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.

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 31% of the average value of its portfolio.

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 U.S. companies. The Fund will invest in all market capitalizations
and its benchmark will be the Russell 3000® Index. The Russell 3000® Index
measures the performance of the largest 3000 U.S. companies representing
approximately 98% of the investable U.S. equity market and is reconstituted
annually to ensure new and growing equities are reflected. The Fund's
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.

Performance Table, Narrative rr_PerformanceTableNarrativeTextBlock 
The table below shows the variability of the fund's average annual returns by
showing the fund's performance and how they compare over the time periods
indicated with those of a broad measure of market performance. All after-tax
returns are calculated using the historical highest individual federal marginal
income tax rates and do not reflect the impact of state and local taxes.
After-tax returns are shown for Class A shares only; after-tax returns for other
share classes will vary. Actual after-tax returns depend on an investor's tax
situation and may differ from those shown. After-tax returns shown are not
relevant to investors who hold their fund shares through tax-deferred
arrangements, such as 401(k) plans or individual retirement accounts. Class C
and Class P shares have been in existence for less than one calendar year, and
therefore, the table below does not have returns for such share classes.

Performance reflects fee waivers, if any, in effect during the periods
presented. If any such waivers were not in place, returns would be reduced.
