Hi Zoltan,
I've tested here with example 3, by putting a tooltip on the drop-down on the "AliasFormControl" procedure.
Unfortunately it seems to be working though. (At least for me.) So I thought it might be the "width" paramater which affects it, but no, it seems to work then as well.
So check out example 3, add a tip to the drop-down, and see what happens on your side. If it works there, then I guess I need an example from you where it's not working.
Cheers
Bruce
Ps - I'm testing with PR24, but nothing has changed with drop-downs for a while, so I don't think that's the issue.
