Single level menu block for Drupal

Submitted by zany on Wed, 2008-12-10 15:18

Drupal’s menu system is really flexible and the menu blocks are versatile. Also there are a couple of 3rd party modules to display menus in all kinds of different ways.

There is a module to display a single level menu. But it will only display one menu — I needed two (main and sub).

So here is a quick PHP snippet to display a single level menu from Drupal:

Level 1 links only (no tree)

  1.   $level = 0; /* zero-based */
  2.   $lvl_menu = menu_navigation_links(variable_get('menu_primary_links_source', 'primary-links'), $level);
  3.   if ($msm == variable_get('menu_primary_menu', 0)) {
  4.     return theme('links', $lvl_menu, array('class' => 'menu') );
  5.   }

If you don’t want the block to disapear when there is no menu, replace the return with print. I.e.

  1.   $level = 0; /* zero-based */
  2.   $lvl_menu = menu_navigation_links(variable_get('menu_primary_links_source', 'primary-links'), $level);
  3.   if ($msm == variable_get('menu_primary_menu', 0)) {
  4.     print theme('links', $lvl_menu, array('class' => 'menu') );
  5.   }
  6.   print "<br />";

UPDATE: see also the Menu block module.
