Nesting Information

Hi there!

I want to nest information. For a better understanding please look at
that picture.

There is the workspace, which contain layers. in theese layers are
containers which are filled with different entries.

What would be the best way to solve this in rails?

I thought about using a pattern-template for the workspace, then one for
layers, … and so on. But how to program this practically? How to get an
extern template (the _template) ones intogether?

Thanks for you help!
