Make Area Before Mobile Menu

Hi ..

In the widgets menu .. you can add items to the area after the mobile menu.

but I want a way to add items before and not after… for example:
when the search option is activated in Header Builder for mobile , it appears at the top of the mobile menu…

I want to add their exact location Register or login option button…

Maybe in the future a language Switch will be added .. whatever

What concerns me is how to access this place so that I can add items.

Please help.
