I add the code and below is what I have in my header.php file. The problem is the drop down in the navigation for the category (sub-categories) are not showing up they are for the pages. The drop down does appear in the sub-nav menu. I have tried a couple of different things and it does not appear.
<?php wp_list_pages('title_li=&depth=4&sort_column=menu_ order'); ?>
<?php wp_list_categories('sorderby=name&depth=4&include= 7&&title_li='); ?>[/list] </div>
