Works best if you set this up before adding any pages.

If you try to use this plugin on an existing site that has a menu, it will appear to not work correctly at times, but after reading the description of this plugin a few times, it will start to make sense. Child pages will only populate for newly created pages. Child pages will also only populate if the immediate parent ( the one right above it) is already in the menu. So in the case that you have level 1 items and level 2 items created already, you will need to manually add level 1 and level 2 items for level 3 items to populate automatically. One thing that this plugin requires you to do is to check the ‘Automatically add new top-level pages to this menu’ option in the menu settings at the bottom. Given that this will add more pages to the top level, you may have a menu that only fits 6 items. In that case, you have to find a way to either include on the ones you want, delete them every time a new top level item is added, or create a separate menu. In the case that you have a dropdown menu you can just remove the ones as they get added, and if you don’t have a dropdown menu, then it’s best to create a separate menu.

I am rating this a 4 out of 5 because the plugin is not explained well and some things are not made immediately clear to users making it seem to ‘not work’ at times, even though it does do what it says.
