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 mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 85% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example shows costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in securities issued by infrastructure companies. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy. The Fund expects to invest primarily in equity securities of companies located in a number of different countries, including the United States. The sub-adviser (“Sub-Adviser”) defines an infrastructure company as a company that derives at least 50% of its revenues or profits from, or devotes at least 50% of its assets to, the ownership, management, development, construction, renovation, enhancement, or operation of infrastructure assets or the provision of services to companies engaged in such activities. Examples of infrastructure assets include transportation assets (such as toll roads, bridges, railroads, airports, and seaports), utility assets (such as electric transmission and distribution lines, gas distribution pipelines, water pipelines and treatment facilities, and sewer facilities), energy assets (such as oil and gas pipelines, storage facilities, and other facilities used for the gathering, processing, or transporting hydrocarbon products), and communications assets (such as communications towers and satellites). Under normal circumstances, the Fund invests primarily in common stock, but may also invest in other equity securities including preferred stocks, convertible securities, rights or warrants to buy common stocks, and depositary receipts with characteristics similar to common stock. The Fund may also invest up to 25% of its net assets in master limited partnerships. The Fund may invest up to 30% of its assets in securities of companies located or doing business in emerging markets. The Fund’s investments may be denominated in U.S. dollars, non-U.S. currencies, or multinational currency units. The Fund may, but will not necessarily, hedge its currency exposure to securities denominated in non-U.S. currencies. The Fund may invest in securities of companies of any market size. The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”). The Sub-Adviser uses a multi-step investment process for constructing the Fund’s investment portfolio that combines top-down geographic region and infrastructure sector allocation with bottom-up individual stock selection. The Sub-Adviser first selects infrastructure sectors in certain geographic regions in which to invest, and determines the degree of representation in the portfolio of such sectors and regions, through a systematic evaluation of the regulatory environment and economic outlook, capital market trends, macroeconomic conditions, and the relative value of infrastructure sectors. The Sub-Adviser then uses an in-house valuation process to identify infrastructure companies whose risk-adjusted returns it believes are compelling relative to their peers. The Sub-Adviser’s in-house valuation process examines several factors, including the company’s management and strategy, the stability and growth potential of cash flows and dividends, the location of the company’s assets, the regulatory environment in which the company operates and the company’s capital structure. The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others. The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1⁄3% of its total assets.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds. Company: The price of a company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, reduced demand for company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless. Concentration: As a result of the Fund “concentrating,” as that term is defined in the 1940 Act, its assets in securities related to a particular industry or group of industries, the Fund may be subject to greater market fluctuations than a fund that is more broadly invested across industries. Financial, economic, business, and other developments affecting issuers in a particular industry or group of industries will have a greater effect on the Fund, and if securities of the particular industry or group of industries as a group fall out of favor, the Fund could underperform, or its net asset value may be more volatile than, funds that have greater industry diversification. Convertible Securities: Convertible securities are securities that are convertible into or exercisable for common stocks at a stated price or rate. Convertible securities are subject to the usual risks associated with debt instruments, such as interest rate and credit risk. In addition, because convertible securities react to changes in the value of the stocks into which they convert, they are subject to market risk. Currency: To the extent that the Fund invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Fund through foreign currency exchange transactions. Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Fund. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Fund and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. When used as an alternative or substitute for direct cash investments, the return provided by the derivative may not provide the same return as direct cash investment. In addition, given their complexity, derivatives expose the Fund to the risk of improper valuation. Foreign Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets. Infrastructure Companies: Infrastructure companies are subject to the risks of adverse economic, regulatory, political, legal, demographic, environmental, and other developments affecting the success of project they operate or finance. Infrastructure companies may be adversely affected by, among other things, high interest costs related to capital construction programs, costs associated with environmental and other regulations, difficulty in raising adequate capital on reasonable terms, the effect of economic slowdown, surplus capacity, increased competition, uncertainties concerning the availability of fuel at reasonable prices, and the effects of energy conservation policies, among other factors. Investment Model: A manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors. Liquidity: If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Fund to the risk that the price at which it sells illiquid securities will be less than the price at which they were valued when held by the Fund. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund. Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the Fund to achieve its investment objectives. Market Capitalization: Stocks fall into three broad market capitalization categories - large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-sized companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in larger companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with larger companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns. Master Limited Partnership: Master Limited Partnerships (“MLPs”) are limited partnerships in which ownership interests are publicly traded. MLPs often own or own interests in properties or businesses that are related to oil and gas industries, including pipelines. MLP may also invest in other types of investments, including credit-related investments. Investments held by MLPs may be illiquid. Certain MLP units may trade infrequently and in limited volume and may be subject to more abrupt or erratic price movements than securities of larger or more broadly based companies. Investments in MLPs may adversely affect the ability of the Fund to qualify for special tax treatment as a regulated investment company. Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Fund. The investment policies of the other investment companies may not be the same as those of the Fund; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Fund is typically subject. Securities Lending: Securities lending involves two primary risks: “investment risk” and “borrower default risk.” When lending securities, the Fund will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Fund to be more volatile. The use of leverage may increase expenses and increase the impact of the Fund’s other risks. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	PERFORMANCE INFORMATION
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows the changes in the Fund's performance from year to year, and the table compares the Fund's performance to the performance of a broad-based securities market index/indices for the same period. The Fund's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund's Class A shares. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. Performance for other share classes would differ to the extent they have differences in their fees and expenses. Because Class T shares of the Fund had not commenced operations as of the calendar year ended December 31, 2017, no performance information for Class T shares is provided below. The Fund is the successor to CBRE Clarion Global Infrastructure Value Fund (the “Predecessor Fund”), a mutual fund with substantially similar investment objectives, policies, and restrictions, as a result of the reorganization of the Predecessor Fund into the Fund on July 17, 2017. The Fund’s performance prior to July 17, 2017 reflects the returns achieved by the Predecessor Fund. The Fund's past performance (before and after taxes) is no guarantee of future results.
