Ability to Select Header Position on Page – Overwrite Theme Settings

Hey Mike!

Add this to your child theme functions.php:

add_filter('avf_builder_elements', 'register_meta_elements', 10, 1);
function register_meta_elements($avf_builder_elements) {
	$avf_builder_elements[] = array(
		"slug"  => "layout",
		"name"  => __("Header Position",'avia_framework'),
		"id"    => "header_position",
		"desc"  => "Select the position of the header",
		"type"  => "select",
		"std"   => "",
		"class" => "avia-style",
		"subtype" => array( 
		                    __("Default",'avia_framework') => '',
		                    __('Top Header','avia_framework') =>'header_top',
		                    __('Sidebar Header (Left)','avia_framework') =>'header_left header_sidebar',
		                    __('Sidebar Header (Right)','avia_framework') =>'header_right header_sidebar',

That will add a new option in each Page where you can set the Header Position per Page.

Few things:
– There’s an issue with the search icon and sidebar headers so i’d suggest not activating it.
– Have the Top Header setting as default (in Theme Options), that way the header transparency settings (in each Page) will be available.
