Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. 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 Nuveen Mutual Funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial advisor and in “What Share Classes We Offer” on page 42 of the Fund’s prospectus, “How to Reduce Your Sales Charge” on page 45 of the prospectus and “Purchase and Redemption of Fund Shares” on page S-79 of the Fund’s statement of additional information.

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 9% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following 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 your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are at the lesser of Total Annual Fund Operating Expenses or the applicable expense limitation. 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	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. Under normal market conditions, the Fund generally invests in intermediate- and long-term bonds with a duration of between two and ten years, and generally maintains a weighted average portfolio duration of between four and seven years. Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as “high yield” or “junk” bonds. The Fund seeks to protect investors from inflation in two ways. First, as with other municipal bond funds, a portion of the Fund’s current yield compensates an investor for current inflation expectations. Second, the Fund seeks to mitigate the effect that subsequent increases in inflation expectations may have on the purchasing power of the Fund by investing in inflation-linked instruments, such as Consumer Price Index (CPI) swaps, in amounts sufficient to approximate the duration characteristics of the Fund’s underlying municipal bond portfolio. The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. The Fund’s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include: Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax. Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted. Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Declining Inflation Risk—The Fund’s inflation-hedging strategy primarily involves the use of CPI swaps. The Fund will benefit from a CPI swap if actual inflation during the swap’s period is greater than the level of inflation expected for that period at the time the swap was initiated. However, if actual inflation turns out to be less than expected, the Fund will lose money on the swap. In such circumstances, the Fund will underperform an otherwise identical municipal bond fund that had not utilized such inflation hedges. High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities. Income Risk—The Fund’s income could decline during periods of falling interest rates. Inflation-Linked Instruments Risk—The returns of CPI swaps or other inflation-linked instruments reflect a specified index of inflation. There can be no assurance that the inflation index used will accurately measure either the actual future rate of inflation or the rate of expected future inflation reflected in the prices and yields of municipal bonds. As a result, the Fund’s inflation-hedging strategy may not perform as expected. CPI swaps may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. CPI swaps create leverage, which may cause the Fund’s net asset value and returns to be more volatile than they would be if the Fund had not used swaps. CPI swaps also expose the Fund to counterparty risk, which is the risk that the swap counterparty will not fulfill its contractual obligations. Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably. Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body. Non-Diversification Risk—As a non-diversified fund, the Fund may invest a larger portion of its assets in the securities of a limited number of issuers and may be more sensitive to any single economic, business, political or regulatory occurrence than a diversified fund. Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	Non-Diversification Risk—As a non-diversified fund, the Fund may invest a larger portion of its assets in the securities of a limited number of issuers and may be more sensitive to any single economic, business, political or regulatory occurrence than a diversified fund.

After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Portfolio Turnover

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 9% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. Under normal market conditions, the Fund generally invests in intermediate- and long-term bonds with a duration of between two and ten years, and generally maintains a weighted average portfolio duration of between four and seven years.

Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as “high yield” or “junk” bonds.

The Fund seeks to protect investors from inflation in two ways. First, as with other municipal bond funds, a portion of the Fund’s current yield compensates an investor for current inflation expectations. Second, the Fund seeks to mitigate the effect that subsequent increases in inflation expectations may have on the purchasing power of the Fund by investing in inflation-linked instruments, such as Consumer Price Index (CPI) swaps, in amounts sufficient to approximate the duration characteristics of the Fund’s underlying municipal bond portfolio.

The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature.

The Fund’s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.

Principal Risks

The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include:

Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations.

Declining Inflation Risk—The Fund’s inflation-hedging strategy primarily involves the use of CPI swaps. The Fund will benefit from a CPI swap if actual inflation during the swap’s period is greater than the level of inflation expected for that period at the time the swap was initiated. However, if actual inflation turns out to be less than expected, the Fund will lose money on the swap. In such circumstances, the Fund will underperform an otherwise identical municipal bond fund that had not utilized such inflation hedges.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund’s income could decline during periods of falling interest rates.

Inflation-Linked Instruments Risk—The returns of CPI swaps or other inflation-linked instruments reflect a specified index of inflation. There can be no assurance that the inflation index used will accurately measure either the actual future rate of inflation or the rate of expected future inflation reflected in the prices and yields of municipal bonds. As a result, the Fund’s inflation-hedging strategy may not perform as expected. CPI swaps may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions and could result in losses that significantly exceed the Fund’s original investment. CPI swaps create leverage, which may cause the Fund’s net asset value and returns to be more volatile than they would be if the Fund had not used swaps. CPI swaps also expose the Fund to counterparty risk, which is the risk that the swap counterparty will not fulfill its contractual obligations.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities.

Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably.

Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body.

Non-Diversification Risk—As a non-diversified fund, the Fund may invest a larger portion of its assets in the securities of a limited number of issuers and may be more sensitive to any single economic, business, political or regulatory occurrence than a diversified fund.

Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers.

Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer.

Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the Fund’s performance for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the one-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 4.02% and 1.11%, respectively, for the quarters ended March 31, 2012 and June 30, 2012.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. 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. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Portfolio Turnover

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 15% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. Under normal market conditions, the Fund maintains a weighted average portfolio duration of between 3 and 10 years, and expects to generally maintain a weighted average portfolio duration of between 4.5 and 7 years.

Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as “high yield” or “junk” bonds.

The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature.

The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished.

The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, and to manage the effective maturity or duration of securities in the Fund’s portfolio.

The Fund’s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.

Principal Risks

The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include:

Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk.

Derivatives Risk—The use of futures contracts, options on futures contracts, swap agreements, including interest rate swaps, and options on swap agreements involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund’s investment in inverse floaters because of the leveraged nature of these investments.

Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment.

Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably.

Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body.

Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers.

Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer.

Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Portfolio Turnover

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 12% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund generally invests in bonds with short-to intermediate-term maturities. The Fund will attempt to maintain the weighted average maturity of its portfolio securities at three to seven years under normal market conditions.

Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as “high yield” or “junk” bonds.

The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature.

The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished.

The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, and to manage the effective maturity or duration of securities in the Fund’s portfolio.

The Fund’s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.

Principal Risks

The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include:

Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk.

Derivatives Risk—The use of futures contracts, options on futures contracts, swap agreements, including interest rate swaps, and options on swap agreements involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund’s investment in inverse floaters because of the leveraged nature of these investments.

Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment.

Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably.

Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body.

Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers.

Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer.

Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the ten-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 3.81% and -1.76%, respectively, for the quarters ended September 30, 2009 and June 30, 2004.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. 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. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Example

The following 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 your shares at the end of a period. 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:

Redemption

Expense Example Nuveen High Yield Municipal Bond Fund (USD $)	A	B	C	I
1 Year	503	563	143	66
3 Years	680	805	443	208
5 Years	872	971	766	362
10 Years	1,425	1,699	1,680	810

No Redemption

Expense Example, No Redemption Nuveen High Yield Municipal Bond Fund (USD $)	A	B	C	I

5 Years	872	871	766	362
10 Years	1,425	1,699	1,680	810

Portfolio Turnover

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 13% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund is a long-term bond fund and, as such, will generally maintain, under normal market conditions, an investment portfolio with an overall weighted average maturity of greater than 10 years.

The Fund invests significantly in lower-quality long-term municipal bonds and may employ effective leverage through investments in inverse floaters. These investment strategies should be considered high risk relative to strategies employed by investment grade municipal bond funds.

Under normal market conditions, the Fund invests at least 65% of its net assets in low-to-medium-quality bonds rated BBB/Baa or lower at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. Below investment grade municipal bonds (those rated BB/Ba or lower) are commonly referred to as “high yield” or “junk” bonds. The Fund may invest up to 10% of its net assets in defaulted municipal bonds (i.e., bonds on which the issuer has not paid principal or interest on time).

The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature.

The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. The Fund may invest in inverse floaters that create effective leverage of up to 30% of the Fund’s total investment exposure.

The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, and to manage the effective maturity or duration of securities in the Fund’s portfolio.

The Fund’s sub-adviser uses a research-intensive investment process to identify high-yielding municipal bonds that offer attractive value in terms of their current yields, prices, credit quality, liquidity and future prospects. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.

Principal Risks

The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include:

Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Because the Fund invests at least 65% of its assets in low-to-medium-quality bonds, including high yield securities, the Fund’s credit risks are greater than those of funds that buy only investment grade securities. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk.

Defaulted Bond Risk—Defaulted bonds are speculative and involve substantial risks in addition to the risks of investing in high yield securities that have not defaulted. The Fund generally will not receive interest payments on the defaulted bonds and there is a substantial risk that principal will not be repaid. In any reorganization or liquidation proceeding relating to a defaulted bond, the Fund may lose its entire investment.

Derivatives Risk—The use of futures contracts, options on futures contracts, swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund’s investment in inverse floaters because of the leveraged nature of these investments.

Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment.

Liquidity Risk—The secondary market for municipal bonds, and particularly for high-yield municipal bonds, tends to be less well developed and less liquid than many other securities markets. As a result, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices. The Fund may invest a significant portion of its assets in unrated bonds. The market for these bonds may be less liquid than the market for rated bonds of comparable quality.

Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably.

Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body.

Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers.

Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer.

Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

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 17% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following 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 your shares at the end of a period. 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:

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund is a long-term bond fund and, as such, will generally maintain, under normal market conditions, an investment portfolio with an overall weighted average maturity of greater than 10 years. Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as “high yield” or “junk” bonds. The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, and to manage the effective maturity or duration of securities in the Fund’s portfolio. The Fund’s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include: Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax. Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted. Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk. Derivatives Risk—The use of futures contracts, options on futures contracts, swap agreements, including interest rate swaps, and options on swap agreements involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments. High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities. Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise. Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund’s investment in inverse floaters because of the leveraged nature of these investments. Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment. Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably. Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body. Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

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 13% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund is a long-term bond fund and, as such, will generally maintain, under normal market conditions, an investment portfolio with an overall weighted average maturity of greater than 10 years. The Fund invests significantly in lower-quality long-term municipal bonds and may employ effective leverage through investments in inverse floaters. These investment strategies should be considered high risk relative to strategies employed by investment grade municipal bond funds. Under normal market conditions, the Fund invests at least 65% of its net assets in low-to-medium-quality bonds rated BBB/Baa or lower at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. Below investment grade municipal bonds (those rated BB/Ba or lower) are commonly referred to as “high yield” or “junk” bonds. The Fund may invest up to 10% of its net assets in defaulted municipal bonds (i.e., bonds on which the issuer has not paid principal or interest on time). The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. The Fund may invest in inverse floaters that create effective leverage of up to 30% of the Fund’s total investment exposure. The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, and to manage the effective maturity or duration of securities in the Fund’s portfolio. The Fund’s sub-adviser uses a research-intensive investment process to identify high-yielding municipal bonds that offer attractive value in terms of their current yields, prices, credit quality, liquidity and future prospects. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include: Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax. Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted. Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Because the Fund invests at least 65% of its assets in low-to-medium-quality bonds, including high yield securities, the Fund’s credit risks are greater than those of funds that buy only investment grade securities. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk. Defaulted Bond Risk—Defaulted bonds are speculative and involve substantial risks in addition to the risks of investing in high yield securities that have not defaulted. The Fund generally will not receive interest payments on the defaulted bonds and there is a substantial risk that principal will not be repaid. In any reorganization or liquidation proceeding relating to a defaulted bond, the Fund may lose its entire investment. Derivatives Risk—The use of futures contracts, options on futures contracts, swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments. High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities. Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise. Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund’s investment in inverse floaters because of the leveraged nature of these investments. Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment. Liquidity Risk—The secondary market for municipal bonds, and particularly for high-yield municipal bonds, tends to be less well developed and less liquid than many other securities markets. As a result, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices. The Fund may invest a significant portion of its assets in unrated bonds. The market for these bonds may be less liquid than the market for rated bonds of comparable quality. Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably. Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body. Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Nuveen All-American Municipal Bond Fund

Nuveen All-American Municipal Bond Fund

Investment Objective

The investment objective of the Fund is to provide you with as high a level of current interest income exempt from regular federal income taxes as is consistent with preservation of capital.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Example

The following 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 your shares at the end of a period. 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:

5 Years	804	803	697	291
10 Years	1,277	1,554	1,534	653

Portfolio Turnover

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 17% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund is a long-term bond fund and, as such, will generally maintain, under normal market conditions, an investment portfolio with an overall weighted average maturity of greater than 10 years.

Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as “high yield” or “junk” bonds.

The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature.

The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished.

The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, and to manage the effective maturity or duration of securities in the Fund’s portfolio.

The Fund’s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.

Principal Risks

The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include:

Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk.

Derivatives Risk—The use of futures contracts, options on futures contracts, swap agreements, including interest rate swaps, and options on swap agreements involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund’s investment in inverse floaters because of the leveraged nature of these investments.

Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment.

Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably.

Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body.

Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers.

Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer.

Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the ten-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 11.69% and -8.04%, respectively, for the quarters ended September 30, 2009 and December 31, 2008.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. 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. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Portfolio Turnover

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. For the fiscal period February 1, 2013 (commencement of operations) through April 30, 2013, the Fund’s portfolio turnover rate was 0%* of the average value of its portfolio.

*   Rounds to less than 1%.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. Under normal market conditions, the Fund will maintain an investment portfolio with a weighted average effective duration of less than 4.5 years.

The Fund invests significantly in lower-quality municipal bonds and may employ effective leverage through investments in inverse floaters. These investment strategies should be considered high risk relative to strategies employed by investment grade municipal bond funds.

The Fund generally invests at least 65% of its net assets in low-to-medium-quality bonds rated BBB/Baa or lower at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality, although it may invest less than this amount during abnormal market conditions or periods of large cash inflows or outflows. Below investment grade municipal bonds (those rated BB/Ba or lower) are commonly referred to as “high yield” or “junk” bonds. The Fund may invest up to 10% of its net assets in defaulted municipal bonds (i.e., bonds on which the issuer has not paid principal or interest on time).

The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature.

The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. The Fund may invest in inverse floaters that create effective leverage of up to 15% of the Fund’s total investment exposure. The Fund will only invest in inverse floating rate securities whose underlying bonds are rated A or higher.

The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund’s portfolio or for speculative purposes in an effort to increase the Fund’s yield or to enhance returns. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions.

The Fund’s sub-adviser uses a research-intensive investment process to identify high-yielding municipal bonds that offer attractive value in terms of their current yields, prices, credit quality, liquidity and future prospects. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.

Principal Risks

The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include:

Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Because the Fund invests at least 65% of its assets in low-to-medium-quality bonds, including high yield securities, the Fund’s credit risks are greater than those of funds that buy only investment grade securities. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk.

Defaulted Bond Risk—Defaulted bonds are speculative and involve substantial risks in addition to the risks of investing in high yield securities that have not defaulted. The Fund generally will not receive interest payments on the defaulted bonds and there is a substantial risk that principal will not be repaid. In any reorganization or liquidation proceeding relating to a defaulted bond, the Fund may lose its entire investment.

Derivatives Risk—The use of futures contracts, options on futures contracts, swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund’s investment in inverse floaters because of the leveraged nature of these investments.

Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment.

Liquidity Risk—The secondary market for municipal bonds, and particularly for high-yield municipal bonds, tends to be less well developed and less liquid than many other securities markets. As a result, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices. The Fund may invest a significant portion of its assets in unrated bonds. The market for these bonds may be less liquid than the market for rated bonds of comparable quality.

Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably.

Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body.

Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers.

Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer.

Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

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. For the fiscal period February 1, 2013 (commencement of operations) through April 30, 2013, the Fund’s portfolio turnover rate was 0%* of the average value of its portfolio. *   Rounds to less than 1%.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. Under normal market conditions, the Fund will maintain an investment portfolio with a weighted average effective duration of less than 4.5 years. The Fund invests significantly in lower-quality municipal bonds and may employ effective leverage through investments in inverse floaters. These investment strategies should be considered high risk relative to strategies employed by investment grade municipal bond funds. The Fund generally invests at least 65% of its net assets in low-to-medium-quality bonds rated BBB/Baa or lower at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality, although it may invest less than this amount during abnormal market conditions or periods of large cash inflows or outflows. Below investment grade municipal bonds (those rated BB/Ba or lower) are commonly referred to as “high yield” or “junk” bonds. The Fund may invest up to 10% of its net assets in defaulted municipal bonds (i.e., bonds on which the issuer has not paid principal or interest on time). The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. The Fund may invest in inverse floaters that create effective leverage of up to 15% of the Fund’s total investment exposure. The Fund will only invest in inverse floating rate securities whose underlying bonds are rated A or higher. The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund’s portfolio or for speculative purposes in an effort to increase the Fund’s yield or to enhance returns. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions. The Fund’s sub-adviser uses a research-intensive investment process to identify high-yielding municipal bonds that offer attractive value in terms of their current yields, prices, credit quality, liquidity and future prospects. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The price and yield of this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include: Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax. Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted. Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Because the Fund invests at least 65% of its assets in low-to-medium-quality bonds, including high yield securities, the Fund’s credit risks are greater than those of funds that buy only investment grade securities. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk. Defaulted Bond Risk—Defaulted bonds are speculative and involve substantial risks in addition to the risks of investing in high yield securities that have not defaulted. The Fund generally will not receive interest payments on the defaulted bonds and there is a substantial risk that principal will not be repaid. In any reorganization or liquidation proceeding relating to a defaulted bond, the Fund may lose its entire investment. Derivatives Risk—The use of futures contracts, options on futures contracts, swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments. High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities. Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise. Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Interest rate risk may be increased by the Fund’s investment in inverse floaters because of the leveraged nature of these investments. Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment. Liquidity Risk—The secondary market for municipal bonds, and particularly for high-yield municipal bonds, tends to be less well developed and less liquid than many other securities markets. As a result, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices. The Fund may invest a significant portion of its assets in unrated bonds. The market for these bonds may be less liquid than the market for rated bonds of comparable quality. Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably. Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body. Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. The Fund generally invests in bonds with short-to intermediate-term maturities. The Fund will attempt to maintain the weighted average maturity of its portfolio securities at three to seven years under normal market conditions. Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as “high yield” or “junk” bonds. The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, and to manage the effective maturity or duration of securities in the Fund’s portfolio. The Fund’s sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued municipal bonds that offer above-average total return. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.

Bar Chart Narrative [Text Block]	rr_BarChartNarrativeTextBlock	The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.
Bar Chart Does Not Reflect Sales Loads [Text]	rr_BarChartDoesNotReflectSalesLoads	The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.
Bar Chart Closing [Text Block]	rr_BarChartClosingTextBlock	During the ten-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 3.81% and -1.76%, respectively, for the quarters ended September 30, 2009 and June 30, 2004.
Performance Table Heading	rr_PerformanceTableHeading	Average Annual Total Returns for the Periods Ended December 31, 2012
Performance Table Uses Highest Federal Rate	rr_PerformanceTableUsesHighestFederalRate	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.
Performance Table One Class of after Tax Shown [Text]	rr_PerformanceTableOneClassOfAfterTaxShown	After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary.
Performance Table Narrative	rr_PerformanceTableNarrativeTextBlock	The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. 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. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.
