Fot the navigation list styling (this one right? https://atlas.mendix.com/p/widget_navigationlist/5910974510924180)
you need to put the element in a container which has 'profile-phone' as class. Fur further styling I'd just inspect the element on the example page and copy the css :)
That is not the answer I was looking for. Probably there is no pre-defined class for this layout, because I cannot find the same navigation layout in the Atlas UI reference project.
