Navigation menus in WordPress are not performing very well in case of lots of submenus, sections, multilevel items or the well-known mega-menus. Here’s a function that allows you to cache the output of your navigation menu.


  1. WordPress Lighthouse plugin
  2. A modern WordPress theme using wp_nav_menu() function


In order for this tutorial to work, activate the Lighthouse plugin and replace wp_nav_menu() with lhf_nav_menu() in your header.php and footer.php templates. All the other parameters stay the same. See sample usage below.

if(function_exists('lhf_nav_menu')) {
    lhf_nav_menu(array('theme_location' => 'primary', 'menu_class' => '', 'container' => 'div', 'container_class' => ''));
} else {
    wp_nav_menu(array('theme_location' => 'primary', 'menu_class' => '', 'container' => 'div', 'container_class' => ''));

Enjoy your faster menu!
