I tried this code and this happened: (Screenshot down below) The menu sub items are shown in the header (visible only if marked) but not in the center. I tried to move it but no luck :(. I also need it in font color black and without this weird character in front of the items (Shown on the screenshot below).

And I don’t want that in the mobile Version of this Website. How can I prevent that it’s shown in the mobile version?

Thank you
