Hi @Ram_Ch , you can first define your list like below:
dropdownlst = (‘A’, ‘B’, ‘C’)
And then configure the column like below:
gb.configure_column(“Your Col Name”, editable=True, cellEditor=‘agSelectCellEditor’, cellEditorParams={‘values’: dropdownlst })
When you double-click on any cell in that column, the dropdown list should appear and be choosable.
Cheers
