In the area Settings for content type-specific uniqueness you will find a drop-down menu that gives you the three possible settings for uniqueness.
- Switch off uniqueness: There is no check for this content type. Multiple assignment of a title is possible.
- Enable weak uniqueness: Checks are performed for this content type. However, multiple assignment of a title is possible. When editing or creating an object, only the multiple assignment is pointed out.
- Enable uniqueness: A check is performed for this content type. Multiple assignment of a title is not possible.
After selecting, press Save Settings. If you enable uniqueness and there are objects of this content type with the same title in your system, an error message will appear. In this case, rename or delete these objects with the same title.
