Thanks for your reply, yes, i read that in another post. But i build eyerything back to a minimum and there is still a double Scrollbar.
Look at the following example
https://zusammenfinden-sachsenheim.de/interviews/
The header is a single bar with a fix heigh, the content are only 2 sections with a row and a column without fixed height, the footer is only a bar with 3 buttons and a image and still there are 2 scrollbars.
The scrollbars are gone, when I delete a selection so that the height is not big enough to scroll, but that is of course no solution.
Best regards, Andreas
