Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund invests primarily in U.S. common stocks. In selecting securities for the Fund, the Fund’s investment adviser, Mairs & Power, Inc. (the Adviser), gives preference to companies that exhibit the potential for above-average growth and durable competitive advantages at reasonable valuations. In the Adviser’s experience, these securities typically have strong returns on invested capital. The Adviser follows a multi-cap approach and the Fund invests in stocks of small-cap, mid-cap and large-cap companies. The Adviser focuses generally on companies located in Minnesota and other states in the Upper Midwest region of the U.S. (which the Adviser considers to be the states of Illinois, Iowa, Minnesota, North Dakota, South Dakota and Wisconsin). The Fund may also invest up to 25% of its total assets in securities of foreign issuers which are listed on a U.S. stock exchange or are represented by American Depositary Receipts (ADRs). The Fund may have significant investments in the industrials, information technology and healthcare sectors. The Adviser seeks to keep the Fund’s assets reasonably fully invested, to maintain modest portfolio turnover rates and to moderate risk by investing in a diversified portfolio of equity securities.

The Adviser may sell the Fund’s portfolio securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.

The following bar chart and table illustrate the risks of investing in the Fund. The bar chart shows changes in the Fund’s performance from year to year over a 10-year period. Both the chart and the table assume that all distributions have been reinvested. The Fund is the successor to the Mairs & Power Growth Fund, a series of Mairs & Power Funds Trust (the Predecessor Growth Fund). The returns presented reflect the historical performance of the Predecessor Growth Fund for the periods from prior to April 29, 2022. The Fund has adopted the performance of the Predecessor Growth Fund as a result of a reorganization in which the Fund acquired all the assets and liabilities of the Predecessor Growth Fund (the Reorganization) which occurred on April 29, 2022. Prior to the Reorganization, the Fund had not commenced operations. The Predecessor Growth Fund had the same Adviser, investment objectives and strategies as the Fund.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Minnesota/Upper Midwest Geographic Risk
The Adviser focuses generally on securities of companies that are located in the Upper Midwest region of the U.S. The Fund typically emphasizes companies located in Minnesota, in particular. The Fund may be impacted by events or conditions affecting the region to a greater extent than if the Fund invested in more geographically diverse investments. For example, political and economic conditions and changes in regulatory, tax or economic policy in a state or region could affect the economy or particular business operations of companies located in the state or region.
Mairs & Power Growth Fund | Recent Market Events Risk; General Market Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Recent Market Events Risk; General Market Events Risk
U.S. and international markets have experienced and may continue to experience significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including uncertainty regarding inflation and central banks’ interest rate increases, the possibility of a national or global recession, trade tensions, political events, the war between Russia and Ukraine, significant conflict between Israel and Hamas in the Middle East, and the impact of the coronavirus (COVID-19) global pandemic. The impact of COVID-19 may last for an extended period of time. As a result of continuing political tensions and armed conflicts, including the war between Ukraine and Russia, the U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so. Continuing market volatility as a result of recent market conditions or other events may have an adverse effect on the performance of the Fund.

Convertible Debt Securities Risk
Convertible securities are fixed income securities that the Fund has the option to exchange for equity securities at a specified conversion price. Consequently, the value of the convertible security may be exposed to the market risk of the underlying stock, interest rate risk and the credit risk of the issuer.

Risk [Text Block] rr_RiskTextBlock
Debt Securities Rated Less than Investment-Grade Risk
These securities have a higher degree of credit risk than investment-grade securities. Companies that issue these lower rated securities (also known as “high yield” or “junk bonds”) are often highly leveraged and traditional methods of financing may not be available to them. Also, market values of lower rated securities may be more sensitive to developments which affect the individual issuer and to general economic conditions.
Mairs & Power Balanced Fund | Fixed Income Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Fixed Income Risk
Risks related to fixed income investments include credit risk, interest rate risk, prepayment risk, extension risk and call risk, among others. Credit risk is the risk that the issuer of a debt security will fail to make interest and principal payments when due. Interest rate risk is the risk that the value of a fixed-rate debt security will decline due to an increase in market interest rates. A fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration. For example, the market price of a debt security with a duration of four years would be expected to fall approximately 4% if interest rates rose by one percentage point immediately. Prepayment risk is the risk that in times of declining interest rates, the Fund’s higher yielding securities will be prepaid and the Fund will have to replace them with securities having a lower yield. Extension risk is the risk that in times of rising interest rates, prepayments will slow causing portfolio securities
considered short or intermediate term to be long-term securities, which fluctuate more widely in response to changes in interest rates than shorter term securities. Call risk is the risk that an issuer, especially during a period of falling interest rates, may call (redeem) a security by repaying it early, which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates.

No assurance can be given that the U.S. Government will provide financial support to U.S. government-sponsored agencies or instrumentalities where it is not obligated to do so by law, such as the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac). Securities issued by Fannie Mae and Freddie Mac have historically been supported only by the discretionary authority of the U.S. Government. While the U.S. Government provides financial support to various U.S. government-sponsored agencies and instrumentalities, such as Fannie Mae and Freddie Mac, no assurance can be given that it will always do so.

The Fund may be impacted by events or conditions affecting the region to a greater extent than if the Fund invested in more geographically diverse investments. For example, political and economic conditions and changes in regulatory, tax or economic policy in a state or region could affect the economy or particular business operations of companies located in the state or region.

The impact of COVID-19 may last for an extended period of time. As a result of continuing political tensions and armed conflicts, including the war between Ukraine and Russia, the U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so. Continuing market volatility as a result of recent market conditions or other events may have an adverse effect on the performance of the Fund.

There are certain risks in securities of foreign issuers which are not associated with domestic securities. These risks, among others, include political, social or economic instability, difficulty in predicting international trade patterns, taxation and foreign trading practices, and greater fluctuations in price than U.S. corporations. In addition, there may be less publicly available information about a foreign company than about a U.S. domiciled company.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund normally will invest at least 80% of its net assets (including borrowings for investment purposes) in U.S. common stocks issued by small-cap companies. For this purpose, small-cap companies are defined as companies whose market capitalization at the time of purchase is within the market capitalization range represented by companies in the S&P SmallCap 600® Total Return Index. The S&P SmallCap 600® Total Return Index is a widely used benchmark for small-cap performance and is rebalanced continuously. As of December 31, 2023, the market capitalization range for the S&P SmallCap 600® Total Return Index was approximately $433.2 million to $8.2 billion, but is expected to change frequently. The Fund also may invest in common stocks issued by companies with market capitalizations above the market capitalization range of the S&P SmallCap 600® Total Return Index only if, after the purchase is made, the Fund has at least 80% of its net assets invested in small-cap securities.

In selecting securities for the Fund, the Fund’s investment adviser, Mairs & Power, Inc. (the Adviser), gives preference to companies with attractive business niches, strong competitive positions, and the potential to grow revenues, earnings and cash flows consistently over the long-term. Capable management with a track record of prudent capital deployment is also an important consideration. The Adviser focuses generally on companies located in Minnesota and other states in the Upper Midwest region of the U.S. (which the Adviser considers to be the states of Illinois, Iowa, Minnesota, North Dakota, South Dakota and Wisconsin). The Fund may also invest up to 25% of its total assets in securities of foreign issuers which are listed on a U.S. stock exchange or are represented by American Depositary Receipts (ADRs). From time to time, the Fund may invest in initial public offerings (IPOs). The Fund may have significant investments in the industrials sector. The Adviser seeks to keep the Fund’s assets reasonably fully invested, to maintain modest portfolio turnover rates, and to moderate risk by investing in a diversified portfolio of equity securities.

The Adviser may sell the Fund’s portfolio securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.

The following bar chart and table illustrate the risks of investing in the Fund. The bar chart shows changes in the Fund’s performance from year to year over a 10-year period. Both the chart and the table assume that all distributions have been reinvested. The Fund is the successor to the Mairs & Power Small Cap Fund, a series of Mairs & Power Funds Trust (the Predecessor Small Cap Fund). The returns presented reflect the historical performance of the Predecessor Small Cap Fund for the periods prior to April 29, 2022. The Fund has adopted the performance of the Predecessor Small Cap Fund as a result of a reorganization in which the Fund acquired all the assets and liabilities of the Predecessor Small Cap Fund (the Reorganization) which occurred on April 29, 2022. Prior to the Reorganization, the Fund had not commenced operations. The Predecessor Small Cap Fund had the
same Adviser, investment objectives and strategies as the Fund. Visit the Fund’s website at www.mairsandpower.com, or call 800-304-7404 for current performance figures. Past performance of the Fund, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

The Fund may invest in initial public offerings by small-cap companies, which can involve greater risks than investments in companies which are already publicly traded. The companies which undergo IPOs generally have limited operating histories, and their prospects for future profitability are uncertain. In addition, stock prices of IPOs can be highly unstable due to the absence of a prior public market and other factors.

Recent Market Events Risk; General Market Events Risk
U.S. and international markets have experienced and may continue to experience significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including uncertainty regarding inflation and central banks’ interest rate increases, the possibility of a national or global recession, trade tensions, political events, the war between Russia and Ukraine, significant conflict between Israel and Hamas in the Middle East, and the impact of the coronavirus (COVID-19) global pandemic. The impact of COVID-19 may last for an extended period of time. As a result of continuing political tensions and armed conflicts, including the war between Ukraine and Russia, the U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so.

Small-Cap Securities Risk
Generally, companies with smaller market capitalizations have fewer shares traded daily, less liquidity, and greater price volatility than companies with larger market capitalizations. In addition, small-cap companies tend to have shorter track records, a more limited product or service base, more limited access to capital, and a greater possibility of failing. These factors increase the risk of investing in small-cap companies, as compared to mid-cap and large-cap companies.
