This works. Thank you very much,Tom for your brilliant service.
But could you tell me how i can find out this myself. I use Inspect Element but this I couldn’t find.
Another little problem: The update changed also the margin/padding between the witgets. In the settings I put Row Gutter and Row Bottom Margin on 0px but no reaction.
