Question

Been searching for a while on this subject without any success. All I can find are solutions which involve using the Walker property of the wp_nav_menu, which I don’t think is the right approach. I want to create a menu with the following structure:

• Link that is a category

  • X numbers of submenu items which are posts belonging to the parent
    category

And so on…

Do I need to manually run a loop for each menu item to retrieve the posts?

Answer 1

Try this in your functions.php:

add_filter('wp_nav_menu_items', 'add_productions', 10, 2);
function add_productions($items, $args) {
  $cat = '28'; // define category
  $productions = array();
  $productions = get_posts("cat=$cat");
  if ($productions[0] != '') {
      $items .= '<li><a href="#">Productions</a><ul class="sub-menu">';
      foreach ( $productions as $production ) {
        $permalink = get_permalink( $production->ID );
        $items .= '<li><a href="'.$permalink.'">'.$production->post_title.'</a></li>';
      }
      $items .= '</ul>';
  }
  return $items;
}
