Second level hierarchy/drill down

Is there a way to do the scaffolding for a second layer of drill down?

For example:

I have stores

First layer is book stores

Want to add a second layer for book store notes, not store notes, but book store notes

Hi @Chad,

There is no built-in way to scaffold a three level hierarchy. You can probably use the existing code to add the third level yourself.

that's what I thought, just wanted to make sure, thank you.

I have a start to it based on existing code like you suggest.
