I have an ag-grid with all columns defined in two groups and the column tool panel on. Currently when you open the tool panel, it keeps both groups expanded but I would like to by default keep one of them collapsed and the other expanded. Is this possible? I wasn't able to find a function in the ag-grid API to do this.
EDIT
The first example here shows the column groups in a tool panel: https://www.ag-grid.com/javascript-grid-tool-panel-columns/
I want to make the column groups "Athlete" and "Competition" collapsed by default in the tool panel but leave "Medals" expanded.
