I am not sure how the combo filter works in layouts...
I can't drag any field inside it.
Is it a bug of the interface, a disabled functionnality or I am missing something ?
Can you describe or point to the doc for this particular point ?
Thanks

Select do not accept all types of datas (only FK, enums, boolean)
You cannot instance 2 filters for the same field. (you can see a red highlight if it is the case)

I think maybe a little bug if you have already instancied this field in the search (wich is of course possible in that case)

If the droppable zone border highlight in red ?
Do you have a JS issue ?

OK this clarify the point. The droppable zone stay gray. No JS issue.


(I realize I do not select the right forum for this.. there is no way to change.. )
