tool to handle nested forms using jQuery
Nested forms are forms that handle nested models and attributes in one form; e.g. a project with its tasks or an invoice with its line items.
Cocoon is an unobtrusive nested forms handling, using jQuery. It is form builder-agnostic, so it works with standard Rails, Formtastic, or SimpleForm. It is compatible with rails 3 and rails 4.
