Have a few menus on your site & looking for a quick way to add or change the menu classes and attributes? Use the theme_menu_tree__[menu_name] override in your theme’s template.php file to change Drupal 7 menu list class and attributes:

// template.php

/**
 * Override theme_menu_tree().
 */
function theme_menu_tree($variables) {
  return '
' . $variables['tree'] . '
';
}

/**
 * Override theme_menu_tree__[menu_name]().
 */
function theme_menu_tree__main_menu($variables) {
  return '
' . $variables['tree'] . '
';
}

The code above will allow you to easily change all menu ul classes and other attributes or just the main menu’s ul classes and attributes.

Looking for a module to change Drupal 7 menu list class & attributes?

Unfortunately, I haven’t been able to find one that handles the individual menu ul instances cleanly, but the Menu Attributes module is a start. It gives users the ability to set the following attributes for each menu item — this does not help with setting the ul classes & attributes:

• id
• name
• target
• rel
• class
• style
• accesskey
