## 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.

Glad it helped! I just discovered this combination today as I was looking to build this exact functionality for a client and had to share!
