Hi!
After seeing the “expandgroup” function, we wanted to add buttons in groupcolumnrenderer so a user could expand/collapse one column at a time. But look like I misunderstood how expandgroup works. I thought the index was the index of the groupcolumn, not the row.
I saw recents topics[1] where you say that the feature I’m looking for doesn’t exist (unless you added it recently?). But just to let you know that my company would use this feature if you develop it.
Regards
