More than one header style

It is, go to Avia builder, and “content elements” and choose “fullwidth sub menu” there you can either build an simple menu, or use an exicisting menu you have created in the menu section of WP.

well there was a snippet ( a bit bigger than the others) to have for each page/post the opportunity to choose if header is top, left or right.
for that snippet you have to use by default first the top header and than switch on the page.

add_filter('avf_builder_elements', 'register_meta_elements', 10, 1);
