Prospectus [Line Items]  
Risk [Text Block] What are the Main (or Principal) Risks of Investing in the Fund?
Tax Exempt Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Tax-Exempt Securities Risk. The amount of public information available about tax-exempt securities is generally less than for corporate equities or bonds. The secondary market for tax-exempt securities also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund’s ability to sell its tax-exempt securities at attractive prices. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the Fund’s investments in tax-exempt securities. Changes in tax policy could adversely affect the tax-exempt status of securities held by the Fund. Tax-exempt issuers can and have defaulted on obligations, been downgraded or commenced insolvency proceedings. Like other issuers and securities, the likelihood that the credit risk associated with such issuers and such securities will increase is greater during times of economic stress and financial instability.
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Interest Rate Risk. Prices of fixed-income securities (including tax-exempt securities) generally fall when interest rates rise. The longer the duration of a fixed-income security, the more susceptible it is to interest rate risk. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.
Issuer Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Issuer Credit Risk. It is possible that interest or principal on securities will not be paid when due. Noninvestment-grade securities generally have a higher default risk than investment-grade securities. Such non-payment or default may reduce the value of the Fund’s portfolio holdings, its share price and its performance.
Counterparty Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose money or to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Liquidity Risk. Certain securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. These features may make it more difficult to sell or buy a security at a favorable price or time. Noninvestment-grade securities generally have less liquidity than investment-grade securities. Liquidity risk also refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract when it wants to. Over-the-counter derivative contracts generally carry greater liquidity risk than exchange-traded contracts.
Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Tax Risk. In order to be tax-exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable. Income from tax-exempt securities held by the Fund could also become taxable because of changes in tax laws or interpretations by taxing authorities, resulting in a higher tax liability for shareholders and potentially impacting Fund performance. The federal income tax treatment of payments in respect of certain derivative contracts is unclear. The Fund also may invest in money market funds, market discount bonds, enter into credit default swap arrangements and other derivative transactions, and engage in other permissible activities that will likely cause the Fund to realize a limited amount of ordinary income or short-term capital gains (which are treated as ordinary income for federal income tax purposes). Consequently, for each of these reasons, the Fund may receive payments, and make distributions, that are treated as ordinary income for federal income tax purposes. Income from the Fund also may be subject to AMT.
Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Leverage Risk. Leverage risk is created when an investment, which includes, for example, a derivative contract, exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain. Investments can have these same results if their returns are based on a multiple of a specified index, security or other benchmark.
Call Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Call Risk. The Fund’s performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below or above its current market value.
Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Sector Risk. A substantial part of the Fund’s portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses, or with other similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these issuers or entities.
Prepayment and Extension Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Prepayment and Extension Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of municipal mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities. When interest rates rise, homeowners are less likely to prepay their mortgages. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security, and the price of mortgage-backed securities may decrease more than the price of other fixed-income securities when interest rates rise.
Credit Enhancement Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund.
Risk Related to the Economy [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Global economic, political and financial conditions including geopolitical conflicts, legislative changes, industry or economic trends and developments or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, have a significant effect on financial markets generally and cause the Fund to experience volatility, illiquidity, shareholder redemptions and/or other potentially adverse effects. Among other investments, lower-grade bonds may be particularly sensitive to changes in the economy.
Risk of Investing in Derivative Contracts and Hybrid Instruments [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Risk of Investing in Derivative Contracts and Hybrid Instruments. Derivative contracts and hybrid instruments involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts and instruments include valuation and tax issues, increased potential for losses and/or costs to the Fund, and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts and hybrid instruments may also involve other risks described in this Prospectus, such as interest rate, credit, liquidity and leverage risks.
Risk Associated with Noninvestment Grade Securities [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Risk Associated with Noninvestment-Grade Securities. Securities rated below investment grade may be subject to greater interest rate, credit and liquidity risks than investment-grade securities. These securities are considered speculative with respect to the issuer’s ability to pay interest and repay principal.
Technology Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ■ Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective(s) and strategy described in this Prospectus. For example, proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.
