Aaaaand… the formatting deleted my extra spaces. Sigh.
Ok, it’ll look like this:
Hands
__Fingers
__Thumbs
Ok, For other people wondering, I stumbled onto the solution. It’s a simple one, you’ll be happy to know. 🙂 While in your “Menus” section, simply drag the category you would like to put in the drop down menu to the right. It will now be included inside a dropdown menu within whatever category you have above it. For example:
Hands
Fingers
Thumbs
In this example, on your main page, when you hover over “hands” the dropdown menu will appear with the “Fingers” and “Thumbs” options.
Don’t forget to hit “save”.
Can you tell us what you did? I’m having the same issue. Also can’t figure out how to add an archives page (though I suppose that’s sort of another issue.)
