Meta box group inside meta box group

Hi there, I'd like to make a restaurant menu with metabox group.

This the first big group clone with one single category title
Title Category - ie. Salads

And this items clone also.
Title Salad - ie. Ceaser Salad
Description Salad - ie. Lettuce, rockets ...
Price - 9.99

Title Salad 2 - ie. Tomato Salad
Description Salad - ie. Lettuce, rockets ...
Price - 8.99
