While programming a typo3 extension I came across the following problem: my backend module didn’t show any scrollbars. This made it impossible to scroll down to the end of a list to view all elements.
After some looking around I found the CSS class typo3-mod-php which has set the property „overflow“ to „hidden“. Seems to be ONE of the bad one to me. I don’t think it is the only reason.
To fix the problem for me I added following code to the moduleContent() method in my backend module:
$content .= „
It’s not perfect, but it’ll have to fit until I have found something better.
