![function forum_menu() {
...
$items['admin/structure/forum/add/container'] = array(
'title' => 'Add container',
'page callback' => 'forum_form_main',
'page arguments' => array('container'),
'access arguments' => array('administer forums'),
'type' => MENU_LOCAL_ACTION,
'parent' => 'admin/structure/forum',
'file' => 'forum.admin.inc',
);
...
}
