Take for example I have two CPTs – Developments and Properties. Developments will be collated of properties. So whens setting up a property I will have a post object field to select a development to associate it to.
Under the Property CPT list of posts with the filters at the top, I’d like to add a custom one which will pull through the post object field of developments so I can filter the properties by development.
I’ve had a search round the web without any luck for something like this – is it achievable?
