The standard 'secondary links' functionality - selecting the same multi-tier menu as your primary links - only caters for one submenu layer to be displayed. What if you want a menu that behaves as the navigation block, expanding to submenus when appropriate?
This code snippet can be placed in a block, and will do just that.
<?php
$primary_menu_id = variable_get('menu_primary_menu', 0);
if (menu_in_active_trail($primary_menu_id)){
// get the menu items that lead to the current menu item
$active_trail =_menu_get_active_trail();
// get the menu id of the active top-level link
$mid = $active_trail[1];
$menu_item = menu_get_item($mid);
print '<h2>'.$menu_item['title'].':</h2>';
$menu_tree = menu_tree($mid);
print '<ul class="menu">'.$menu_tree.'</ul>';
}
?>_menu_get_active_trail() code developed with help from this forum thread.
