Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund 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 Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year ended November 30, 2023, the Fund’s portfolio turnover rate was 7% of its average portfolio value.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Fund will invest at least 80% of its net assets plus the amount of any borrowings for investment purposes in securities of energy infrastructure companies. Energy infrastructure companies are companies that process, store, transport and market natural gas, natural gas liquids, refined products and crude oil (i.e., midstream infrastructure) as well as generate, transport and distribute electricity (i.e., power & renewable infrastructure).  The Fund intends to focus its investments primarily in equity securities of midstream infrastructure and also may invest in midstream master limited partnerships (“MLPs”) and power and renewable infrastructure. MLPs, also known as publicly traded partnerships, predominately operate, or directly or indirectly own, energy-related assets. For purposes of this strategy, energy infrastructure companies include investment companies that invest primarily in energy infrastructure companies. The Fund is non-diversified.
The Fund seeks to achieve its investment objective by investing primarily in equity securities of any market capitalization that are publicly traded on an exchange or in the over-the-counter market, consisting of common stock, but also including, among others, MLP and limited liability company (“LLC”) common units; the equity securities issued by MLP affiliates, such as common shares of corporations that own, directly or indirectly, MLP general partner interests; and other investment companies that invest in energy infrastructure companies.
MLP common units represent an equity ownership interest in an MLP. Some energy infrastructure companies in which the Fund may invest are organized as LLCs which are treated in the same manner as MLPs for federal income tax purposes. The Fund may invest in LLC common units which represent an ownership interest in the LLC. Interests in MLP and LLC common units entitle the holder to a share of the company’s success through distributions and/or capital appreciation.
Pursuant to tax regulations, the Fund may invest no more than 25% of its total assets in the securities of MLPs and other entities treated as qualified publicly traded partnerships.
In addition, the Fund may invest in preferred equity, and convertible securities.
Under normal circumstances, the Fund may invest up to: (i) 30% of its total assets in securities denominated in the currency of a non-North American country, which may include securities issued by energy companies organized and/or having securities traded on an exchange outside North America and/or securities of other non-North American companies that are denominated in the currency of a non-North American country; (ii) 20% of its total assets in debt securities of any issuer, including securities which may be rated below investment grade (“junk bonds”) by a nationally recognized statistical rating organization (“NRSRO”) or judged by Tortoise Capital Advisors, L.L.C., also doing business as TCA Advisors ("TCA Advisors" or the "Adviser"), to be of comparable credit quality; (iii) 15% of its net assets in illiquid investments; and (iv) 10% of its total assets in securities of any issuer. The Fund may invest in initial public offerings (“IPOs”). The Fund may invest in other investment companies to the extent permitted by the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund may invest in permissible securities without regard to the market capitalization of the issuer of such security. The Fund will not have any duration or weighted average maturity restrictions.
Except for investments in illiquid investments, the above investment restrictions apply at the time of purchase, and the Fund will not be required to reduce a position due solely to market value fluctuations in order to comply with these restrictions. To the extent that market value fluctuations cause illiquid investments held by the Fund to exceed 15% of its net assets, the Fund will determine how to remediate the excess illiquid investments in accordance with the 1940 Act and the Fund's policies and procedures.
Tortoise Capital Advisors, L.L.C. also doing business as TCA Advisors, ("TCA Advisors" or the "Adviser") seeks to invest the Fund in securities that offer a combination of yield, growth and quality, intended to result in attractive long-term total returns. The Adviser’s securities selection process includes a comparison of quantitative, qualitative and relative value factors. Primary emphasis will be placed on proprietary models constructed and maintained by the Adviser’s in-house investment team, although the Adviser may use research provided by broker-dealers and investment firms. To determine whether a company meets its criteria, the Adviser will generally look for long-lived energy infrastructure companies with essential assets with long economic lives (generally 20 years or more), high barriers to entry, total return potential, predictable revenue and stable operating structures, and experienced, operations-focused management teams.

Tortoise Energy Infrastructure Total Return Fund | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Non-Diversified Fund Risk. Because the Fund is “non-diversified” and may invest a greater percentage of its assets in the securities of a single issuer, a decline in the value of an investment in a single issuer could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.
Tortoise Energy Infrastructure Total Return Fund | Risk Lose Money [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Remember, in addition to possibly not achieving your investment goals, you could lose all or a portion of your investment in the Fund over short or even long periods of time.
Tortoise Energy Infrastructure Total Return Fund | Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other governmental agency.
Tortoise Energy Infrastructure Total Return Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
General Market Risk.  The Fund is subject to all of the business risks and uncertainties associated with any mutual fund, including the risk that it will not achieve its investment objective and that the value of an investment in its securities could decline substantially and cause you to lose some or all of your investment. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities in the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.
Tortoise Energy Infrastructure Total Return Fund | Adviser Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Adviser Risk.  The Fund may not meet its investment objective or may underperform the market or other mutual funds with similar strategies if the Adviser cannot successfully implement the Fund’s investment strategies.
Tortoise Energy Infrastructure Total Return Fund | Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Concentration Risk.  The Fund’s strategy of focusing its investments in MLPs and pipeline companies means that the performance of the Fund will be closely tied to the performance of the energy 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.
Tortoise Energy Infrastructure Total Return Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Equity Securities Risk.  Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors, geographic markets, the equity securities of energy infrastructure companies in particular, or a particular company in which the Fund invests.
Tortoise Energy Infrastructure Total Return Fund | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Foreign Securities Risk.  Investments in securities of foreign companies involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies.
Tortoise Energy Infrastructure Total Return Fund | Currency Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Currency Risk. When the Fund buys or sells securities on a foreign stock exchange, the transaction is undertaken in the local currency rather than in U.S. dollars, which carries the risk that the value of the foreign currency will increase or decrease, which may impact the value of the Fund’s portfolio holdings and your investment. Foreign countries may adopt economic policies and/or currency exchange controls that affect its currency valuations in a disadvantageous manner for U.S. investors and companies and restrict or prohibit the Fund’s ability to repatriate both investment capital and income, which could place the Fund’s assets in such country at risk of total loss.
Tortoise Energy Infrastructure Total Return Fund | MLP Risk member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
MLP Risk.  MLPs are subject to many risks, including those that differ from the risks involved in an investment in the common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership and are exposed to a remote possibility of liability for all of the obligations of that MLP. Holders of MLP units are also exposed to the risk that they will be required to repay amounts to the MLP that are wrongfully distributed to them. In addition, the value of the Fund’s investment in an MLP will depend largely on the MLP’s treatment as a partnership for U.S. federal income tax purposes. Furthermore, MLP interests may not be as liquid as other more commonly traded equity securities.
Tortoise Energy Infrastructure Total Return Fund | MLP Affiliate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
MLP Affiliate Risk. The performance of securities issued by MLP affiliates, including common shares of corporations that own general partner interests, primarily depends on the performance of an MLP. The risks and uncertainties that affect the MLP, its operational results, financial condition, cash flows and distributions also affect the value of securities held by that MLP’s affiliate.
Tortoise Energy Infrastructure Total Return Fund | Capital Markets Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Capital Markets Risk.  MLPs normally pay out the majority of their operating cash flows to partners. Therefore, MLPs and other issuers in which the Fund invests may rely significantly on capital markets for access to equity and debt financing in order to fund organic growth projects and acquisitions. Should market conditions limit issuers’ access to capital markets, their distribution growth prospects could be at risk.
Tortoise Energy Infrastructure Total Return Fund | Debt Securities Risks Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Debt Securities Risks. Investments in fixed income securities will be subject to credit risk, interest rate risk and prepayment risk. Credit risk is the risk that an issuer will default or fail to pay principal and interest when due. Interest rate risk is the risk that the value of fixed income securities fluctuates with changes in interest rates (e.g., increases in interest rates result in a decrease in value of fixed income securities). The Fund will be exposed to heightened interest rate risk as interest rates rise from historically low levels. Pre-payment risk is the risk that the principal on fixed income securities will be paid off prior to maturity causing the Fund to invest in fixed income securities with lower interest rates. Duration risk is the risk that holding long duration and long maturity investments will magnify certain other risks, including interest rate risk and credit risk.
Tortoise Energy Infrastructure Total Return Fund | Below Investment Grade Debt Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Below Investment Grade Debt Securities Risk. Investments in below investment grade debt securities and unrated securities of similar credit quality as determined by the Adviser (commonly known as “junk bonds”) involve a greater risk of default and are subject to greater levels of credit and liquidity risk. Below investment grade debt securities have speculative characteristics and their value may be subject to greater fluctuation than investment grade debt securities.
Tortoise Energy Infrastructure Total Return Fund | Large Cap Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Large Cap Company Risk. The Fund’s investments in larger, more established companies are subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.  Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in consumer tastes or innovative smaller competitors potentially resulting in lower markets for their common stock.
Tortoise Energy Infrastructure Total Return Fund | Mid Cap And Small Cap Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Mid Cap and Small Cap Companies Risk. The mid cap and small cap companies may not have the management experience, financial resources, product or business diversification and competitive strengths of large cap companies. Therefore, these securities may have more price volatility and be less liquid than the securities of larger, more established companies.
Tortoise Energy Infrastructure Total Return Fund | Investment Company And RIC Compliance Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Investment Company and RIC Compliance Risk. The Fund may be subject to increased expenses and reduced performance as a result of its investments in other investment companies and MLPs. When investing in other investment companies, the Fund bears its pro rata share of the other investment company’s fees and expenses including the duplication of advisory and other fees and expenses. The Fund’s investment in MLPs presents unusual challenges in qualifying each year as a “regulated investment company” (a “RIC”) under the Internal Revenue Code, a designation which allows the Fund to avoid paying taxes at regular corporate rates on its income. If 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.
Tortoise Energy Infrastructure Total Return Fund | IPO Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
IPO Risk.  The market value of IPO shares will 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 the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk.
Tortoise Energy Infrastructure Total Return Fund | Cybersecurity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Cybersecurity Risk. Investment advisers, including the Adviser, must rely in part on digital and network technologies (collectively “cyber networks”) to conduct their businesses. Such cyber networks might in some circumstances be at risk of cyber-attacks that could potentially seek unauthorized access to digital systems for purposes such as misappropriating sensitive information, corrupting data, or causing operational disruption.
Tortoise Energy Infrastructure Total Return Fund | Illiquid Investments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Illiquid Investments Risk.  The Fund may be exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular securities at an advantageous price or in a timely manner. Illiquid investments may include restricted securities that cannot be sold immediately because of statutory and contractual restrictions on resale.
Tortoise Energy Infrastructure Total Return Fund | Energy Infrastructure Industry Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
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 and/or operating pipelines, gathering and processing assets, power infrastructure, propane assets, as well as capital markets, terrorism, natural disasters, climate change, operating, regulatory, environmental, supply and demand, and price volatility risks.
Tortoise Energy Infrastructure Total Return Fund | Energy Industry Risk Member

Risk [Text Block] rr_RiskTextBlock
Energy Industry Risk. Companies in the energy 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 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 pipelines, gathering and processing energy assets; 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.
Tortoise Energy Infrastructure Total Return Fund | Convertible Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Convertible Securities Risk.  Convertible securities are hybrid securities that have characteristics of both bonds and common stocks and are therefore subject to both debt security risks and equity risk.  Convertible securities are subject to equity risk especially when their conversion value is greater than the interest and principal value of the bond.  The prices of equity securities may rise or fall because of economic or political changes and may decline over short or extended periods of time.
Tortoise Energy Infrastructure Total Return Fund | Preferred Stock Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Preferred Stock Risk.  A preferred stock is a blend of the characteristics of a bond and common stock.  It may offer a higher yield than common stock and has priority over common stock in equity ownership, but it does not have the seniority of a bond and, unlike common stock, its participation in the issuer’s growth may be limited.  Although the dividend on a preferred stock may be set at a fixed annual rate, in some circumstances it may be changed or passed by the issuer.  Preferred stock generally does not confer voting rights.
Tortoise Energy Infrastructure Total Return Fund | Tax Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Tax Risk. The Fund has elected to be, and intends to qualify each year for treatment as, a “regulated investment company” under the U.S. Internal Revenue Code of 1986, as amended (the “Code”). To maintain qualification for federal income tax purposes as a regulated investment company under the Code, the Fund must meet certain source-of-income, asset diversification and annual distribution requirements, as discussed in detail below under “Tax Consequences.”

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Fund will invest at least 80% of its total assets in equity and debt securities of other companies focused in the energy infrastructure sector and in equity and debt securities of master limited partnerships (“MLPs”) focused in the energy infrastructure sector. Companies focused in the energy infrastructure sector include MLP parent companies and other MLP affiliates (together with MLPs, “MLP Entities”), which may invest their assets in varying degrees in MLPs. Some of these parent companies and other affiliates primarily own equity interests in MLPs, while others may jointly own assets with MLPs, and still others may only invest small portions of their assets in equity interests of MLPs. The Adviser considers the energy infrastructure sector to be comprised of companies that engage in one or more aspects of exploration, production, gathering, processing, refining, transmission, marketing, storage and delivery of energy products such as natural gas, natural gas liquids (including propane), crude oil, refined petroleum products or coal; oilfield services, including drilling, cementing and stimulations; the generation, transmission and distribution of electricity; water and wastewater treatment, distribution and disposal; or the generation, transportation and sale of alternative, non-fossil fuel based energy sources including, but not limited to, biodiesel, ethanol, biomass, geothermal, hydroelectric, nuclear, solar or wind energy. The Adviser considers a company to be focused in the energy infrastructure sector if at least 50% of the company’s assets are utilized in one or more of these activities. The Fund will also invest in MLP Entities and other companies operating in the natural resources sector, which includes companies principally engaged in owning or developing non-energy natural resources (including timber and minerals) and industrial materials, or supplying goods or services to such companies.
In addition to making direct investments in MLP equity units, the Adviser intends to invest the Fund’s remaining assets in such a way as to provide, in total, a high level of correlation with MLP equities. These other investments may include equity and debt securities of entities that own interests in MLPs or assets owned in common with MLPs. The Fund will also invest in securities of entities that operate in industries similar to MLPs, such as energy infrastructure, even though such entities have no direct affiliation with an MLP.
The Fund will purchase securities across the capital structure of MLP Entities, including equity and debt securities of MLPs and their affiliates. The Fund may invest in equity securities of MLP Entities and other issuers without regard for their market capitalizations.
The Adviser intends to allocate the Fund’s assets towards the mix of equity and debt securities it deems appropriate based upon its view of economic, market, and political conditions. As a result of this asset allocation the Fund’s portfolio may, at times, be significantly invested in either equity or debt securities, or both. The Fund’s investment in equity securities may include both common and preferred stock. The Fund’s investment in debt securities may include both investment grade debt securities and high yield debt securities (often called “junk bonds”), which are securities rated below investment grade (that is, rated Ba or lower by Moody’s Investors Service, Inc. (“Moody’s”) or BB or lower by Standard & Poor’s Ratings Group (“S&P”), comparably rated by another statistical rating organization, or, if unrated, determined by the Adviser to be of comparable credit quality). The Fund will only purchase debt securities which, at the time of acquisition, are rated at least B3 by Moody’s or B- by S&P or are comparably rated by another statistical rating organization, or, if unrated, are determined by the Adviser to be of comparable credit quality. The Fund may invest in debt securities of any maturity.
The Fund may invest in foreign securities and U.S. dollar denominated foreign issuers. Such investments in securities of foreign issuers may include sponsored or unsponsored American Depository Receipts (“ADRs”) and Yankee bonds. ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. Yankee bonds are bonds denominated in U.S. dollars that are publicly issued in the United States by foreign banks and corporations.
In certain market environments, the Fund may, but is not required to, use various hedging techniques, such as the buying and selling of options, including covered call options, to seek to mitigate one or more risks associated with investments in MLPs and energy infrastructure assets including market risk and interest rate risk, which, among other factors, could adversely affect market valuations of specific securities or certain sectors of the energy MLP and energy infrastructure market place, or the Fund’s overall portfolio.
The Fund may invest up to 15% of its net assets in securities that are not registered under the Securities Act of 1933 or that otherwise may not be sold in public offerings, which are commonly known as “restricted” securities. The Fund will typically acquire restricted securities in directly negotiated transactions.
The Fund may invest in initial public offerings (“IPOs”), other investment companies including exchange-traded funds (“ETFs”), and exchange-traded notes (“ETNs”). ETFs are investment companies that generally seek to track the performance of specific indices, shares of which are traded on exchanges. The Fund will include ETFs that primarily invest in MLPs and/or other companies focused in the energy infrastructure sector for purposes of satisfying the Fund’s investment strategy of investing at least 80% of its total assets in equity and debt securities of MLPs focused in the energy infrastructure sector, and in equity and debt securities of other companies focused in the energy infrastructure sector. ETNs are unsecured debt securities issued by a bank that are linked to the total return of a market index.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
General Market Risk.  The Fund is subject to all of the business risks and uncertainties associated with any mutual fund, including the risk that it will not achieve its investment objective and that the value of an investment in its securities could decline substantially and cause you to lose some or all of your investment. The Fund’s net asset value (“NAV”) and
investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities in the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.
Tortoise Energy Infrastructure and Income Fund | Energy And Natural Resource Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Energy and Natural Resource Company Risk.  Under normal circumstances, the Fund concentrates its investments in the energy infrastructure sector and may invest a significant portion of its assets in the natural resources sector of the economy, which includes a number of risks, including the following: supply and demand risk, depletion and exploration risk, marine transportation companies risk, regulatory risk, commodity pricing risk, weather risk, cash flow risk, affiliated party risk, catastrophe risk, acquisition risk, and natural resources sector risk. For example, decreases in oil prices may have a substantial impact on the prices of publicly-traded equity securities of energy infrastructure companies. The Fund considers the following industries as making up the energy infrastructure sector: energy, materials, transportation and utilities.
Tortoise Energy Infrastructure and Income Fund | Adviser Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Adviser Risk.  The Fund may not meet its investment objective or may underperform the market or other mutual funds with similar strategies if the Adviser cannot successfully implement the Fund’s investment strategies.
Tortoise Energy Infrastructure and Income Fund | Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Concentration Risk. The Fund’s strategy of focusing its investments in energy infrastructure companies means that the performance of the Fund will be closely tied to the performance of the energy 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.
Tortoise Energy Infrastructure and Income Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Equity Securities Risk.  Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors, geographic markets, the equity securities of energy infrastructure companies in particular, or a particular company in which the Fund invests.
Tortoise Energy Infrastructure and Income Fund | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Securities Risk.  Investments in securities of foreign companies involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies.
Tortoise Energy Infrastructure and Income Fund | Currency Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Currency Risk. When the Fund buys or sells securities on a foreign stock exchange, the transaction is undertaken in the local currency rather than in U.S. dollars, which carries the risk that the value of the foreign currency will increase or decrease, which may impact the value of the Fund’s portfolio holdings and your investment. Foreign countries may adopt economic policies and/or currency exchange controls that affect its currency valuations in a disadvantageous manner for U.S. investors and companies and restrict or prohibit the Fund’s ability to repatriate both investment capital and income, which could place the Fund’s assets in such country at risk of total loss.
Tortoise Energy Infrastructure and Income Fund | ADR Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock ADR Risk. ADRs are generally subject to the same risks as the foreign securities because their values depend on the performance of the underlying foreign securities. ADRs may be purchased through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the depositary security. Holders of unsponsored ADRs generally bear all the costs of such depositary receipts, and the issuers of unsponsored ADRs frequently are under no obligation to distribute shareholder communications received from the company that issues the underlying foreign securities or to pass through voting rights to the holders of the ADRs. As a result, there may not be a correlation between such information and the market values of unsponsored ADRs.
Tortoise Energy Infrastructure and Income Fund | Hedging Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
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. There can be no assurance that the Fund’s hedging strategies will be effective or that hedging transactions will be available to the Fund. The Fund is not required to engage in hedging transactions at any given time or from time to time, even under volatile market environment and the Fund may choose not to do so from time to time.
Tortoise Energy Infrastructure and Income Fund | Interest Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Interest Rate Risk. MLPs and other higher yield securities historically have shown sensitivity to interest rate movements. In an increasing interest rate environment, these types of securities may experience upward pressure on their yields in order to stay competitive with other interest rate sensitive securities. Also, significant portions of the market value of MLPs and other higher yield securities may be based upon their current yields. Accordingly, the prices of these securities may be sensitive to fluctuations in interest rates and may decline when interest rates rise.
Tortoise Energy Infrastructure and Income Fund | MLP Risk member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock MLP Risk.  MLPs are subject to many risks, including those that differ from the risks involved in an investment in the common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership and are exposed to a remote possibility of liability for all of the obligations of that MLP. Holders of MLP units are also exposed to the risk that they will be required to repay amounts to the MLP that are wrongfully distributed to them. In addition, the value of the Fund’s investment in an MLP will depend largely on the MLP’s treatment as a partnership for U.S. federal income tax purposes. Furthermore, MLP interests may not be as liquid as other more commonly traded equity securities.
Tortoise Energy Infrastructure and Income Fund | MLP Affiliate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
MLP Affiliate Risk. The performance of securities issued by MLP affiliates, including common shares of corporations that own general partner interests, primarily depends on the performance of an MLP. The risks and uncertainties that affect the MLP, its operational results, financial condition, cash flows and distributions also affect the value of securities held by that MLP’s affiliate.
Tortoise Energy Infrastructure and Income Fund | Debt Securities Risks Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Debt Securities Risks. Investments in fixed income securities will be subject to credit risk, interest rate risk and prepayment risk. Credit risk is the risk that an issuer will default or fail to pay principal and interest when due. Interest rate risk is the risk that the value of fixed income securities fluctuates with changes in interest rates (e.g., increases in interest rates result in a decrease in value of fixed income securities). The Fund will be exposed to heightened interest rate risk as interest rates rise from historically low levels. Pre-payment risk is the risk that the principal on fixed income securities will be paid off prior to maturity causing the Fund to invest in fixed income securities with lower interest rates. Duration risk is the risk that holding long duration and long maturity investments will magnify certain other risks, including interest rate risk and credit risk.
Tortoise Energy Infrastructure and Income Fund | Below Investment Grade Debt Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Below Investment Grade Debt Securities Risk. Investments in below investment grade debt securities and unrated securities of similar credit quality as determined by the Adviser (commonly known as “junk bonds”) involve a greater risk of default and are subject to greater levels of credit and liquidity risk. Below investment grade debt securities have speculative characteristics and their value may be subject to greater fluctuation than investment grade debt securities.
Tortoise Energy Infrastructure and Income Fund | Capital Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Capital Markets Risk.  MLPs normally pay out the majority of their operating cash flows to partners. Therefore, MLPs and other issuers in which the Fund invests may rely significantly on capital markets for access to equity and debt financing in order to fund organic growth projects and acquisitions. Should market conditions limit issuers’ access to capital markets, their distribution growth prospects could be at risk.
Tortoise Energy Infrastructure and Income Fund | Counterparty Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Counterparty Risk.  Counterparty risk is the risk that the other party or parties to an agreement or a participant to a transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or failing to fulfill the obligations of the contract or transaction.
Tortoise Energy Infrastructure and Income Fund | Credit Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Credit Risk.  If an issuer or guarantor of a debt security held by the Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Fund’s portfolio will typically decline.
Tortoise Energy Infrastructure and Income Fund | Mid Cap And Small Cap Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Mid Cap and Small Cap Companies Risk. The mid cap and small cap companies may not have the management experience, financial resources, product or business diversification and competitive strengths of large cap companies. Therefore, these securities may have more price volatility and be less liquid than the securities of larger, more established companies.
Tortoise Energy Infrastructure and Income Fund | Investment Company And RIC Compliance Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Investment Company and RIC Compliance Risk. The Fund may be subject to increased expenses and reduced performance as a result of its investments in other investment companies. When investing in other investment companies, the Fund bears its pro rata share of the other investment company’s fees and expenses including the duplication of advisory and other fees and expenses. If for any taxable year the Fund fails to qualify as a “regulated investment company” (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.
Tortoise Energy Infrastructure and Income Fund | ETF Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
ETF Risk. Investing in an ETF will provide the Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.
Tortoise Energy Infrastructure and Income Fund | ETN Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
ETN Risk. ETNs are debt securities that combine certain aspects of ETFs and bonds. ETNs are not investment companies and thus are not regulated under the 1940 Act. ETNs, like ETFs, are traded on stock exchanges and generally track specified market indices, and their value depends on the performance of the underlying index and the credit rating of the issuer. ETNs may be held to maturity, but unlike bonds there are no periodic interest payments and principal is not protected.
Tortoise Energy Infrastructure and Income Fund | IPO Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
IPO Risk.  The market value of IPO shares will 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 the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk.
Tortoise Energy Infrastructure and Income Fund | Leverage Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Leverage Risk. Certain transactions, including the use of derivatives, may give rise to a form of leverage. To mitigate leveraging risk, the Fund’s custodian will segregate or identify liquid assets or otherwise cover the transactions that may give rise to such risk. Leveraging may cause the Fund to liquidate portfolio positions to satisfy its obligations or to meet segregation requirements when it may not be advantageous to do so. Leveraging may cause the Fund to be more volatile than if the Fund had not been leveraged.

Risk [Text Block] rr_RiskTextBlock Cybersecurity Risk. Investment advisers, including the Adviser, must rely in part on digital and network technologies (collectively “cyber networks”) to conduct their businesses. Such cyber networks might in some circumstances be at risk of cyber-attacks that could potentially seek unauthorized access to digital systems for purposes such as misappropriating sensitive information, corrupting data, or causing operational disruption.
Tortoise Energy Infrastructure and Income Fund | Derivatives Risk Member

Risk [Text Block] rr_RiskTextBlock
Derivatives Risk.  Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. The use of derivatives could increase or decrease the Fund’s exposure to the risks of the underlying instrument. Using derivatives can have a leveraging effect and increase fund volatility. A small investment in derivatives could have a potentially large impact on the Fund’s performance. Derivatives transactions can be highly illiquid and difficult to unwind or value, and changes in the value of a derivative held by the Fund may not correlate with the value of the underlying instrument or the Fund’s other investments. Many of the risks applicable to trading the instruments underlying derivatives are also applicable to derivatives trading. However, additional risks are associated with derivatives trading that are possibly greater than the risks associated with investing directly in the underlying instruments. These additional risks include, but are not limited to, illiquidity risk and counterparty credit risk. For derivatives that are required to be cleared by a regulated clearinghouse, other risks may arise from the Fund’s relationship with a brokerage firm through which it submits derivatives trades for clearing, including in some cases from other clearing customers of the brokerage firm. The Fund would also be exposed to counterparty risk with respect to the clearinghouse. Financial reform laws have changed many aspects of financial regulation applicable to derivatives. Once implemented, new regulations, including margin, clearing, and trade execution requirements, may make derivatives more costly, may limit their availability, may present different risks or may otherwise adversely affect the value or performance of these instruments. The extent and impact of these regulations are not yet fully known and may not be known for some time.

Risk [Text Block] rr_RiskTextBlock
Covered Call Option Risk. If the Fund writes a covered call option, during the option’s life the Fund gives up the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but retains the risk of loss should the price of the underlying security decline. Moreover, the writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option.
Tortoise Energy Infrastructure and Income Fund | Illiquid Investments Risk Member

Risk [Text Block] rr_RiskTextBlock
Illiquid Investments Risk. The Fund may be exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular securities or close call option positions at an advantageous price or in a timely manner. Illiquid investments may include restricted securities that cannot be sold immediately because of statutory and contractual restrictions on resale.
Tortoise Energy Infrastructure and Income Fund | Liquidity Risk Member

Risk [Text Block] rr_RiskTextBlock
Liquidity Risk. The Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Fund’s investments. Illiquid assets may also be difficult to value.

Risk [Text Block] rr_RiskTextBlock
Preferred Stock Risk.  A preferred stock is a blend of the characteristics of a bond and common stock.  It may offer a higher yield than common stock and has priority over common stock in equity ownership, but it does not have the seniority of a bond and, unlike common stock, its participation in the issuer’s growth may be limited.  Although the dividend on a preferred stock may be set at a fixed annual rate, in some circumstances it may be changed or passed by the issuer.  Preferred stock generally does not confer voting rights.
