Output secondary links as a menu tree

21-Nov-2007

Thanks for this posting goes to rapidsynergy for posting the solution in this comment on the Drupal forum.

Problem: You're using $secondary_links to display the children of the active menu item in $primary_links, but $secondary_links has children too and they aren't displaying when their parent becomes active.

Solution: Add the following snippet to your template.php file:

<?php
/**
 * Output $secondary_links as a menu tree.
 */

function secondary_menu_tree() {

  // get the menu items that lead to the current menu item
  $active_trail =_menu_get_active_trail();
  
  // get the menu id of the active top-level link
  $mid = $active_trail[0];
  
  // get the primary menus id
  $pmid = variable_get('menu_primary_menu', 0);
  
  //do they match?           
  if ($active_trail[0] == $pmid) {
    return theme('menu_tree', $active_trail[1]);  //create a tree starting from level 2 
  }

}
?>
