  1. Usually this is done by hand editing the menu but it can be accomplished using WordPress custom fields. Simply add a custom field to the pages in question named “subtitle” with a value of “whatever you want your descriptive subtitle text to be”. Then make sure you have the following code snippet (adapted from the clearskys.net blog ) in the functions file of your WordPress Child Theme—as long as the parent theme is using wp_page_menu. If you’re simply editing a WordPress theme directly, cut the code from the childtheme_page_menu function and use it to replace your existing menu in header.php.
