Investment Risks - The Rebuild America ETF	Sep. 14, 2026
Equity Securities Risk Member
Prospectus [Line Items]
Risk [Text Block]	Equity Securities Risk. The risks that could affect the value of the Fund’s shares and the total return on your investment include the possibility that the equity securities held by the Fund will experience sudden, unpredictable drops in value or long periods of decline in value.
Concentration Risk Member
Prospectus [Line Items]
Risk [Text Block]	Concentration Risk. Because the Fund concentrates its investments in the infrastructure group of industries, the Fund’s performance will be more susceptible to economic, business, regulatory, political and other developments affecting the infrastructure group of industries. As a result the Fund may have greater volatility and may underperform the broader market.
Infrastructure Companies Risk Member
Prospectus [Line Items]
Risk [Text Block]	Infrastructure Companies Risk. The Fund primarily invests in securities related to U.S. infrastructure development, which includes issuers from the industrials, materials, energy, utilities, health care, information technology and communication services sectors. The Fund's performance will therefore be closely tied to the conditions and performance of issuers focused in infrastructure build out, and the Fund may be subject to greater price volatility and risk of loss than a fund with a broader investment mandate. Adverse developments affecting any aspect of infrastructure development, such as changes in government spending priorities, regulatory actions, supply chain disruptions, or commodity price fluctuations, may have a significant impact on the Fund’s performance.
Portfolio Turnover Risk Member
Prospectus [Line Items]
Risk [Text Block]	Portfolio Turnover Risk. The Fund's estimated annual portfolio turnover rate of 100% may result in higher transaction costs, which may negatively impact the Fund's performance. In addition, high portfolio turnover may generate short-term capital gains taxable to shareholders as ordinary income, which may reduce the Fund's after-tax performance.
Market Risk Member
Prospectus [Line Items]
Risk [Text Block]	Market Risk. Financial market risks affect the value of individual instruments in which the Fund invests. When the value of the Fund’s investments goes down, your investment in the Fund decreases in value and you could lose money. Factors such as economic growth and market conditions, interest rates, and political events affect the markets. Periods of market volatility may occur in response to market events and other economic, political, and global macro factors (for example, a global pandemic, government deficits and debt, military conflicts, inflation, tariffs, sanctions, and recessions). These and other similar events could be prolonged and could adversely affect the value and liquidity of the Fund’s investments and negatively impact the Fund’s performance. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected.
Management Risk Member
Prospectus [Line Items]
Risk [Text Block]	Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Sub-Advisor’s success or failure to implement investment strategies for the Fund. Investment decisions made by the Sub-Advisor in implementing these investment strategies may not produce the returns expected by the Sub-Advisor, may cause the Fund’s shares to lose value or may cause the Fund to underperform other funds with similar investment objectives. The Sub-Advisor may be incorrect in its assessment of the pricing discrepancies or prices may not move in the manner anticipated by the Sub-Advisor.
Market Capitalization Risk Member
Prospectus [Line Items]
Risk [Text Block]	Market Capitalization Risk. The Fund may hold securities of any market capitalization and may be subject to large-capitalization investing risk, mid-capitalization investing risk and/or small-capitalization investing risk. ▪Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and, therefore subject to slower growth during times of economic expansion. ▪Mid-Capitalization Investing. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole. ▪Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies.

Prospectus [Line Items]
Risk [Text Block]	Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies.
New Fund Risk Member
Prospectus [Line Items]
Risk [Text Block]	New Fund Risk. The Fund is recently organized with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision. There can be no assurance that the Fund will grow to or maintain an economically viable size.
ETF Risks Member
Prospectus [Line Items]
Risk [Text Block]	ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, it is exposed to the following risks: ▪Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent that (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs 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 such functions, Fund shares may trade at a material discount to NAV, the bid-ask spread could widen, and shares could face trading halts and/or delisting. ▪Costs of Buying or Selling Fund Shares. Due to the costs of buying or selling shares, including brokerage commissions imposed by brokers, frequent trading of shares may significantly reduce investment results and an investment in shares may not be advisable for investors who anticipate regularly making small investments. ▪Shares May Trade at Prices Other Than NAV. As with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund shares will approximate the Fund’s NAV, there may be times when the market price of Fund shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Fund shares or during periods of market volatility. If an investor buys Fund shares when the shares’ market price is at a premium, the investor may pay more than the shares’ underlying value. If an investor sells Fund shares when the shares’ market price is at a discount, the investor may receive less than the shares’ underlying value. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Fund shares in the secondary market, in which case such premiums or discounts may be significant. ▪Trading. Although shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market will be maintained for Fund shares or that Fund shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund shares and could lead to differences between the market price of the Fund’s shares and the underlying value of those shares. These conditions could cause the Fund’s shares to trade at a material discount to NAV and the bid-ask spread to widen.

Model And Data Risk Member
Prospectus [Line Items]
Risk [Text Block]	Model and Data Risk. The Sub-Advisor relies on its proprietary model in making investment decisions for the Fund. When the model and/or the data the model relies upon prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential loss.
Depositary Receipt Risk Member
Prospectus [Line Items]
Risk [Text Block]	Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.
Foreign Securities Risk Member
Prospectus [Line Items]
Risk [Text Block]	Foreign Securities Risk. Foreign securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. Foreign securities could be affected by factors not present in the United States, including expropriation, confiscation of property, and difficulties in enforcing contracts. Compared to U.S. companies, there generally is less publicly available information about foreign companies and there may be less governmental regulation and supervision of foreign companies. Foreign securities generally experience more volatility than their domestic counterparts. Depositary receipts may have additional risks, including creditworthiness of the depositary bank and the risk of an illiquid market. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Fluctuations in the exchange rates between the U.S. dollar and foreign currencies, currency exchange control regulations, and restrictions or prohibitions on the repatriation of foreign currencies may negatively affect an investment.
Tax Risk Member
Prospectus [Line Items]
Risk [Text Block]	Tax Risk. In order to qualify for the favorable tax treatment generally available to a regulated investment company (“RIC”), the Fund must satisfy certain diversification requirements under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). In particular, the Fund must generally diversify its holdings so that, in part, at the end of each quarter of each taxable year, at least 50% of the value of the Fund’s total assets is represented by (1) cash and cash items, U.S. government securities, securities of other RICs, and (2) other securities, with such other securities limited, in respect of any one issuer, to an amount not greater than 5% of the value of the Fund’s total assets and to not more than 10% of the outstanding voting securities of such issuer. The Fund’s efforts to satisfy the diversification requirement may affect the Fund’s execution of its investment strategy. If the Fund were to fail to meet the tests and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency.
Risk Nondiversified Status [Member]
Prospectus [Line Items]
Risk [Text Block]	Non-Diversification Risk. A non-diversified fund under the federal securities laws may hold a significant percentage of its assets in the securities of relatively fewer companies or even one company; therefore, events affecting those companies have a greater impact on the Fund than on a diversified fund.
