You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in A Shares of the Wilmington Funds.

Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys or sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes if 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, the Fund's portfolio turnover rate was 39% of the average value of its portfolio.

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 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 (reflecting any contractual fee waivers). Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Investment Strategy, Heading	rr_StrategyHeading	INVESTMENTS, RISKS AND PERFORMANCE
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	PRINCIPAL INVESTMENT STRATEGIES The Fund invests at least 80% of its assets in a diversified portfolio of U.S. equity (or equity-related) securities of large-cap companies. Large-cap companies are companies that have a market capitalization at the time of purchase at least equal to that of the smallest company in the Russell 1000 Index ($1.62 billion as of May 31, 2011) or at least equal to that of the smallest company expected to be included in the Russell 1000 Index after its next scheduled reconstitution. The Fund expects to invest substantially all of its assets in common stocks of U.S. companies. The Fund's investment adviser determines the tactical allocation of the Fund's assets and uses returns-based and holdings-based style analysis tools to assess the tactical weightings. The Fund's investment adviser currently allocates the Fund's assets between growth and value stocks. Once the investment adviser determines the tactical allocations, the sub-adviser builds a portfolio in accordance with the investment adviser's allocation instructions. The sub-adviser uses quantitative models to construct a portfolio for the Fund. The sub-adviser invests in a representative sample of securities which are included in the Fund's benchmark index (Russell 1000 Index) or another index of large-capitalization companies, weighted to reflect the investment adviser's growth and value tactical allocations. The return for each of the growth and value portions of the portfolio are intended to correlate closely with the return for the corresponding growth and value components of the applicable benchmark. The sub-adviser will use its proprietary quantitative models to rebalance the portfolio and to make buy and sell decisions on individual securities. There is no assurance that the sub-adviser's investment performance will equal or approximate that of the benchmark index.
Risk, Heading	rr_RiskHeading	PRINCIPAL RISKS OF INVESTING IN THE FUND
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. An investment in the Fund is not a deposit of Wilmington Trust Company or any of its affiliates and is not insured or guaranteed by Federal Deposit Insurance Corporation or any other governmental agency. There is no assurance that the Fund will achieve its investment objective. The Fund is subject to the principal risks described below. o ALLOCATION RISK: The risk that the investment adviser will make less than optimal or poor asset allocation decisions. o GROWTH INVESTING RISK: The prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. o LIQUIDITY RISK: The risk that certain securities may be difficult or impossible to sell at the time and the price that the seller would like. o MARKET RISK: The risk that the market value of a security may fluctuate, sometimes rapidly and unpredictably. The prices of equity securities change in response to many factors including the historical and prospective earnings of the issuer, the value of its assets, general economic conditions, interest rates, investor perceptions and market liquidity. o OPPORTUNITY RISK: The risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments. o PORTFOLIO TURNOVER RISK: The risk that high portfolio turnover is likely to lead to increased Fund expenses that may result in lower investment returns. High portfolio turnover is also likely to result in higher short-term capital gains taxable to shareholders. o VALUATION RISK: The risk that the Fund has valued certain of its securities at a higher price than it can sell them. o VALUE INVESTING RISK: The risk that investments in companies whose securities are believed to be undervalued, relative to their underlying profitability, do not appreciate in value as anticipated.
Risk, Lose Money	rr_RiskLoseMoney	You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.
Risk, Not Insured Depository Institution	rr_RiskNotInsuredDepositoryInstitution	An investment in the Fund is not a deposit of Wilmington Trust Company or any of its affiliates and is not insured or guaranteed by Federal Deposit Insurance Corporation or any other governmental agency.
