I've come across some instances where I'd like to conditionally display the relationship meta box depending on a custom field value selected in a custom field meta box. Adding conditional logic to relationships would definitely help improve user experience.
Each meta box relationship has the ID with the following format relatioshipID_relationships_from or relatioshipID_relationships_to. You can use conditional logic outside of meta box with that ID to show/hide the relationship meta box. Please read more on the documentation https://docs.metabox.io/extensions/meta-box-conditional-logic/#using-outside-meta-boxes
.
