    • title: The localized title of the link.
    • href: The system path to link to.
    • localized_options: An array of options to pass to l().
  • #active: Whether the link should be marked as 'active'.

Parameters

$data: An associative array containing:

  • actions: An associative array containing:

    • count: The amount of actions determined by the menu system, which can be ignored.
    • output: A list of of actions, each one being an associative array as described above.
  • tabs: An indexed array (list) of tab levels (up to 2 levels), each containing an associative array:

    • count: The amount of tabs determined by the menu system. This value does not need to be altered if there is more than one tab.
