I created different bb-child-themes with all different template presets. If I switch to such a child theme I always loos the menu in the header and I need to go to: Design --> Menu --> set the menu to the header position. Is there a way i can set the menu in the header from default (within the child themes function.php)?
I did test out a few things regarding this and you can set the menu by overriding the specific header layout you have(nav-right, nav-bottom, or nav-centered). You can just include that in your child theme under the same folder /includes/ then edit this part, adding ‘menu’ to the array.
