I want to show an arrow (add text) ">>" behind all the navigation items that have subitems/subpages. Is there a solution with add_filter or do i have to build the menu by myself?
Thanks for help!
Not exactly what you ask.. This adds a class="dropdown"
to your menu's
// add a class 'dropdown' to menu items which have a sub menu
add_filter('nav_menu_css_class', 'check_for_submenu', 10, 2);
function check_for_submenu($classes, $item)
{
global $wpdb;
$has_children = $wpdb->get_var("SELECT COUNT(meta_id) FROM wp_postmeta WHERE meta_key='_menu_item_menu_item_parent' AND meta_value='" . $item->ID . "'");
if ($has_children > 0)
array_push($classes, 'dropdown'); // add the class dropdown to the current list
return $classes;
}
