how to get status and category value based on zone name in idea object salesforce
Requirement I have vf page. there I have three picklist
But I am not getting filtered value when I am selecting A zone name from Zone picklist. It gives us all category and Status values.
But in standard sf page Idea detail page, It do these filtering. I want to do the same.
I have tried getting dependent field value using MetaData Api as well. but no luck because Zone(CommunityId-Apiname) is not dependent field of Status and Category field in Idea object, but behave in that manner(Magically).
ZoneId is label name and api name is CommunityId, is reference field in Idea obejct
Status and Category are picklist type of field and can have different-2 value depends upon Zone selection.
ZoneId is not controller field but behave like controller field for Status and Category field. This all are standard field(Category, Status, CommunityId(label as Zone)) and standard object(Idea)
In the end I would say,Zone is behaving as RecordType.
