I need to add a "has-children" class to the tag if the current page's or post's menu item in fact has children.

As this "logic" has to work with Pages, Posts, Categories etc. menu items it seems it is not easy to find out.

Thanks in advance!

Edit: I am not sure I explained good enough: I need to add "has-children" not if the current page is a page-child but only if the current page's menu-item is a menu-item-child...

There is a body_class filter, if memory serves. That would be the right one to use.

  • As far as I know that doesn't help with how to find out if a page's menu-item is a parent of other menu-items, or does it?

  • Sorry. I assumed you'd know that you need to query the db using $wpdb to know that. Dec 12, 2010 at 11:04

You could use some jQuery, i'd have thought a couple of lines of script is lighter then having to do lookup queries to figure out which items have children..

<script type="text/javascript">  
jQuery(document).ready( function($) {
    $('#my_menu_id li.current-menu-item').has('ul').addClass('has_children');

Of course making sure to update the selector to match your menu ID(s)/Class(es)...

Reference for jQuery has function. http://api.jquery.com/has/

  • That is probably easier than trying to run the check at the body_class filter, but I think he wanted to add the has_children tag to the body class, not to the menu item. Just a minor change. Dec 12, 2010 at 18:48
