How to Remove CSS Classes From Menus, Except the Ones You Want

Are you looking for a way to remove CSS classes from menus except the ones you want? While there’s probably a plugin for this, we have created a quick code snippet that you can use to remove CSS classes from menus except the ones you want in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

add_filter('nav_menu_css_class', 'my_css_attributes_filter', 100, 1);
add_filter('nav_menu_item_id', 'my_css_attributes_filter', 100, 1);
add_filter('page_css_class', 'my_css_attributes_filter', 100, 1);
function my_css_attributes_filter($var) {
 $newnavclasses = is_array($var) ? array_intersect($var, array('current-menu-item', 'current_page_item', 'current-page-ancestor', 'current-page-parent')) : ''; //modify to the classes you want to keep
	 return $newnavclasses;
}
