Hi Marc,
Hi, looking at your wire frame, I fail to see how one would expand/collapse the search criteria when there are search results on-screen, which is the feature that is present in table search in current master.
Also I don't understand how the Column section would be used.
I realize that I interpreted your idea in a wrong way. I saw the "Show search criteria" option just now. I got the idea well. Sorry for the inconvenience you faced. Thank you.
Regards, Thilanka.
