Navigation Bar Confusion

Hi there,
I try to add a navigation bar on the top. What do I take for that? I suppose a Bric, like Nav Bar, yes? Problem, I cannot find the data source. And the Hamburger thingy doesn’t work either.

This seems to be outdated:

Any help, or ideas?

Hmmm, I think I found the element to do it (Nav Toggle), and to edit the menu (hamburger) symbol.

But there is no Hamburger symbol or any other symbol visible, even in the preview

My first thoughts would be that you’ may be looking at one of the breakpoints where the hamburger is invisible - either large or medium screen sizes.
I think by default, the hamburger is only set to visible on small and extra small.
