I am using the Omega HTML5 base theme and am attempting to add a '/' delimiter between main_menu items on my site.

I have searched high and low and the closest I've come is the following:

function MYTHEME_menu_link(array $variables) {
$delimiter = '';
  // Only add delimiter to the main menu
  if (strpos($variables['element']['#theme'], 'main_menu') !== FALSE ) {
    // Only add delimiter if item is not the last one
    if (!in_array('last', $variables['element']['#attributes']['class'])) {
      $delimiter = '<span class="delimiter">/</span>';
  $element = $variables['element'];
  $sub_menu = '';

  if ($element['#below']) {
    $sub_menu = drupal_render($element['#below']);
  $output = l($element['#title'], $element['#href'], $element['#localized_options']);
  // Add delimiter just before the closing </li> tag
  return '<li' . drupal_attributes($element['#attributes']) . '>' . $output . $sub_menu . $delimiter. "</li>\n";

This actually works on any another template (just not OMEGA). Irrespective does anyone have an approach to adding this forward slash on main-menu items?

I would suggest a purely CSS approach to this. There is really no need to go through the trouble of adding a function to your theme for this change.

The following CSS code would get you (at least close to) the results you desire:

  ul.main-menu li:after {
    content: "/";
  ul.main-menu li.last:after {

The :after pseudo-class's support includes all browsers except IE 7 & below and Firefox 3.0 and lower.

  • Completely forgot about using :after as an approach - (have been looking at this for way too long...). Thanks for putting me straight on this!

  • oh yeah, and then don't forget to unset that style for the last li! Edited my answer to show that :)

  • Actually it'd be ul.main-menu li.last-child:after {} (or first-child if you wish to change the beginning)

For those using Sass, I have written a mixin for this purpose:

@mixin addSeparator($element, $separator, $padding) {
    #{$element+'+'+$element}:before {
        content: $separator;
        padding: 0 $padding;


@include addSeparator('li', '|', 1em);

Which will give you this:

li+li:before {
  content: "|";
  padding: 0 1em;
