Update: check Tertiary links / 2: tree workaround before this. That’s a wiser solution in many cases.
Tested on:
- 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.
<div id="secondary"> <?php
#display tertiary links menu on 2nd level
$tertiary_links=menu_primary_links(3, variable_get('menu_primary_menu', 0) );
#display secondary links menu on 1st level
if($my_secondary_links):?>
<?php
print theme('links', $my_secondary_links, array('class' => 'links tertiary-links'));
?>
elseif ($secondary_links): ?>
<?php
print theme('links', $secondary_links);
?>
</div> <!-- /#secondary -->
<?php endif; ?>
