3.0 menus

Does anybody know how to make a horizontal menu with a sub horizontal menu with the new menu functions?

Like this: http://www.dn.se/sport/

Current code in header.php shows the same pages in both menus:

< ?php wp_nav_menu( array('menu' => 'Huvudmeny', 'container_id' => 'navcontainer', 'menu_id' => 'navlist', 'dept' => '1', 'theme_location' => 'primary' )); ? >

< ?php wp_nav_menu( array('sub' => 'Undermeny1', 'container_id' => 'subcontainer', 'menu_id' => 'sublist', 'dept' => '1' )); ? >

Both menus are registered and we do not use widgets.
