Flag unexisting entities #13
Description
One or more posts stored somewhere might no longer be available.
Ideally you would be informed about this case.
An idea is to add custom styles via a flag property for each of the posts that no longer exists.
See how's possible to perform this at once when the posts options list is retrieved rather than making an additional request to the server.
Do not forget the REST Response is merged with the hardcoded options.
