How do I display a list of items and sub items from two different tables

[eluser]Dan Bowling[/eluser]
I'm new to MVC, so I'm a little confused on this simple task.

I'm basically trying to show a series of items (in one table) that each have another set of items belonging to them (in another table, related through a foreign key).

I want my output like this:

Section
-item
-item
Section
-item
Section
-item

How do I set up this sort of MVC with CI?
