I just placed the navigation setup from Twenty Ten in an site using Kubrick as the base. Works fine, now all four of the static pages are listed in the menu. I'd like to add two more items to the menu: "categories" and "archives", so that the listings can cascade down. How do I add that?
Here's the code that calls up the pages. Since I'm no PHP guru, I don't know how to add it to this:
<?php wp_nav_menu( array( 'container_class' => 'menu-header', 'theme_location' => 'primary' ) ); ?>
