I've recently created a custom post type in which I want to be able to make it a child of another page. These are the arguments I'm passing along when I create my post type:
$args = array( 'labels' => $labels, 'public' => true, 'publicly_queryable' => true, 'show_ui' => true, 'show_in_menu' => true, 'query_var' => true, 'rewrite' => array("slug" => "seminarier"), 'capability_type' => 'post', 'has_archive' => true, 'hierarchical' => true, 'menu_position' => 5, 'supports' => array('title', 'editor', 'page-attributes') );
With this configuration I can see the attributes panel but no "Select parent" dropdown.
Maybe I've just misunderstood the whole concept of hierarchical custom post types but shouldn't I be able to select a parent for my custom post type somewhere?
If you need more information than I've provided just let me know and I'll try to give you what you need.
