This way it is unusable for my customer due to long titles. The layer opens to the right and is visible until level 2 and than no navigation to deeper levels is possible, as when trying to reach the horizontal scrollbars the layers disapear.

Someone with an idea where to change this behaviour?
Ty in advance!
