Can’t edit a row without adding a new row

[pierrelouis_p]

Hello,

I have a row with a dropdown list to select an item (in example here a work report).

I want the user edit the row without adding a new row.
But i can’t even if “update” is “on” inside “Data”

Thanks in advance for your help!

Edit : It’s just the tick box “key” !!
