Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. You may qualify for sales charge discounts on Class A shares if you or your family invest, or agree to invest in the future, at least $25,000 in the Fund’s Class A shares. Certain financial intermediaries may also offer variations in Fund sales charges to their customers as described in Appendix A to the Prospectus. More information about these and other discounts is available from your financial professional and under “Shareholder Information – Class A Sales Charge Reductions and Waivers” beginning on page 15 of this Prospectus, in Appendix A to the Prospectus, and under “Sales Charges; Sales Charge Reductions and Waivers – Sales Charges on Class A Shares” beginning on page 37 of the Fund’s Statement of Additional Information (“SAI”).

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 transaction costs and potentially higher taxes, which are not reflected in the Total 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 17.53% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then hold or redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The operating expense limitation agreement discussed in the table above is reflected only through June 28, 2025.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Fund invests at least 80% of its net assets in the equity securities of companies that pay current dividends and that the Fund’s portfolio managers believe have the potential to increase their dividends with regularity.

Equity securities in which the Fund invests consist primarily of common stocks, but may also include master limited partnerships (“MLPs”) and real estate investment trusts (“REITs”). MLPs are businesses organized as limited partnerships that trade their proportionate shares of the partnership (units) on a public exchange. A REIT is a security of a company that invests in real estate, either through real estate property, mortgages and similar real estate investments, or all of the foregoing. The Fund will invest primarily in securities of U.S. companies, but may invest up to 20% of its net assets in securities of “foreign issuers.” “Foreign issuers” means non-U.S. companies: (a) whose securities are traded on a U.S. exchange, and denominated in U.S. dollars, in the form of American Depositary Receipts (“ADRs”); or (b) who are organized and headquartered outside the United States but whose securities are publicly traded on a U.S. exchange.

The Fund invests in companies in numerous market sectors and with various market capitalizations. The portfolio managers expect to invest mainly in large-capitalization companies (those with market capitalizations of $10 billion and higher), but may also invest in medium-capitalization companies (market capitalizations of $2 billion to $10 billion) and small-capitalization companies (market
capitalization of less than $2 billion). The Fund will generally remain fully invested, and under normal market conditions, the Fund’s portfolio will consist of approximately 30 to 80 companies.

In selecting investments for the Fund’s portfolio, the Adviser utilizes a bottom-up approach, focusing on fundamental qualities of individual companies. The Adviser believes that consistent earnings growth drives consistent dividend growth. Over the long run, the Adviser believes consistent earnings growth will help the price performance of a stock. Thus, the Fund’s portfolio managers begin with companies with well-established records of consistent earnings and dividend growth. Income created by rising common stock dividends is an important consideration in selecting the Fund’s investments.
The Fund’s portfolio managers will generally sell a security when they believe a company’s dividend growth potential is in jeopardy, when a company’s fundamentals are likely to deteriorate, when a company’s valuation becomes excessive, when a better investment opportunity becomes available or in order to meet shareholder redemptions.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Remember, in addition to possibly not achieving your investment goals, you could lose money by investing in the Fund.
Dearborn Partners Rising Dividend Fund | Recent Market Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Recent 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, armed 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.
Dearborn Partners Rising Dividend Fund | Strategy Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Strategy Risk. There is no guarantee that the issuers of the stocks held by the Fund will declare dividends in the future, or that if dividends are declared, they will remain at their current levels or increase over time. The Fund’s performance during a broad market advance could suffer because dividend paying stocks may not experience the same capital appreciation as non-dividend paying stocks. Depending upon market conditions, dividend paying stocks that meet the Fund’s investment criteria may not be widely available, making it difficult for the Adviser to replace stocks that have decreased or eliminated dividend payments.
Dearborn Partners Rising Dividend Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Management Risk. The Adviser’s judgments about the attractiveness, value and potential appreciation of the Fund’s investments may prove to be incorrect and the investment strategy employed by the Adviser in selecting investments for the Fund may not result in an increase in the value of your investment or in overall performance equal to other similar investment vehicles having a similar investment strategy.
Dearborn Partners Rising Dividend Fund | Common Stock Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Common Stock Risk. Common stock represents a proportionate share of the ownership of a company and its value is based on the success of the company’s business, any income paid to stockholders, the value of its assets, and general market conditions. In addition to the general risks of equity securities, investments in common stocks are subject to the risk that in the event a company in which the Fund invests is liquidated, the holders of preferred stock and creditors of that company will be paid in full before any payments are made to the Fund as a holder of common stock. It is possible that all assets of that company will be exhausted before any payments are made to the Fund.
Dearborn Partners Rising Dividend Fund | Large-Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Large-Capitalization Company Risk. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in consumer tastes or innovative smaller competitors. Also, large-capitalization companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.
Dearborn Partners Rising Dividend Fund | Small- And Mid-Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small- and Medium-Capitalization Companies Risk. Investing in securities of small- and medium-capitalization companies may involve greater volatility than investing in larger and more established companies because small- and medium-capitalization companies can be subject to more abrupt or erratic share price changes than larger, more established companies.
Dearborn Partners Rising Dividend Fund | REIT Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock REIT Risk. Adverse changes in general economic and local market conditions, supply or demand for similar or competing properties, taxes, governmental regulations or interest rates, as well as the risks associated with improving and operating property, may decrease the value of REITs in which the Fund may invest. In addition, to the extent the Fund holds interests in REITs, it is expected that investors in the Fund will bear two layers of asset-based management fees and expenses (directly at the Fund level and indirectly at the REIT level). Additionally, there is always a risk that a REIT will fail to qualify for favorable tax treatment.
Dearborn Partners Rising Dividend Fund | MLP Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock MLP Risk. MLP investment returns are enhanced during periods of declining or low interest rates and tend to be negatively influenced when interest rates are rising. In addition, most MLPs are fairly leveraged and typically carry a portion of a “floating” rate debt. As such, a significant upward swing in interest rates would also drive interest expense higher. Furthermore, most MLPs grow by acquisitions partly financed by debt, and higher interest rates could make it more difficult to make acquisitions. MLP investments also entail many of the general tax risks of investing in a partnership. Limited partners in a MLP typically have limited control and limited rights to vote on matters affecting the partnership. Additionally, there is always the risk that a MLP will fail to qualify for favorable tax treatment.
Dearborn Partners Rising Dividend Fund | Foreign Securities and ADR Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Securities and ADR Risk. The Fund’s investments in securities of foreign companies, including in the form of ADRs, are subject to risks relating to political, social and economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices, including fluctuations in foreign currencies. ADRs are securities representing the securities of foreign issuers. A purchaser of unsponsored depositary receipts may not have unlimited voting rights and may not receive as much information about the issuer of the underlying securities as with a sponsored depositary receipt. Income earned on foreign stocks and securities may be subject to foreign withholding taxes.
Dearborn Partners Rising Dividend Fund | Cybersecurity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

[3] Pursuant to an operating expense limitation agreement between Dearborn Partners, L.L.C., the Fund’s investment adviser (the “Adviser”), and the Trust, on behalf of the Fund, the Adviser has agreed to waive its management fees and/or reimburse Fund expenses to ensure that Total Annual Fund Operating Expenses (exclusive of front-end or contingent deferred loads, Rule 12b-1 plan fees, shareholder servicing plan fees, taxes, leverage expenses (i.e., any expenses incurred in connection with borrowings made by the Fund), interest (including interest incurred in connection with bank and custody overdrafts), brokerage commissions and other transactional expenses, expenses incurred in connection with any merger or reorganization, dividends or interest expenses on short positions, acquired fund fees and expenses or extraordinary expenses such as litigation (collectively “Excluded Expenses”) do not exceed 0.95% of the Fund’s average daily net assets, through at least June 28, 2025, and subject thereafter to annual re-approval of the agreement by the Trust’s Board of Trustees (the “Board of Trustees”). To the extent the Fund incurs Excluded Expenses, Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement may be greater than 0.95%. The operating expense limitation agreement may be terminated only by, or with the consent of, the Board of Trustees. The Adviser may request recoupment of previously waived fees and paid expenses from the Fund up to three years from the date such fees and expenses were waived or paid, subject to the operating expense limitation agreement, if such reimbursement will not cause the Fund’s expense ratio, after recoupment has been taken into account, to exceed the lesser of: (1) the expense
limitation in place at the time of the waiver and/or expense payment; or (2) the expense limitation in place at the time of the recoupment.
