Update: check Tertiary links / 2: tree workaround before this. That’s a wiser solution in many cases.
- Drupal 5.x
- Zen subtheme
If you use primary and secondary links in distinct blocks/area of a page, you can add the ability to browse the third navigation level. Just hack your page.tpl.php.
#display tertiary links menu on 2nd level
$tertiary_links=menu_primary_links(3, variable_get('menu_primary_menu', 0) );
#display secondary links menu on 1st level
print theme('links', $my_secondary_links, array('class' => 'links tertiary-links'));
elseif ($secondary_links): ?>
print theme('links', $secondary_links);
</div> <!-- /#secondary -->
<?php endif; ?>
- Tertiary menu in Drupal A very useful howto (I saw this trick here)
