Joomla 5 Questions for positioning additional Menues

Hello,
I've migrated to Joomla 5 (from 3) and face some issues with positioning a second and third menu like in my Joomla 3 Version.
The "Custom position" has the same "Anchor" (#mobilemenuck-94-wrap) but now it is maybe influenced by the standard menu-size.
It appears below resolutions of 1000px. The Layout is Cassiopeia like before.

Problem Example:  borgmann-aquaponik-hydroponik.ch/pt2/ind...e/das-unternehmen-de

Previous Version works fine with 3 Menues:  borgmann-aquaponik-hydroponik.ch/po9d/index.php/en/

Cheers Helmer

CEd

Perfect !
It works !
Thank you very much !

I've purchased Menu-CK Pro a while ago but I do not see when it's licence expires. Anyway I buy right away a new licence to support you further a little bit.
Cheers, Helmer

great
for the licence, you can check in your joomlack.fr account, or use Extensions Manager CK in your website

Hello CEd,
I have another problem. As in the Joomla 3 version, the top menu is not visible. I have set up a Joomla 5 from scratch to see if my settings or the constellation are related to the menu. Also the addition that made the menu visible in Joomla 3 does not help. 
.mobilemenuck-submenu.hidden {
    visibility: visible;
}

Joomla 3 with menu in top line works well (The Company): 
borgmann-aquaponik-hydroponik.ch/po9d/index.php/en/

Joomla 5 : the menu at less then 1000px page width disappears and in the top line of the screen space is made for the Mobile-CK menu but it is not visible: 
borgmann-aquaponik-hydroponik.ch/pt2/index.php/de/artikel-de

Joomla 5 from scratch shows the same behavior: 
helmer-borgmann.ch/test/index.php/t2/t21

 
Do you have any idea?

Cheers, Helmer

ok, this is probably due to the layout selected for the mod_menu
please go in the advanced options of the module >> menu css suffix >> add " nav"

then check if it works
