| Bar Chart and Performance Table [Heading] | Performance Information |
| Performance Narrative [Text Block] | As of the date of this Prospectus, the Fund does not have a full calendar year of performance as a mutual fund. Prior performance shown below is for the Core Predecessor Fund which commenced operations on November 20, 1995. The Fund has adopted the performance of the Core Predecessor Fund as a result of a reorganization in which the Fund acquired all the assets and liabilities of the Core Predecessor Fund (the “Reorganization”). Prior to the Reorganization, the Fund was a “shell” Fund with no assets and had not commenced operations. The Fund’s portfolio management team served as the portfolio management team of the Core Predecessor Fund and has been the Fund’s portfolio management team since inception. The bar chart and table that follow provide some indication of the risks of investing in the Fund by showing changes in its performance from year to year and how its average annual returns over various periods compare with those of an index that reflects a broad measure of market performance, as well as additional benchmarks that reflect the performance of investments similar to those of the Fund. For additional information on the indices, please see “Index Descriptions” in the Prospectus. The bar chart shows the performance of the Fund’s Retail Class Shares, and performance of the Fund’s Institutional Class Shares will differ from those shown to the extent that the classes of shares do not have the same expenses or inception date. Please remember that the Fund’s past performance (before and after taxes) is not necessarily an indication of its future performance. It may perform better or worse in the future. Updated performance information is available on the Fund’s website, https://funds.leutholdgroup.com/funds/48-leuthold-core-investment-fund.
