Here’s the scenaro:
In an app, users can create Private or Public posts.
Within each post, users can create Private or Public subitems.
However, when creating the subitem, the privacy settings should not only INHERIT the parent category’s privacy settings but also RESTRICT the user from selecting certain privacy settings based on the parent topic.
In the video below, I explain how a Public post will allow users to create public or private subitems, and a Private post will allow users to only create a subitem that is “Private”.
TL:DR: If-Then-Else column > split column > relation column to the Privacy choices and using the relation column as the source for the choice component.
