Regions in CompositeView

[Jason Lock]

I have a accordion style menu thats created from a CollectionView and CompositeView (http://davidsulc.github.com/backbone.marionette-nested-views/). I need the expanded content of the accordion to be dynamic and have its own controller and model. I was thinking of nesting a region as the accordions content area so I can use open/close from within the expanded content controller. Is this a good idea or is there another approach I should try. 

Thanks for the help!

I don't think its a terrible idea.

I wonder if its possible to specify a LayoutView as the collection's itemView since:

A Layout is a hybrid of an ItemView and a collection of Region objects. They are ideal for rendering application layouts with multiple sub-regions managed by specified region managers.

If not I guess that's why they made region managers available outside of layouts :)
