User Story

As a user, I want to select content based on its relationship to other items, so that I can establish meaningful connections between content pieces without confusion.

Acceptance Criteria

1. Button Behavior Based on Relationship Type

• For 1-to-1 relationships:

  • The "Relate" button should be disabled if the user has not selected exactly one content item.
  • Once a single content item is selected, the button should become enabled.

• For 1-to-n or n-to-n relationships:

  • The "Relate" button should always be enabled, allowing multiple selections.
  • Ensure proper validation and handling for multiple content selections.
