This is a sandbox project, which contains experimental code for developer use only.
Custom Display Fields. Let you use custom fields in any entity, but only for display purposes.
This module helps you creating custom fields to be used in the display of an entity exclusiely.
Everything here is Fields API compatible, with just some minor improvements to hook_field_info() and hook_field_formatter_info() structures
A general purpose display field can be used (named CDF Field) to create all displays you want.
