I think this is a theme issue. Have you tried switching to the default theme to rule out any theme-specific problems?
Thanks for the reply. It works fine by setting a page with a parent. This is my menu CSS:
[CSS moderated. A link to your site is all that is needed.]
Any ideas? Or do I just have to add them to the menu?
[No bumping. These are volunteer-staffed free forums – not commercial online support chat! If it’s that urgent, consider hiring someone.]
Also if I do is there a limit on how many links you can have in your menu?
In theory, no – although, in practice, the size of your menu may be limited by your server’s configuration.
Ok, I may just leave it then. Not sure its worth a lot dev time to have a menu highlighted. Just thought there maybe some easy way within WordPress or PHP. Thanks for your help.
