I am using react grid group feature. But it shows groups expanded by default.
I didn't found any way to show it collapsed by default.
The expand/collapse state of the groups is part of the data and controlled by the value of the field set in the expandField prop:https://www.telerik.com/kendo-react-ui/components/grid/api/GridProps/#toc-expandfieldIf all groups have to be collapsed, I can suggest to loop over the data and set the expanded field of all records to false. This is an example showcasing it:https://stackblitz.com/edit/react-gmfcy6?file=app/main.jsAs the groups can be nested on many levels, the example only covers the first level, but it can be done recursively to cover N number of group levels if needed.I hope this is helpful.
