I have just tried to add a second level menu item to my site that uses restarter plus and the menu item does not appear. I briefly reverted back to a default WP theme and it shows as expected.
Does restarter (plus) support multi level menu's?
If not, is it likely to be something that I can add to my child theme? I've done a bit of CSS and menu bits in the past, just not with wordpress.
Even if initially I just get a poorly styled menu item? At the moment, the page source code does not even show that the menu item exists. I guess that somewhere something is telling wordpress not to show menu items below a certain level otherwise I would expect to see the menu item in the page source code.
