Reply To: nested grid inside a tree grid

[Oleg Ilin]

Dear Svetoslav.
Thank so much you for your help.
Is it possible:
1 Combine both arrows into one (so that the row details grid expands when the parent node is opened).
In another way, when clicking on the arrows, either a new category or details about the line was programmed to open.
2 Hide some (not all)  selective arrows so as not to show the details of those rows ?
Best Regards
Oleg Il
