| Performance Narrative [Text Block] | The bar chart and the performance table below illustrate the risks and volatility of an investment in the Fund by showing changes in the Fund’s Class A shares’ performance from year to year for the past 10 years and by showing how the Fund’s Class A shares’ and Class Y shares’ average annual total returns for 1, 5 and 10 years compare with those of a broad measure of market performance. The bar chart does not reflect the deduction of applicable sales charges for Class A shares. If sales charges had been reflected, the returns for Class A shares would be less than those shown below. Of course, the Fund’s past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.
The Fund operated as the Highland Fixed Income Fund (the “Predecessor Fixed Income Fund”) prior to the Fund’s acquisition of the assets and liabilities of the Predecessor Fixed Income Fund on January 11, 2021 (the “Fixed Income Fund Reorganization”). As a result of the Fixed Income Fund Reorganization, the Fund assumed the performance and accounting history of the Predecessor Fixed Income Fund prior to the date of the Fixed Income Fund Reorganization. Accordingly, the performance shown for periods prior to the Fixed Income Fund Reorganization represents the performance of the Predecessor Fixed Income Fund. The Predecessor Fixed Income Fund’s returns in the bar chart and table have not been adjusted to reflect the Fund’s expenses. If the Predecessor Fixed Income Fund’s performance information had been adjusted to reflect the Fund’s expenses, the performance may have been higher or lower for a given period depending on the expenses incurred by the Predecessor Fixed Income Fund for that period.

As a result of the Total Return Fund Reorganization, the Fund assumed the performance and accounting history of the Predecessor Total Return Fund prior to the date of the Total Return Fund Reorganization.

If the Predecessor Total Return Fund’s performance information had been adjusted to reflect the Fund’s expenses, the performance may have been higher or lower for a given period depending on the expenses incurred by the Predecessor Total Return Fund for that period.
The Predecessor Total Return Fund’s performance prior to February 1, 2015 reflects returns achieved when the Predecessor Total Return Fund was sub-advised by a different sub-adviser. If the Predecessor Total Return Fund’s latter management had been in place for the periods prior to February 1, 2015, the performance information shown for such periods would have been different.

Of course, the Fund’s past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.
Retail Shares had not commenced operations as of the date of this prospectus. Therefore, performance information for Retail Shares is not presented. Retail Shares would have substantially similar performance as Institutional Shares because the shares are invested in the same portfolio of securities and the returns would generally differ only to the extent that expenses of Retail Shares are higher than the expenses of Institutional Shares, in which case the returns for Retail Shares would be lower than those of Institutional Shares.

Class N Shares had not commenced operations as of the date of this prospectus. Therefore, performance information for Class N Shares is not presented. Class N Shares would have substantially similar performance as Institutional Class Shares because the shares are invested in the same portfolio of securities and the returns would generally differ only to the extent that expenses of Class N Shares are higher than the expenses of Institutional Class Shares, in which case the returns for Class N Shares would be lower than those of Institutional Class Shares.

The Fund operated as the Ecofin Global Renewables Infrastructure Fund (the “Ecofin Predecessor Fund”), a series of Managed Portfolio Series, prior to the Fund’s acquisition of the assets and assumption of the liabilities of the Ecofin Predecessor Fund on September 30, 2024 (the “Reorganization”). The Reorganization closed effective September 30, 2024. As a result of the Reorganization, A Class Shares and Institutional Class Shares of the Fund assumed the performance and accounting history of A Class Shares and Institutional Class Shares of the Ecofin Predecessor Fund, respectively. In addition, A Class Shares and Institutional Class Shares of the Ecofin Predecessor Fund acquired the performance and accounting history of Tortoise Global Renewables Infrastructure Fund Limited (the “Tortoise Predecessor Fund” and together with the Ecofin Predecessor Fund, the “Predecessor Funds”), an unregistered Cayman Islands limited liability company, on August 7, 2020. Accordingly, performance figures for the periods prior to August 7, 2020, represent the performance of the Tortoise Predecessor Fund, and performance figures for the period from August 7, 2020 through September 29, 2024 represent the performance of the Ecofin Predecessor Fund. From its inception through August 7, 2020, the Tortoise Predecessor Fund was not subject to certain investment restrictions, diversification requirements and other restrictions of the 1940 Act, or Subchapter M of the Code, which, if they had been applicable, might have adversely affected the Tortoise Predecessor Fund’s performance. The Tortoise Predecessor Fund’s performance was calculated using a methodology of time-weighted total returns from official net asset values. Since August 7, 2020, the Predecessor Fund’s performance and the Fund’s performance have been calculated using the standard formula set forth in rules promulgated by the SEC, which differs in certain respects from the methods used to compute total return for the Tortoise Predecessor Fund.
The Predecessor Funds’ performance figures have not been adjusted to reflect the Fund’s expenses. If the Predecessor Funds’ performance information had been adjusted to reflect the Fund’s expenses, the performance may have been higher or lower for a given period depending on the expenses incurred by the applicable Predecessor Fund for that period.
