Place the dropdown icon before the text in DOM to fix this. See

[mvorisek]

That breaks the 1st level arrow/icon then:

(it is generated with the same template - https://github.com/atk4/ui/blob/5.2.0/template/submenu.html#L3 )

But the first icon is the dropdown item itself, while all sub menu items should only be items containing another menu, not another dropdown items, so they should not share the same template. Thats why i also removed the "ui dropdown" class from the sub menu item
