Risk/Return, Heading rr_RiskReturnHeading SUMMARY SECTION
Investment Objective, Heading rr_ObjectiveHeading Investment Objective.
investment Objective, Primary rr_ObjectivePrimaryTextBlock 
The investment objective of the Frontegra SAM Global
Equity Fund (the "Fund") is long-term growth of capital.
Expense, Heading rr_ExpenseHeading Fees and Expenses of the Fund.
Expense, Narrative rr_ExpenseNarrativeTextBlock 
This table describes the fees and expenses that
you may pay if you buy and hold shares of the Fund.
Shareholder Fees, Caption rr_ShareholderFeesCaption Shareholder Fees (fees paid directly from your investment) NONE
Operating Expenses, Caption rr_OperatingExpensesCaption Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover, Heading rr_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover 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 its most recent fiscal year, the Fund's predecessor, the SAM Sustainable
Global Active Fund (the "SAM Fund"), had a portfolio turnover rate of 88% of
the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 88.00%
Other Expenses, New Fund, Based on Estimates rr_OtherExpensesNewFundBasedOnEstimates "Other Expenses" are based on estimated amounts for the current fiscal year.
Expense Example, Heading rr_ExpenseExampleHeading Example.
Expense Example, Narrative rr_ExpenseExampleNarrativeTextBlock 
The following example is intended to help you compare the cost of investing
in the shares of 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 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.
Expense Example, By Year, Caption rr_ExpenseExampleByYearCaption Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Investment Strategy, Heading rr_StrategyHeading Principal Investment Strategy.
Investment Strategy, Narrative rr_StrategyNarrativeTextBlock 
Under normal circumstances, the Fund invests at least 80% of its net assets
(including any borrowings for investment purposes) in a non-diversified portfolio
of equity and equity-related securities issued by U.S. and non-U.S. companies that
combine their market and financial strategy with a high level of environmental
awareness and a clearly defined social policy ("Sustainable Issuers").  As part
of its principal investment strategy, the Fund may invest in securities of foreign
companies, including emerging markets companies, and companies with medium and small
market capitalizations, including micro-cap stocks.
Risk, Heading rr_RiskHeading Principal Investment Risks.
Risk, Narrative rr_RiskNarrativeTextBlock 
Market Risks.  The Fund's investments are subject to market risk, which may
cause the value of the Fund's investments to decline.  If the value of the
Fund's investments goes down, the share price of the Fund will go down, and you
may lose money.  U.S. and international markets have experienced extreme
volatility, reduced liquidity, credit downgrades, increased likelihood of
default and valuation difficulties in recent years.

Foreign Securities Risks.  The Fund's foreign investments involve additional
risks, including less liquidity, currency-rate fluctuations, political and
economic instability and differences in financial reporting standards and
securities market regulation.

Emerging Markets Risks.  The risks of foreign investments typically are greater
in emerging markets due to factors such as smaller securities markets and lower
trading volumes, less developed legal and accounting structures, substantial
influence by an emerging market country's government over the private sector and
potential high levels of inflation, deflation or currency devaluations.

Non-Diversification Risks.  The Fund is non-diversified, which means it may
invest more of its assets in a smaller number of companies than funds that are
diversified.  Gains or losses on a single stock may have greater impact on the
Fund than for other funds that invest in a greater number of companies.

Sustainability Investment Criteria Risks.  The Fund's sustainability investment
criteria may limit the number of investment opportunities available to the Fund.
The Fund's returns may be less than those funds that are not subject to such
investment considerations.  Companies that promote sustainability goals may not
perform as well as companies that do not pursue such goals.

Currency Risks.  The value of the Fund's foreign securities as measured in U.S.
dollars may be affected unfavorably by changes in foreign currency exchange
rates.  The Fund may also incur costs in connection with conversions between
various currencies.

Small- and Medium-Capitalization Company Risks.  Small-capitalization and
medium-capitalization companies are often more volatile and less liquid than
larger companies.  Securities of these companies may be subject to greater and
more abrupt price fluctuations and be more susceptible to market pressures and
business failures.  The Fund may invest in small-capitalization companies whose
securities may be traded only in the over-the-counter market or on a regional
exchange, and may not trade with the frequency or volume typical of trading on a
national exchange.

Micro-Capitalization Company Risks.  Micro-capitalization companies are
generally even more volatile and less liquid relative to small-capitalization,
medium-capitalization and large capitalization securities.

Management Risks.  The Fund is subject to management risk as an actively-managed
investment portfolio and depends on the decisions of the portfolio managers to
produce the desired results.
Risk, Lose Money rr_RiskLoseMoney If the value of the Fund's investments goes down, the share price of the Fund will go down, and you may lose money.
Risk, Nondiversified Status rr_RiskNondiversifiedStatus The Fund is non-diversified, which means it may invest more of its assets in a smaller number of companies than funds that are diversified. Gains or losses on a single stock may have greater impact on the Fund than for other funds that invest in a greater number of companies.
