  Filter Options can return a

  where

  query

  https://payloadcms.com/docs/fields/relationship#example
  

  You'll need the return object to discriminate the type for you. One way would be to add a new property with the same name on both collections in your

  relationTo

  so that you can say

  type: { equals: "activity" }

  or

  type: { equals: "community" }

  for example. It would make sense to make this a hidden field with a defaultValue so that it is not in the admin UI at all.

  
  
  

  You may not need a new field to act as the discriminator if you have some existing fields that both collections share that have distinct options which can be queried that can serve this same purpose.

  
  
  

  Alternatively you might simplify your approach by breaking your one relationship field down into two different fields that you conditionally render based on the visitType, each with a relationTo the corresponding collection.

  Thanks @dribbens , that's what I thought. Sadly they don't share any field. I'm going to consider the two different fields, but I wold need to change some parts in the front, to be able to read the url from the relationships (activity/community), but maybe it's not that dificult.
