Do you want to remove unnecessary classes being added while using custom menus? Well, here’s a snippet to remove them, while maintaining the only useful class, ‘current-menu-item’.
Instructions:
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
<?php
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($var) {
return is_array($var) ? array_intersect($var, array('current-menu-item')) : '';
}
?>
