I have already tried this.
However, the mega menu is created based on the category structure and not the menu structure.

The mega menu should only contain what is in the menu.

in Geman:
Das habe ich bereits probiert.
Das Mega Menü wird aber anhand der Kategoriestruktur erstellt und nicht anhand der Menüstruktur.

Kategoriestruktur:

Es soll im Megamenü nur das stehen, was auch im Menü steht.

So there is no way to only display the 2nd level of categories as Text under the images?
I would like only the subcategories (2nd level) to be displayed as text under the images.
the sub(under) categories (level2) but not(3rd level).
Example:
>>Main category*select as megamenü(level1)
>>>>3xsubcategories
(level2)*shown as Text under picture
>>>>>>3xsubcategory(levele3)*not displayed as Text under picture
