Your navigation bar is typically included in the header.php file which is found in your theme folder. Browse down until you find a css mark whose id is “navigation”. In the aquafluid theme, this looks like this:

< ul id="navigation" >

Below this you have typically code that defines what goes in the navigation bar: for example the link to the home page and to other pages of your website. Simply add before the < /ul > code the following line:

< ? php wp_list_cats('sort_column=name&optioncount=0&hierarchical=0'); ? >

This will automatically add links to all of your categories in your Wordpress navigation bar, sorted by alphabetical order. If you want to show the number of posts by category, you should replace “optioncount=0″ by “optioncount=1″. Also, if you wish to exclude certain categories from your navigation bar, you can add the following after “hierarchical=0″ and before the ” ‘ ” sign: “&exclude=1, 2, 3, 4″. In this example, categories whose ids are 1, 2, 3 and 4 will be excluded. You can identify the numbers attached to your respective categories by choosing “manage –> categories” in the Wordpress admin zone.

A navigation bar that first displays a link to your home, followed by links to your categories but excluding categories 2, 3 and 5, would look like this:

< ul id="navigation" >
< li < ?php if(is_home()){echo 'class="current_page_item"';}? > >< a href="< ?php bloginfo('siteurl'); ? >" title="Home" >Home< /a >< /li >
< li >< ?php wp_list_cats('sort_column=name&optioncount=0&hierarchical=0&exclude=2, 3, 5'); ? >< /li >
< /ul >


Important note: do not copy the code lines above. To prevent the code from executing on this page we have added spaces after the “<" and before the ">“. You would need to delete these blanks to make the code functional.
