In many cases, users only want to display certain categories in their navigation menu at the top of the page. There are limited spots, that can only be filled by top categories, but if you use the default wp_list_categories code, it will show all categories. This is why this hack below comes in very handy when you want to create a navigation menu and only display certain categories.

[code lang=”html”]
<ul class=”navmenubar”style=”float:left; width:730px;”>
<?php wp_list_categories(‘orderby=name&include=7,9,19,16,1,5,17,23’); ?>

</ul>
[/code]
