This module adds additional domain based settings to control a number of field settings, including field display and editing access, required flag, label and help overrides.
The main functionality is to provide an interface to the Drupal 7 hook hook_field_access() so that you can hide unwanted fields based on the active domain for editing and / or display.
It can not be used to grant access to fields that are already restricted.
You can use this module to specify that a field is required on a particular domain. If the entity field is defined as required, you can not change this with this module.
See the [#1414994] for developmental plans.
You must have the Domain Access module enabled to use this module. This has only been tested against the latest Domain Access module, version, 7.x-3.3.
