Drupal 6 – output your primary links as a Site Map
This took me a while to find: In Drupal 6, I wanted to output the main Primary Links menu item, expanded, as a site map:
Simply add the following to a node (with PHP parsing ON!)
<?php $tree = menu_tree_all_data($menu_name = ‘primary-links’, $item = NULL); print menu_tree_output($tree); ?>
