    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.

    If you need any further assistance, please let us know.
