Expense, Heading	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense, Narrative	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. For Class A shares, you may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Destra mutual funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial professional and in "Shareholder Information" on page 30 of the Fund's Prospectus and "Purchases" on page 28 of the Fund's Statement of Additional Information.

Operating Expenses, Caption	rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover	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 annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal period, the Fund's portfolio turnover rate was 52% of the average value of its portfolio.

Other Expenses, New Fund, Based on Estimates	rr_OtherExpensesNewFundBasedOnEstimates	Class C shares commenced operations on November 1, 2011, and Class P shares have not yet commenced operations. Other Expenses for Class C and Class P shares are based on estimated amounts for the Fund's current fiscal year. Other Expenses may include acquired fund fees, which were not included as fund expenses in the annual report.
Expense Example, Heading	rr_ExpenseExampleHeading	Example
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem all of your shares at the end of those periods. The example also assumes that your investment has 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:

Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	Under normal market conditions, at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes) are invested in equity securities of companies with market capitalizations at the time of investment comparable to companies in the MSCI World Index. The MSCI World Index is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets and consist of twenty-four developed market country indices. At a minimum, the Fund will consist of at least five countries and will have 40% of non-U.S. companies. The Fund may invest in all market capitalizations and its investments generally will include common stocks, preferred stocks, securities convertible into U.S. common stocks, U.S. dollar-denominated American Depositary Receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges. The Fund's sub-adviser, Zebra Capital Management, LLC ("Zebra") seeks to capture a liquidity premium among fundamentally strong, publicly-traded equities. A liquidity premium exists in public equity markets, as more liquid stocks tend to be priced at a premium, while less liquid stocks are priced at a discount, thus having higher expected returns. Zebra targets stocks with strong fundamentals (i.e. earnings, book value, cash flows) that trade less than stocks with comparable fundamentals. Despite producing similar levels of earnings and cash flows, these less liquid stocks can often be purchased at lower prices, offering higher expected returns. Frequently, a fundamentally-sound stock is less traded because it has temporarily fallen out of favor. Over time, Zebra believes the market will recognize this stock again, and its price will increase as its trading activity rises, allowing Zebra to capture its liquidity premium and produce higher returns. Stocks are typically sold when fundamentals deteriorate, trading activity increases relative to changes in a stock's fundamentals, or Zebra believes there are greater opportunities to capture liquidity premium in other stocks. There is no guarantee that the perceived intrinsic value of any investment will be realized.
Risk, Heading	rr_RiskHeading	Principal Risks
Risk, Narrative	rr_RiskNarrativeTextBlock	Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the Fund. Equity Securities Risk - Stock markets are volatile. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. Smaller Company Risk-Market risk is generally greater for lower market capitalization companies because they tend to have more limited product lines, shorter operating histories, less experienced management and more limited financial resources than larger companies. Stocks of smaller companies may be less liquid than those of larger companies and may experience greater price fluctuations. In addition, stocks of smaller companies may not be widely followed by the investment community, resulting in less demand. Foreign Investment Risk-Because the Fund can invest its assets in dollar-denominated foreign instruments, the value of Fund shares can be adversely affected because such securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; lack of liquidity; excessive taxation; government seizure of assets; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Depositary Receipts Risk-Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts. Currency Risk-Even though the non-U.S. securities held by the fund are traded in U.S. dollars, their prices are indirectly influenced by currency fluctuations. Market Risk and Selection Risk - Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will under-perform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money. Value Stocks Risk-Value stocks are subject to the risk that their intrinsic value may never be realized by the market or that their prices may go down. While the Fund's investments in value stocks may limit its downside risk over time, the Fund may produce more modest gains than riskier stock funds as a trade-off for this potentially lower risk. Risks Associated with Active Management-The Fund is an actively managed portfolio and its success depends upon the investment skills and analytical abilities of the Fund's sub-adviser to develop and effectively implement strategies that achieve the Fund's investment objective. Subjective decisions made by the investment sub-adviser may cause the Fund to incur losses or to miss profit opportunities on which it may otherwise have capitalized. General Fund Investing Risks-The Fund is not a complete investment program and you may lose money by investing in the Fund. All investments carry a certain amount of risk and there is no guarantee that the Fund will be able to achieve its investment objective. In general, the Annual Fund Operating Expenses expressed as a percentage of the Fund's average daily net assets will change as Fund assets increase and decrease, and the Fund's Annual Fund Operating Expenses may differ in the future. Purchase and redemption activities by Fund shareholders may impact the management of the Fund and its ability to achieve its objective. Investors in the Fund should have long-term investment perspective and be able to tolerate potentially sharp declines in value. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, entity or person.
