Thank you for your response. But the "onlymobile" module class suffix application does not remove language switch for desktop devices.
The class is added to the embedded "div" element. If you add this class to the parent "div" element (id="gkLang") manually in the Developer tools, all works well.
Actually, a question:
- how to add "onlymobile" module class suffix to the parent item in the backend?
Additional question:
- is it possible to use the module class suffix "onlydesktop" for the menu item, or something like that?
