Is it possible to print content of all menu items, when displaying menu (or branch of menu as in question about displaying menu branches) ?
Once I click on About Us
I wish for new page to display content of all it’s children links.
So basically I am looking for a way to get IDs of those posts/pages and use them inside my WP Query.

I am lazy to write supporting logic from scratch so I am reusing functions from linked answer on branches:
/**
* Retrieve IDs of posts in branch of menu.
*
* @param mixed $menu
* @param string $branch_title
*
* @link http://wordpress.stackexchange.com/questions/2802/display-a-portion-branch-of-the-menu-tree-using-wp-nav-menu
*
* @return array
*/
function get_post_ids_from_menu_branch( $menu, $branch_title ) {
$menu_object = wp_get_nav_menu_object( $menu );
$menu_items = wp_get_nav_menu_items( $menu_object->term_id );
$items = submenu_limit( $menu_items, (object) array( 'submenu' => $branch_title ) );
$items = wp_list_filter( $items, array( 'object' => 'post' ) );
$ids = wp_list_pluck( $items, 'object_id' );
return $ids;
}
// example
var_dump( get_post_ids_from_menu_branch( 'Test menu', 'Level 1' ) );
