I have the ver14. prof.

In the horisontal menu in the header you can make dropdown levels.

But when the browser is small we can only get to the menu true a button in the left or right side. So far so good.

The dropdown buttons is then coming inside the menu, between the other buttons. This make much confusion. A way to solve the problem is to let the dropdown come outside the hamburger:

As far as i know it is not possible today, but i hope this is possible in the future versions.

Many thanks from Peter Knudsen
