Prospectus [Line Items]  
Risk [Text Block]

Asset Allocation Risk. The Fund is subject to asset allocation risk, which is the risk that the selection of the underlying funds and the allocation of the Fund’s assets among the various asset classes and market segments will cause the Fund to underperform other funds with a similar investment objective.

Madison Conservative Allocation Fund | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. The Fund, through the underlying funds, is subject to interest rate risk, which is the risk that the value of your investment will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the market value of income-bearing securities. When interest rates rise, bond prices fall; generally, the longer a bond’s maturity, the more sensitive it is to this risk.

Madison Conservative Allocation Fund | Credit and Prepayment/Extension Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Credit and Prepayment/Extension Risk. The Fund, through the underlying funds, is also subject to credit risk, which is the risk that issuers of debt securities may be unable to meet their interest or principal payment obligations when due. There is also prepayment/extension risk, which is the chance that a rise/fall in interest rates will reduce/extend the life of a mortgage-backed security by increasing/decreasing mortgage prepayments, typically reducing the underlying fund’s return.

Madison Conservative Allocation Fund | Non-Investment Grade Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Non-Investment Grade Security Risk. The Fund, through the underlying funds, may invest in non-investment grade securities (i.e., “junk” bonds). Issuers of non-investment grade securities are typically in weak financial health and their ability to pay interest and principal is uncertain. Compared to issuers of investment-grade bonds, they are more likely to encounter financial difficulties and to be materially affected by these difficulties when they do encounter them. “Junk” bond markets may react strongly to adverse news about an issuer or the economy, or to the perception or expectation of adverse news.

Madison Conservative Allocation Fund | Equity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Equity Risk. The Fund, through the underlying funds, is subject to equity risk. Equity risk is the risk that securities held by the Fund will fluctuate in value due to general market or economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, and the circumstances and performance of companies whose securities the Fund holds. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Madison Conservative Allocation Fund | ETF Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

ETF Risks. The main risks of investing in ETFs are the same as investing in a portfolio of equity securities comprising the index on which the ETF is based, although lack of liquidity in an ETF could result in it being more volatile than the securities comprising the index. Additionally, the market prices of ETFs will fluctuate in accordance with both changes in the market value of their underlying portfolio securities and due to supply and demand for the instruments on the exchanges on which they are traded (which may result in their trading at a discount or premium to their net asset values). Index-based ETF investments may not replicate exactly the performance of their specific index because of transaction costs and because of the temporary unavailability of certain component securities of the index.

Madison Conservative Allocation Fund | Foreign Security Risk [Member]

Foreign Security Risk. Investments of underlying funds that invest in foreign securities involve risks relating to currency fluctuations and to political, social and economic developments abroad, as well as risks resulting from differences between the regulations to which U.S. and foreign issuers and markets are subject. These risks may be greater in emerging markets. The investment markets of emerging countries are generally more volatile than markets of developed countries with more mature economies.

Madison Conservative Allocation Fund | Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. While the majority of the Fund’s assets will typically be invested in underlying funds that invest primarily in debt securities, to the extent that the Fund invests in underlying funds that invest in equities, the Fund is subject to market risk, which is the risk that the value of an investment may fluctuate in response to stock market movements.

Madison Diversified Income Fund | Non-Investment Grade Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Non-Investment Grade Security Risk. Issuers of non-investment grade securities (i.e., “junk” bonds) are typically in weak financial health and, compared to issuers of investment-grade bonds, they are more likely to encounter financial difficulties and to be materially affected by these difficulties when they do encounter them. Because the Fund may invest a significant portion of its assets in these securities, the Fund may be subject to greater levels of credit and liquidity risk than a fund that does not invest in such securities. These securities are considered predominately speculative with respect to the issuer's continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce the Fund's ability to sell these securities. If the issuer of a security is in default with respect to interest or principal payments, the Fund may lose its entire investment. Because of the risks involved in investing in non-investment grade securities, an investment in a fund that invests in such securities should be considered speculative.

Madison Diversified Income Fund | Equity Risk [Member]

Equity Risk. The Fund is subject to equity risk. Equity risk is the risk that securities held by the Fund will fluctuate in value due to general market or economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, and the circumstances and performance of companies whose securities the fund holds. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Market Risk. The share price of the Fund reflects the value of the securities it holds. If a security’s price falls, the share price of the Fund will go down (unless another security’s price rises by an offsetting amount). If the Fund’s share price falls below the price you paid for your shares, you could lose money when you redeem your shares.

Madison Diversified Income Fund | Capital Gain Realization Risks to Taxpaying Shareholders [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Capital Gain Realization Risks to Taxpaying Shareholders. Because of the focused nature of the Fund’s equity portfolio, the Fund is susceptible to capital gain realization. In other words, when the Fund is successful in achieving its investment objective, portfolio turnover may generate more capital gains per share than funds that hold greater numbers of individual securities. The Fund’s sale of just a few positions will represent a larger percentage of the Fund’s assets compared with, say, a fund that has hundreds of securities positions.

Madison Diversified Income Fund | Real Estate Investment Trusts "REITs" Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Real Estate Investment Trusts "REITs" Risk. REITs pool investors’ funds for investment primarily in real estate properties or real estate-related loans.  REITs generally derive their income from rents on the underlying properties or interest on the underlying loans, and their value is impacted by changes in the value of the underlying property or changes in interest rates affecting the underlying loans owned by the REITs.  REITs are more susceptible to risks associated with the ownership of real estate and the real estate industry in general.  These risks can include, but are not limited, fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local economic conditions; decreases in market rates for rents; increases in competition, property taxes, capital expenditures or operating expenses; and other economic, political or regulatory occurrences affecting the real estate industry.  In addition, REITs depend upon specialized management skills, may not be diversified (which may increase the price volatility of REITs), may have less trading volume and liquidity, and may be subject to more abrupt or erratic price movements than the overall securities market.  REITs are not taxed on income distributed to shareholders provided they comply with several requirements of the Internal Revenue Code of 1986, as amended.  REITs are subject to the risk of failing to qualify for favorable tax treatment under the Code.

Foreign Security and Emerging Market Risk. Investments in foreign securities, including investments in ADRs (defined below) and emerging market securities, involve risks relating to currency fluctuations and to political, social, and economic developments abroad, as well as risks resulting from differences between the regulations to which U.S. and foreign issuers and markets are subject. These risks may be greater in emerging markets. The investment markets of emerging countries are generally more volatile than markets of developed countries with more mature economies.

Madison Diversified Income Fund | Depository Receipt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Depository Receipt Risk. Depository receipts, such as American depository receipts (“ADRs”), global depository receipts (“GDRs”), and European depository receipts (“EDRs”), may be issued in sponsored or un-sponsored programs.  In a sponsored program, a security issuer has made arrangements to have its securities traded in the form of depository receipts.  In an un-sponsored program, the issuer may not be directly involved in the creation of the program.  Depository receipts involve many of the same risks as direct investments in foreign securities.  These risks include, but are not limited to, fluctuations in currency exchange rates, which are affected by international balances of payments and other financial conditions; government interventions; and speculation.  With respect to certain foreign countries, there is the possibility of expropriation or nationalization of assets, confiscatory taxation, political and social upheaval, and economic instability.  Investments in depository receipts that are traded over the counter may also be subject to liquidity risk.

Madison Tax-Free National Fund | Risks of General Obligation versus Limited Purpose Bonds  
Prospectus [Line Items]  
Risk [Text Block]

Risks of General Obligation versus Limited Purpose Bonds. General obligation bonds are backed by the unlimited taxing powers of the municipality issuing the bonds. Limited purpose bonds or “limited tax general obligation bonds” are more risky because the pledged tax revenues backing the bonds are limited to revenue sources and maximum property tax millage amounts. For example, a bond issued by the Commonwealth of Virginia has an unlimited tax pledge backing the debt service, while a bond issued for Arlington, Virginia Public School system has a limited revenue source which is property taxes in the district.

Madison Tax-Free National Fund | Legislative Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Legislative Risk. Municipal bonds pay lower rates of interest than comparable corporate bonds because of the tax-free nature of their interest payments. If the tax-free status of municipal securities is altered or eliminated by an act of Congress or the legislature of any particular state, the value of the affected bonds will drop. This is because their low interest payments will be less competitive with other taxable bonds.

Madison Tax-Free National Fund | Call Risk  
Prospectus [Line Items]  
Risk [Text Block]

Call Risk. If a bond issuer “calls” a bond held by the Fund (i.e., pays it off at a specified price before it matures), the Fund could have to reinvest the proceeds at a lower interest rate. It may also experience a loss if the bond is called at a price lower than what the Fund paid for the bond.

Madison Tax-Free National Fund | Risk of Default [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Risk of Default. Although Madison monitors the condition of bond issuers, it is still possible that unexpected events could cause the issuer to be unable to pay either principal or interest on its bond. This could cause the bond to go into default and lose value. Some federal agency securities are not backed by the full faith and credit of the United States, so in the event of default, the Fund would have to look to the agency issuing the bond for ultimate repayment.

Madison Tax-Free National Fund | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. The Fund is also subject to liquidity risk, which means there may be little or no trading activity for the debt securities in which the Fund invests, and that may make it difficult for the Fund to value accurately and/or sell those securities. In addition, liquid debt securities in which the Fund invests are subject to the risk that during certain periods their liquidity will shrink or disappear suddenly and without warning as a result of adverse economic, regulatory or market conditions, or adverse investor perceptions. If the Fund experiences rapid, large redemptions during a period in which a substantial portion of its debt securities are illiquid, the Fund may be forced to sell those securities at a discount, which could result in significant Fund and shareholder losses. Liquidity risk may be higher for this Fund than those of income funds that hold U.S. government securities as part of their portfolios because the liquidity of U.S. government securities has historically continued in times of recent market stress.  This Fund normally holds few or no U.S. government securities.

Madison Tax-Free National Fund | Capital Gains Tax-Related Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Capital Gains Tax-Related Risk. While dividend income is expected to be tax-free, Fund shareholders can recognize taxable income in two ways: (1) if you sell your shares at a price that is higher than when you bought them, you will have a taxable capital gain; on the other hand, if you sell your shares at a price that is lower than the price when you bought them, you will have a capital loss; and (2) in the event the Fund sells more securities at prices higher than when they were bought by the Fund, the Fund may pass through the profit it makes from these transactions by making a taxable capital gain distribution.

Madison Tax-Free National Fund | Alternative Minimum Tax (AMT) Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Alternative Minimum Tax (AMT) Risk. In addition to possible taxable capital gain distributions, certain bonds owned by the Fund generate income that is subject to the federal AMT. The interest on these “private activity” bonds could become subject to AMT if you are a taxpayer that meets the AMT criteria. If you are subject to AMT, you will be required to add any income attributable to these bonds (as reported by the Fund annually) to other so-called “tax preference items” to determine possible liability for AMT. Income from AMT bonds may not exceed 20% of the Fund’s net income.

Credit Risk and Prepayment/Extension Risk. The Fund is subject to credit risk, which is the risk that issuers of debt securities may be unable to meet their interest or principal payment obligations when due. There is also prepayment/extension risk, which is the chance that a fall/rise in interest rates will reduce/extend the life of a mortgage-backed security by increasing/decreasing mortgage prepayments, typically reducing the Fund’s return.

Madison Core Bond Fund | Non-Investment Grade Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Non-Investment Grade Security Risk. To the extent that the Fund invests in non-investment grade securities, the Fund is also subject to above-average credit, market and other risks. Issuers of non-investment grade securities (i.e., “junk” bonds) are typically in weak financial health and their ability to pay interest and principal is uncertain. Compared to issuers of investment grade bonds, they are more likely to encounter financial difficulties and to be materially affected by these difficulties when they do encounter them. “Junk” bond markets may react strongly to adverse news about an issuer or the economy, or to the perception or expectation of adverse news.

The Fund is also subject to liquidity risk, which means there may be little or no trading activity for the debt securities in which the Fund invests, and that may make it difficult for the Fund to value accurately and/or sell those securities. In addition, liquid debt securities in which the Fund invests are subject to the risk that during certain periods their liquidity will shrink or disappear suddenly and without warning as a result of adverse economic, regulatory or market conditions, or adverse investor perceptions. If the Fund experiences rapid, large redemptions during a period in which a substantial portion of its debt securities are illiquid, the Fund may be forced to sell those securities at a discount, which could result in significant Fund and shareholder losses.

Risk [Text Block]

Mortgage-Backed Securities Risk. The Fund may own obligations backed by mortgages issued by a government agency or through a government-sponsored program. If the mortgage holders prepay principal during a period of falling interest rates, the Fund could be exposed to prepayment risk. In that case, the Fund would have to reinvest the proceeds at a lower interest rate. The security itself may not increase in value with the corresponding drop in rates since the prepayment acts to shorten the maturity of the security.

Equity Risk. The Fund is subject to equity risk. Equity risk is the risk that securities held by the Fund will fluctuate in value due to general market or economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, and the circumstances and performance of companies whose securities the Fund holds. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Market Risk. The share price of the Fund reflects the value of the securities it holds. If a security’s price falls, the share price of the Fund will go down (unless another security’s price rises by an offsetting amount). If the Fund’s share price falls below the price you paid for your shares, you could lose money when you redeem your shares.

Madison Covered Call & Equity Income Fund | Option Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Option Risk. There are several risks associated with transactions in options on securities, as follows:

 

•There are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing a given transaction not to achieve its objectives.

 

•As the writer of a covered call option, the Fund forgoes, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but has retained the risk of loss should the price of the underlying security decline.

 

•The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it may not be able to effect a closing purchase transaction in order to terminate its obligation under the option and must then deliver the underlying security at the exercise price.

 

•There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position. If the Fund were unable to close out a covered call option that it had written on a security, it would not be able to sell the underlying security unless the option expired without exercise.

 

 

•The hours of trading for options may not conform to the hours during which the underlying securities are traded. To the extent that the options markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that cannot be reflected in the options markets.

 

•The value of call options will be affected by changes in the value and dividend rates of the underlying common stocks, an increase in interest rates, changes in the actual or perceived volatility of the stock market and the underlying common stocks and the remaining time to the options’ expiration. Additionally, the exercise price of an option may be adjusted downward before the option’s expiration as a result of the occurrence of events affecting the underlying equity security. A reduction in the exercise price of an option would reduce the Fund’s capital appreciation potential on the underlying security.

 

•When the Fund writes covered put options, it bears the risk of loss if the value of the underlying stock declines below the exercise price. If the option is exercised, the Fund could incur a loss if it is required to purchase the stock underlying the put option at a price greater than the market price of the stock at the time of exercise. Also, while the Fund’s potential gain in writing a covered put option is limited to the interest earned on the liquid assets securing the put option plus the premium received from the purchaser of the put option, the Fund risks a loss equal to the entire value of the stock.

 

•If a put option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price, the Fund will lose its entire investment in the option.

 

The Fund’s options transactions will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities on which such options are traded. The number of options which the Fund may write or purchase may be affected by options written or purchased by other clients of Madison or its affiliates.

Madison Covered Call & Equity Income Fund | Tax Risk [Member]

Tax Risk. The Fund will generate taxable income and therefore is subject to tax risk. In addition to option premium income, most or all of the gains from the sale of the underlying securities held by the Fund on which options are written may be short-term capital gains taxed at ordinary income rates in any particular year. Because the Fund does not have control over the exercise of the call options it writes, such exercises or other required sales of the underlying stocks may force the Fund to realize capital gains or losses at inopportune times. The Fund’s transactions in options are subject to special and complex U.S. federal income tax provisions that may, among other things, treat dividends that would otherwise constitute qualified dividend income as non-qualified dividend income; treat dividends that would otherwise be eligible for the corporate dividends-received deduction as ineligible for such treatment; disallow, suspend or otherwise limit the allowance of certain losses or deductions, (iv) convert lower taxed long-term capital gain into higher taxed short-term capital gain or ordinary income; convert an ordinary loss or deduction into a capital loss (the deductibility of which is more limited); and cause the Fund to recognize income or gain without a corresponding receipt of cash.

Derivatives Risk. The risk that loss may result from investments in options, forwards, futures, swaps and other derivatives instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party to the transaction will not fulfill its contractual obligations.

Mid Cap Risk. The Fund’s investments in midsize companies may entail greater risks than investments in larger, more established companies. Mid-capitalization companies tend to have narrower product lines, fewer financial resources, and a more limited trading market for their securities, as compared to larger companies. They may also experience greater price volatility than securities of larger capitalization companies because growth prospects for these companies may be less certain and the market for such securities may be smaller. Some growth-oriented companies may not have established financial histories; often have limited product lines, markets, or financial resources; may depend on a few key personnel for management; and may be susceptible to losses and risks of bankruptcy.

Interest Rate Risk. To the extent the Fund invests in fixed income securities (i.e., bonds), the Fund will be subject to interest rate risk, which is the risk that the value of your investment will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the market value of income-bearing securities. When interest rates rise, bond prices fall; generally, the longer a bond’s maturity, the more sensitive it is to this risk.

Depository Receipt Risk. Depository receipts, such as ADRs, global depository receipts (“GDRs”), and European depository receipts (“EDRs”), may be issued in sponsored or un-sponsored programs.  In a sponsored program, a security issuer has made arrangements to have its securities traded in the form of depository receipts.  In an un-sponsored program, the issuer may not be directly involved in the creation of the program.  Depository receipts involve many of the same risks as direct investments in foreign securities.  These risks include, but are not limited to, fluctuations in currency exchange rates, which are affected by international balances of payments and other financial conditions; government interventions; and speculation.  With respect to certain foreign countries, there is the possibility of expropriation or nationalization of assets, confiscatory taxation, political and social upheaval, and economic instability.  Investments in depository receipts that are traded over the counter may also be subject to liquidity risk.
