function simplemenu_tree_all_data in SimpleMenu 7

Same name and namespace in other branches

1. 6.2 simplemenu.module \simplemenu_tree_all_data()
2. 6 simplemenu.module \simplemenu_tree_all_data()

Modified menu_tree_all_data(), providing the complete menu tree below $root_menu (which can be *any* menu item, not just the root of a custom menu).

@todo we don't actually need $menu_name, $mlid would be sufficient

Parameters

$root_menu: root menu item of the tree to return as "menu_name:mlid" (mlid = menu link id)

File

./simplemenu.module, line 407

Creates a simplemenu.
