question accepted - but actually for my case irrelevant.
a) I need to have this option on ONE column only - that's enough. So actually, I would need to define which column needs this function.
I agree, that it's nice, that one can click on any column, but this "one" column should have a different behavior.
As the application will be used mostly on tablets, it would be easier (in my context and customer asked for this) if one could search for description and then click on an Area to see all items in that are - instead of setting up a filter (general filter is too specific, search page maker does not create a search for my field as it is Autofill (see viewtopic.php?f=11&t=3041
b) the user can only edit that one column. No other details are shown when an item is selected.
I though maybe putting a link on that item in the media section - but this does not seem to be an option (see screenshot).
Maybe it would be of some help already, if there is a way to create a filter with a link ( viewtopic.php?f=2&t=3051
). This way, I could probably tweak the table output to include that link instead of a link to details.
