Hi, I'd been looking for the answer to this for a while as well. I found that you can add a single line of code to the commented out function in the function.php file that is supplied for the child theme:
'depth' => '1',
The code will then look like this:
function childtheme_menu_args($args) {
$args = array(
//The depth argument disables the dropdowns and only passes the top level.
'depth' => '1',
'show_home' => 'Home',
'sort_column' => 'menu_order',
'menu_class' => 'menu',
'echo' => true
);
return $args;
}
add_filter('wp_page_menu_args','childtheme_menu_args');
If you don't actually want to include the home link, you can just delete the line
'show_home' => 'Home',
The depth set at 1 will only show the top level navigation.
Hope that helps...
