function _megamenu_get_menu_tree in Megamenu 7

Same name and namespace in other branches

1. 6.2 megamenu.utilities.inc \_megamenu_get_menu_tree()
2. 6 megamenu.utilities.inc \_megamenu_get_menu_tree()

Retrieve a menu and pre-style before theming.

This function currently removes all "hidden" items, which could be handled in the single iteration of the theme function. But, I forsee a need for other prep work that might be simmplfied with this second function

Will be used in the future to add/alter attributes prior to theming

Parameters

$menuname: The name of the menu to extract

Return value

The pre-styled menu tree

1 call to _megamenu_get_menu_tree()
