
|
|||||||||||||||||||||||||||||||
| BondBloxx Private Credit CLO ETF | Below Investment Grade C L O Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Below Investment Grade CLO Risk. Debt securities rated below investment grade (including CLOs) are also referred to as high yield securities or “junk securities.” Such securities may be more sensitive than investment grade CLO securities to economic changes, political changes, industry or sector-specific changes, or adverse developments specific to the underlying loans of a CLO, which may adversely affect the value of the below investment grade CLO security. Below investment grade CLO securities are those rated below investment grade by the primary rating agencies such as S&P, Fitch, and Moody’s or are unrated CLOs of similar quality. The value of lower quality CLO securities is generally more dependent on credit risk than investment grade CLO securities. Issuers of the below investment grade loans that underlie a CLO may not be as strong financially as those issuers with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the below investment grade CLO market is considered to be speculative in nature and can experience sudden and sharp price swings.

| BondBloxx Private Credit CLO ETF | C L O Manager Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | CLO Manager Risk. CLOs are managed by investment advisers independent of the Adviser and the Sub-Adviser. CLO managers are responsible for selecting, managing and replacing the underlying loans within a CLO. CLO managers may have limited operating histories, may be subject to conflicts of interests, including managing the assets of other clients or other investment vehicles, or receiving fees that incentivize maximizing the yield, and indirectly the risk, of a CLO. Adverse developments with respect to a CLO manager, such as personnel and resource constraints, regulatory issues or other developments that may impact the ability and/or performance of the CLO manager, may adversely impact the performance of the CLO securities in which the Fund invests. This risk may be more pronounced given the Fund’s investments in private credit CLOs.

| BondBloxx Private Credit CLO ETF | Middle Market Loan Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Middle Market Loan Risk. Investment in middle market companies involves a number of significant risks. Generally, little public information exists about these companies, and the Fund is required to rely on the ability of the Sub-Adviser’s investment professionals to obtain adequate information to evaluate the potential returns from investing in these companies. If the Sub-Adviser is unable to uncover all material information about these companies, it may not be able to make a fully informed investment decision, and the Fund may lose money on is investments.
|
|||||||||||||||||||||||||||||||
| BondBloxx Private Credit CLO ETF | Broadly Syndicated Bank Loans Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Broadly Syndicated Bank Loans Risk. The Fund may invest directly or indirectly in broadly syndicated bank loans. Broadly syndicated bank loans (“BSLs”) are typically originated and structured by banks on behalf of large corporate borrowers. The proceeds of BSLs are often used for leveraged buyout transactions, mergers and acquisitions, recapitalizations, refinancings, and financing capital expenditures. BSLs are typically distributed by the arranging bank to a diverse group of investors primarily consisting of: CLOs; senior secured loan and high yield bond mutual funds; closed-end funds, hedge funds, banks, and insurance companies; and finance companies. A borrower must comply with various covenants contained in a loan agreement or note purchase agreement between the borrower and the holders of the broadly syndicated loan. Investments in BSLs may expose the Fund to different risks, including with respect to liquidity, price volatility, ability to restructure loans, credit risks and less protective loan documentation. Fluctuations in the market price of securities may affect the value of the BSL’s investments and may increase the risks inherent in such investments. The ability to sell the investments in the market may depend on demand, which may be impracticable or impossible in certain market environments. Despite diversification, high concentration may arise in certain markets. Problems may be encountered in the valuation or sale of certain investments, and in some cases, investments may have to be sold below their value. Some investments may involve assets which are exposed to high market, credit and liquidity risks (including the risk of insolvency or bankruptcy of the borrower). Investments may be leveraged at the level of the investment (e.g., by margin borrowing or otherwise). If the capital gains on the investments acquired with leverage are greater than the interest on the loans, the investment’s assets will increase faster than if no leverage had been used. In the event of price falls, this leverage is outweighed by a more rapid decline in the investment’s assets.

| BondBloxx Private Credit CLO ETF | Derivatives Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives, such as swaps, forwards, and futures, involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage because leverage can exaggerate the effect of any increase or decrease in the value of securities and other instruments held by the Fund. Derivatives entail the risk that the counterparty will default on its payment obligations. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV.
|
|||||||||||||||||||||||||||||||
| BondBloxx Private Credit CLO ETF | Interest Rate Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Interest Rate Risk. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low, or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. The U.S. government and the U.S. Federal Reserve, as well as certain foreign governments and central banks, have from time to time taken steps to support financial markets. The U.S. government and the U.S. Federal Reserve may, conversely, reduce market support activities, including by taking action intended to increase certain interest rates. This and other government intervention may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. Changes in government activities in this regard, such as changes in interest rate policy, can negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests.
|
|||||||||||||||||||||||||||||||
| BondBloxx Private Credit CLO ETF | Newly Issued Securities Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Newly Issued Securities Risk. The credit obligations in which the Fund invests may include newly issued securities, or “new issues,” such as initial debt offerings. New issues may have a magnified impact on the performance of the Fund during periods in which it has a small asset base. The impact of new issues on the Fund’s performance likely will decrease as the Fund’s asset size increases, which could reduce the Fund’s returns. New issues may not be consistently available to the Fund for investing, particularly as the Fund’s asset base grows. Certain new issues, such as initial debt offerings, may be volatile in price due to the absence of a prior trading market, limited quantities available for trading and limited information about the issuer. The Fund may hold new issues for a short period of time. This may increase the Fund’s portfolio turnover and may lead to increased expenses for the Fund, such as transaction costs. In addition, new issues can experience an immediate drop in value after issuance if the demand for the securities does not continue to support the offering price.

| BondBloxx Private Credit CLO ETF | Extended Settlement Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Extended Settlement Risk. Newly issued CLOs purchased in the primary market typically experience delayed or extended settlement periods. In the period following such a purchase and prior to settlement these CLOs may be considered less liquid than similar CLOs available in the secondary market. In such circumstances the Fund bears a risk of loss if the value of the CLO declines before the settlement date or if the Fund is required to sell the CLO prior to settlement. There is also the risk that the security will not be issued or that the counterparty will not meet its obligation, resulting in a loss of the investment opportunity.

| BondBloxx Private Credit CLO ETF | Investment Focus Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investment Focus Risk. Because the Fund invests primarily in CLOs it is susceptible to an increased risk of loss due to adverse occurrences in the CLO market, generally, and in the various markets impacting the portfolios of loans underling these CLOs. The Fund’s CLO investment focus may cause the Fund to perform differently than the overall financial market and the Fund’s performance may be more volatile than if the Fund’s investments were more diversified across financial instruments and or markets.
|
|||||||||||||||||||||||||||||||
| BondBloxx Private Credit CLO ETF | Foreign Exposure Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Exposure Risk. The Fund may have exposure to foreign markets as a result of its investments in foreign securities and securities denominated in foreign currencies. As a result, its returns and NAV may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. To the extent the Fund invests in foreign debt securities, such investments are sensitive to changes in interest rates. The Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments.

| BondBloxx Private Credit CLO ETF | Inflation Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

| BondBloxx Private Credit CLO ETF | Cash Transaction Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cash Transaction Risk. Unlike other ETFs, the Fund expects to effect its creations and redemptions at least partially for cash, rather than wholly for in-kind securities, because of the nature of the Fund’s investments. Therefore, it may be required to sell portfolio securities and subsequently incur brokerage costs and/or recognize gains or losses on such sales that the Fund might not have recognized if it were to distribute portfolio securities in kind. As such, investments in the Fund’s shares may be less tax-efficient than an investment in a conventional ETF. In addition, Creation Unit redemptions for cash may cause the Fund to incur portfolio transaction fees or charges it would not otherwise incur with an in-kind redemption, to the extent such fees or charges are not offset by the redemption transaction fee paid by Authorized Participants (“APs”). In addition, the Fund’s use of cash transactions may result in wider bid-ask spreads in Fund shares trading in the secondary market as compared to ETFs that transact exclusively on an in-kind basis.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

| BondBloxx Private Credit CLO ETF | Infectious Illness Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the 1940 Act. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

| BondBloxx Private Credit CLO ETF | Authorized Participant Concentration Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

| BondBloxx Private Credit CLO ETF | Management Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Management Risk. The Fund is subject to management risk because it is an actively-managed ETF. The Sub-Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected. See also “Management—Manager of Managers Structure.”

| BondBloxx Private Credit CLO ETF | Portfolio Turnover Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Portfolio Turnover Risk. High portfolio turnover (considered by the Fund to mean higher than 100% annually) may result in increased transaction costs to the Fund or an Underlying Fund, including brokerage commissions, dealer mark-ups and other transaction costs on the sale of the securities and on reinvestment in other securities.

| BondBloxx Private Credit CLO ETF | Operational Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

| BondBloxx Private Credit CLO ETF | Valuation Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers. See also “Debt Securities Risk—Valuation Risk.”

| BondBloxx Private Credit CLO ETF | Cybersecurity Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, BIM, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of its service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

| BondBloxx Private Credit CLO ETF | Exchange Traded Fund And Other Investment Company Risk [Member] | |||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Exchange-Traded Fund and Other Investment Company Risk. The Fund may invest in shares of other investment companies and ETFs. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company or ETF when the Fund invests in shares of another investment company or ETF. The Fund is subject to the risks associated with the ETF or investment company’s investments. The price and movement of an ETF designed to track an index may not track the index and may result in a loss. In addition, ETFs may trade at a price above (premium) or below (discount) their net asset value, especially during periods of significant market volatility or stress, causing investors to pay significantly more or less than the value of the ETF’s underlying portfolio. Certain ETFs traded on exchanges may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer.
