Question

I’m trying to figure out how to add a span tag to a certain menu link in a custom menu. I only need it on one link within the custom menu links. Guessing a preprocess function and tried theme_menu_item_link() with no luck, didn’t appear it was getting called at all.

Found the answer! Needed to use theme_menu_link():

function theme_menu_link(array $variables) {
    $element = $variables['element'];
    $sub_menu = '';

    if ($element['#below']) {
        $sub_menu = drupal_render($element['#below']);
    }

    $output = l($element['#title'], $element['#href'], $element['#localized_options']);
    return '<li' . drupal_attributes($element['#attributes']) . '>' . $output . $sub_menu . "</li>\n";
}

There I can find the item I’m looking for and adjust it accordingly.
