Add Search to Secondary Menu Virtue

If using a child theme, you can add a search bar to your secondary menu by adding this function to your functions.php file. If not, you can also utilize the code-snippets plugin.

add_filter('wp_nav_menu_items', 'custom_add_search_form_to_second_menu', 10, 2);
function custom_add_search_form_to_second_menu($items, $args) {

	if( !($args->theme_location == 'secondary_navigation') )
		return $items;

	ob_start();
	?>
	<li class="menu-search-icon-kt">
		<a class="kt-menu-search-btn collapsed" title="<?php echo __('Search', 'virtue');?>" data-toggle="collapse" data-target="#kad-menu-search-popup">
			<?php echo __('Search', 'virtue');?>
		</a>
		<div id="kad-menu-search-popup" class="search-container container collapse">
			<div class="kt-search-container">
			<?php
				get_search_form();
			?>
			</div>
		</div>
	</li>
	<?php  $output  = ob_get_contents();
	ob_end_clean();

	return $items . $output;
}

If you wish to instead use a WooCommerce search, change the

get_search_form();

to

get_product_search_form();
