I am trying to create a lesson where the layout is like this:

---Module 1
----Lesson 1
----Lesson 2

---Module 2
----Lesson 1
----Lesson 2

So different lessons can be displayed in different modules, but is this possible with the software? I can't seem to be able to do it.

Thanks :)

Its ok I think I discovered folders to do this, its taking me a while to figure this software out.
