title: How to add custom post type to nav_menu in Wordpress?
body: <p>I have a question.</p>
  
  <p>I use the new <code>custom menus</code> of Wordpress 3.0. And I'm wondering how can I add custom post types to the menu. For now, I can just add <code>Pages</code> and <code>Categories</code>.</p>
  
  <p>Thanks</p>
