Andykev, thanks for your response.
Unfortunately, this isn’t what I want. This causes the menu item to be permanently highlighted.
I only want the menu item highlighted if the page or one of its child pages is active.
So, for example, ‘About’ is one of seven menu items. The About page is parent to six pages; one of the six pages is ‘Our Company Values’. The six pages are not in a sub-menu.
If I’m on the Our Company Values page, I want the About menu item to be highlighted.
Is this possible and, if so, how do I do it?
