Menu will not move under the logo

Well, you can always move elements using position absolute or relative, it depends, but then you have to fine tune this positioning for all viewports.
An alternative, I used is to move it with php:

And then style it the way you want with .navbar-wrapper-outside and .navbar-outside

Hope this helps.

that is perfect – thank you! ??
