Only show top-level links in site navigation

Question

This seems like it should be easy to do, but I've not been able to find or work out a solution.

I'm using the Starkers theme and Wordpress 3.0.4, and my site auto-generates its navigation as per normal. I would like however the navigation to only show the top level pages, i.e. not display links to any pages that are children of other pages.

This is the code I am currently using.

<?php wp_nav_menu( array( 'container' => 'nav', 'fallback_cb' => 'starkers_menu',
'theme_location' => 'primary' ) ); ?>

I would like to hide the child links programmatically, but I am prepared to use CSS if someone can instead advise how to assign specific classes to the child links.

Thanks in advance for any help.

**edit 2**

I've tracked down the actual function I am using, called starkers_menu (below). However adding depth to this, or even removing the other exclusions and just using depth doesn't work either:

function starkers_menu() {
    echo '<nav><ul>';
    wp_list_pages('depth=1&exclude=4,19&title_li=');
    echo '</ul></nav>';
}

Answer 1

Had you tried depth argument (see wp_nav_menu() documentation)?

Also do I understand right that you do not setup menu manually and let theme generate it with custom callback that you have in your code?

Update

Same answer - try depth argument, only this time in wp_list_pages() call in starkers_menu() function. It should work, unless that function is never processed and not available at the time of menu running.

Do you use latest version of theme?.. If not consider updating.
