Network wide menu & Mega menu

Hello Devin!

I do this (it works):

add_filter('wp_nav_menu', 'wp_nav_menu_global');

function wp_nav_menu_global()
{
 	if ( !is_main_site() )
	{
		remove_filter( 'wp_nav_menu','wp_nav_menu_global');
		switch_to_blog(1);

	$args = array(
			'theme_location'	=> $avia_theme_location,
			'menu_id' 			=> $avia_menu_class,
			'container_class'	=> $avia_menu_class,
			'fallback_cb' 		=> 'avia_fallback_menu',
			'walker' 			=> new avia_responsive_mega_menu()
			);

		wp_nav_menu($args);
		restore_current_blog();
	}
		
}
