How can I create help articles and categories with CMS collections?

On most sites when you go to their help page you can see a number of categories, such as “Account,” “Payments,” etc. When you click on those categories you are shown different questions that relate to the help you need.

When using CMS collections is there a way to have folders inside of each collection so that I can create help articles the way I’ve described above? For example, can I have a collection titled “Help Articles” then inside that collection have a “Payments” folder then inside that folder have different questions? If not, is there another way I can do this?
