Hi Rikard, thanks very much for your help!
I have solved the problem, by doing a change from the style of the sidebar flyout menu to of full! page widht now.
That looks good, or even better than before, because before (as it was seen) there was the menu only narrow.
I believe, this is a problem of the widht of the text, maybe it is more hide on a side, and therefore you cant see it on the narrow smartphone burger menu. …
The only thing wich is not perfect now is, that you can see the hole Menu with white text , and therefore you can not choose, wich one is active. I mean you see also the bold Mega Menu (like: TRAURINGE) , and the user can not open it, wich is ok, but the user thinks maybe, he can open nothing. He can open the deeper lying pages- of course, if he try, but he can not the active sides apparently. Per example as different colors , or a lightning text of the pages wich are active.
best regards back -Mattis
