What about...a checkbox taxonomy! Whoo hoo! What an awesome idea!

I used CustomPress to create the Custom Post type "Courses."

Now I'm working on Taxonomies.

I want users to simply be able to check a box to indicate whether or not their course is Online.

So it would look like [checkbox] Are you holding your course online?

Then, on the site, when you hover over "Courses" in the Nav Menu, I want to see a child category that reads "Online Courses" which of course would show all of those courses that had been checked as online.

How do I do this?

Followup question:

Is there a better way to have Courses as a menu item instead of pasting in a link to the Course Archive page? I selected True for "Show In Nav Menus" but this just allows me to check boxes to say which courses I want in the menu. Which isn't exactly what I'm looking for.

Thank you all you awesome people!
