That metamenu are two menus.

left side: "...us de Schwiiz Contact" are normal menu to pages
right side is a language menu (special = language)

Easy to define in typoscript. As you can see in the HTML of that page the menus are seperate HTML blocks (<nav>) and the language menu comes first (->floating)
