CK Mobile not work on mobile phones portrait mode

ok I have seen
go in the module >> advanced options >> css suffix >> add " maximenuck"
then tell me

I could not see in advanced options css suffix (see screen shot)
I can only see Module class suffix which I added 'maximenuck'.
The only thing that did was change the layout of menu displayed (in landscape format)
I still cannot see it in Portrait format.
Am I in the wrong options?

Kind regards

I don't see the suffix applied to your menu , in the module ID 443
please put it again and tell me, don't forget the space at the beginning
" maximenuck"

Ok,
That seems to work when I test it. Can you tell me why that option is important and when I should use it?
Thank you for your help with this.

ok, this is because you are using the "nativejoomla" layout and not the default one
if you want to use this layout with he mobile, you must add this css class
I don't add it by default to not disturb the layout for all users
