function i18n_menu_parent_options in Internationalization 7

Return a list of menu items that are valid possible parents for the given menu item.

@todo This has to be turned into a #process form element callback. The 'menu_override_parent_selector' variable is entirely superfluous.

Parameters

$menus: An array of menu names and titles, such as from menu_get_menus().

$item: The menu item or the node type for which to generate a list of parents. If $item['mlid'] == 0 then the complete tree is returned.

Return value

An array of menu link titles keyed on the a string containing the menu name and mlid. The list excludes the given item and its children.
