You'll find two views: MANAGER and Student.
The MANAGER can add / delete / edit any record; the Student can only read.
The recordings are added into MANAGER after the students are enrolled.

In August 2018, I asked the following question.... is it similar to your situation?

===================================================

Let's say I have 100 entries in a Dataform that has a field (named MYTYPE) that I want to use as a "dynamic filter". For example:

1. I want to display a dropdown consisting of the UNIQUE values of the field named MYTYPE.
   
2. When the user chooses one of the dropdown options, I want a filter to be applied that shows only the entries where the field MYTYPE contains the value selected by the user. 

By the way, I don't know the possible values of the field MYTYPE, because the user enters the values themselves.

Can this be done?.... 

===================================================

I never got an answer, but I am hoping you and I might be able to combine our efforts for a solution.
