I'm developing an admin grid for my custom module with the inlineEdit active instead of the usual edit link in action column.
The grid works fine and also the inlineEdit works as intended.
My only question is about the "all in column" field that appears when I'm in edit line mode.
I cannot understand what this field is for. If I write something in this field, the "save edits" button become disabled so I cannot save anything.
So what's this field for?
