Risk/Return [Heading]	rr_RiskReturnHeading	PNC MARYLAND TAX EXEMPT BOND FUND
Objective [Heading]	rr_ObjectiveHeading	INVESTMENT OBJECTIVE
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Fund seeks to provide a high level of interest income that is exempt from federal and Maryland state and local income taxes.
Expense [Heading]	rr_ExpenseHeading	FUND FEES AND EXPENSES
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The following table describes the fees and expenses that you may pay if you buy and hold Fund shares.
Shareholder Fees Caption [Text]	rr_ShareholderFeesCaption	Shareholder Fees (fees paid directly from your investment)
Operating Expenses Caption [Text]	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 [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 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 21% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	21.00%
Expense Example [Heading]	rr_ExpenseExampleHeading	Example
Expense Example Narrative [Text Block]	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 Class I Shares of 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, except that the Fee Waiver and Expense Reimbursement is reflected only in the one year period below. 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	As a matter of fundamental policy, under normal circumstances, the Fund invests at least 80% of its net assets plus any borrowings for investment purposes in investment-grade municipal bonds and other municipal obligations issued by the State of Maryland, its counties, municipalities and other taxing districts, and other issuers located outside of Maryland that are exempt from federal income taxes, federal alternative minimum tax and Maryland state and local income taxes. A vote of the Fund's shareholders is necessary to change the Fund's fundamental policy. The Fund will invest in securities of varying maturity. Some Fund distributions may be taxable, such as dividends that are derived from taxable investments and distributions of short and long-term capital gains realized on the sale of portfolio securities. Also, Fund dividends will generally be subject to state and local income taxes for any shareholders who are not Maryland residents. In selecting securities for the Fund to buy and sell, PNC Capital Advisors, LLC (the "Adviser") monitors economic trends, including possible changes in interest rates, and evaluates many factors that may influence supply and demand among municipal securities of various structures, maturities and issuers. The Fund will generally purchase investment grade debt municipal obligations, which are those rated in one of the four highest rating categories by at least one nationally recognized statistical rating organization ("NRSRO") or, if unrated, determined by the Adviser to be of comparable quality. The Fund may invest up to 10% of its assets in below-investment grade securities, also known as high yield "junk" bonds (generally rated below the BBB category). The Fund may also invest up to 20% of its assets in interest rate swaps for hedging purposes. The Fund may also invest in derivative securities relating to municipal securities. Derivative instruments include, but are not limited to, options, swaps, futures and options on futures.
Strategy Portfolio Concentration [Text]	rr_StrategyPortfolioConcentration	As a matter of fundamental policy, under normal circumstances, the Fund invests at least 80% of its net assets plus any borrowings for investment purposes in investment-grade municipal bonds and other municipal obligations issued by the State of Maryland, its counties, municipalities and other taxing districts, and other issuers located outside of Maryland that are exempt from federal income taxes, federal alternative minimum tax and Maryland state and local income taxes.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Credit/Counterparty Risk. The values of debt securities or other instruments may be affected by the ability of issuers or the respective counterparties to make principal and interest payments or otherwise meet their obligations to the Fund. If an issuer cannot or will not meet its payment obligations or if its credit rating is lowered or its financial strength deteriorates, the values of its debt securities or other instruments may fall. Obligations issued by U.S. government agencies, authorities, instrumentalities or sponsored enterprises, such as the Government National Mortgage Association, are backed by the full faith and credit of the U.S. Treasury, while obligations issued by others, such as the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation and Federal Home Loan Banks, are backed solely by the ability of the entity to borrow from the U.S. Treasury or by the entity's own resources. Derivatives Risk. Derivatives are financial instruments whose values depend upon, or are derived from, the value of a reference asset, such as one or more underlying assets, indexes or currencies and may include, but are not limited to, options, swaps, futures and options on futures. A small investment in derivatives could have a potentially large impact on the Fund's performance. The use of derivatives involves risks different from the risks associated with investing directly in the reference asset. Derivatives can be volatile, illiquid and difficult to value, and an imperfect correlation may exist between changes in the value of a derivative held by the Fund and the value of the reference asset. Some derivatives are "leveraged" and therefore may magnify or otherwise increase investment losses to the Fund. The Fund's use of derivatives may also increase the amount of taxes payable by shareholders. In addition, there is also the risk that a Fund may be unable to terminate or sell a derivatives position. There is also the risk that derivative counterparties may suffer financial difficulties and may not fulfill their contractual obligations to the Fund. High-Yield Bond Risk. Investments in high-yield, lower rated securities ("junk bonds") involve greater risk than investments in investment grade securities. Such risks include: • A greater risk of price declines than investments in investment grade securities (e.g., securities rated BBB or higher by S&P or Baa or higher by Moody's) due to changes in the issuer's creditworthiness or economic conditions. • The market for high-yield, lower rated securities may be thinner and less active, causing market price volatility and limited liquidity in the secondary market. This may limit the ability of the Fund to sell these securities at their fair market values either to meet redemption requests, or in response to changes in the economy or the financial markets. • A greater risk of default than investments in investment-grade securities due to the predominantly speculative nature of the issuer's ability to make principal and interest payments. Interest Rate Risk. The value of a debt security typically changes in the opposite direction from a change in interest rates. When interest rates go up, the value of a debt security typically goes down. When interest rates go down, the value of a debt security typically goes up. Generally, the longer the maturity or duration of a debt security (or a portfolio of such securities), the more the value of that security (or portfolio of securities) will change as a result of changes in interest rates. Market Risk. Market risk is the risk that securities prices will fall over short or extended periods of time. Historically, the stock markets have moved in cycles, and the value of the Fund's securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may decline in response. Municipal Obligations Risk. An investment in municipal obligations is subject to municipal securities risk. Changes in the local or national economy, and business or political conditions relating to a particular municipal project, municipality, or state in which the Fund invests may make it difficult for the municipality to make interest and principal payments when due and thus could decrease the value of the Fund's investments in municipal bonds. Municipal obligations also may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress, which could have an adverse effect on the market prices of bonds and thus the value of the Fund's investments. The municipal securities held by a Fund may fail to meet certain legal requirements which allow interest distributed from such securities to be tax-exempt, or changes in federal or state tax laws may cause the prices of municipal securities to fall or could affect the tax-exempt status of municipal securities. Municipal securities are also subject to liquidity risk. Non-Diversification Risk. The Fund is non-diversified, which means that the Fund may invest in the securities of relatively few issuers. As a result, the Fund may be more susceptible than a diversified fund to a single adverse economic or political and regulatory occurrence affecting one or more of these issuers, and may experience increased volatility due to its investments in those securities. Prepayment/Extension Risk. Certain debt obligations, such as callable bonds, may be prepaid. Additionally, the loans collateralizing certain mortgage- and asset-backed securities may be prepaid, affecting the value of the mortgage or asset-backed securities to which they relate. The level of interest rates and other factors affect the frequency of such prepayments. In periods of rising interest rates, prepayment rates tend to decrease, which lengthens the average life of callable bonds or mortgage- and asset-backed securities. The market values of securities with longer average lives (longer maturities) tend to be subject to greater interest rate risk and their values are more volatile as a result. In periods of falling interest rates, prepayment rates tend to increase, shortening the average life of a pool of mortgage-backed securities. This leads to the risk that the Fund may lose any potential price appreciation above the bond's call price and have to reinvest the proceeds from prepayments at lower interest rates because prepayments often occur after interest rates have decreased or when interest rates are falling. Single State Risk. The Fund's focus on investments in securities of issuers located in a single state leaves the Fund subject to the particular economic, political and regulatory events relating to such securities to a greater extent than if its assets were not so concentrated. Because the Fund invests primarily in securities issued by Maryland and its municipalities, events in Maryland are likely to affect the Fund's investments and its performance. As a result, the Fund is more vulnerable to unfavorable developments in Maryland than are funds that invest in municipal securities of multiple states. Tax Risk. Distributions of capital gains and other taxable income will be subject to applicable federal, state and local income taxes. Interest on certain municipal securities that are exempt from federal income tax may, nonetheless, be subject to the alternative minimum tax. Shareholders should consult with their tax advisors when determining the taxable nature of any fund distributions for federal, state or local tax purposes. An investment in the Fund may also result in liability for federal alternative minimum tax, both for individual and corporate shareholders. All investments are subject to inherent risks, and an investment in the Fund is no exception. Your investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Accordingly, you may lose money by investing in the Fund.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	PERFORMANCE INFORMATION
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and the performance table below provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund's Class I Shares from year to year and by showing how the average annual returns of the Fund's Class I Shares compare with those of broad measures of market performance. The performance set forth below for the periods prior to February 8, 2010 reflects the performance of corresponding classes of the PNC Maryland Tax-Exempt Bond Fund (the "Predecessor Maryland Tax Exempt Bond Fund"), which was reorganized into the Fund on that date. The Predecessor Maryland Tax Exempt Bond Fund was managed by the Adviser and its predecessors for the periods shown below prior to that date. Prior to September 30, 2002, the quoted performance of Class I Shares reflects the performance of the Institutional Shares, a separate class of shares of the Predecessor Maryland Tax Exempt Bond Fund not offered by this prospectus; adjusted to reflect the expenses of Class I Shares. Class I Shares of the Fund would have substantially similar returns as the Institutional Shares because the shares represent interest in the same portfolio of investments and the annual returns would differ only to the extent that the classes do not have the same expenses. As with all mutual funds, the Fund's past performance (before and after taxes) does not predict the Fund's future performance. Updated information on the Fund's performance can be obtained by visiting http://pncfunds.com/Funds_Performance/Fund_Snapshot/FundID_433/Overview.fs or by calling 1-800-622-FUND (3863).
