Sometimes you need to customize the default wordpress menu system to add your own set of css classes. WordPress provides a couple of filters to do that.
I use these snippets to add custom classes to list items and menu links in wordpress. Paste these in your functions.php file or your plugin file to make this work.
/* Add custom classes to list item "li" */
function _namespace_menu_item_class( $classes, $item ) {
$classes[] = "nav-item"; // you can add multiple classes here
return $classes;
}
add_filter( 'nav_menu_css_class' , '_namespace_menu_item_class' , 10, 2 );
function _namespace_menu_item_class( $classes, $item ) {
$classes[] = "nav-item";
$classes[] = "another-class";
$classes[] = "more-custom-class";
return $classes;
}
Adding custom class to the menu link is a bit tricky as there is no hook or filter to work with the “a” element directly. So we will take a roundabout way and use a string replace function
/* Add custom class to link in menu */
function _namespace_modify_menuclass($ulclass) {
return preg_replace('/<a /', '<a class="nav-link"', $ulclass);
}
add_filter('wp_nav_menu', '_namespace_modify_menuclass');
What we are doing here is adding a filter function to wp_nav_menu which returns the whole menu block and then replacing the “a” element with a desired class.
