Matrix Field: How to ensure that all input answers are unique per submissionAsked by MarkSir on January 26, 2016 at 03:42 AM
Students have to rank 76 subject groups and each subject group can only be chosen once.
In each field, they have to use a code. They need to type in instead of using a pull down menu as with 76 choices, the pull down menu will become to long.
Unfortunately, we do not provide unique value validation option for a Matrix field type. We would like to recommend you to stick with the Orderable List widget.
