Im using the Sonata Admin bundle for the back office of an ecommerce project.
You can create brands, add collections, items, sub items and price. All of these elements are entities.
It seems like, with sonata admin (using the 2.3 branch) I can't add more than 2 levels of nested collections (https://github.com/sonata-project/SonataAdminBundle/pull/1971)
How is the best way to work around that lacking feature and still be sonata friendly?
