Dear Richard @Richard-Keith
Thanks a lot!
I have tried it, in principle it works:
At least the first time. As soon as I click on one of the two pages, all menu items disappear.
They reappear when I'm out of the page area (firefox menu or similar).
On mobile the mouseover makes no sense, of course,
so i wrote it into the desktop CSS for testing.
But the tablet case is not yet covered.
Is there a possibility for this.
A pure certain screen size or something?
Best regards
Stefan
