Populating SelectFilter with relation.

I have a belongsTo relation between my StudentProfile and my User model. From the StudentProfile resource I'm trying to populate a SelectFilter with available courseClasses. The courseClass has a belongsTo with the User. My selectfilter is setup like this:

                SelectFilter::make('classname')
                    ->relationship('user', 'class_id')
                    ->label('Klas'),

                SelectFilter::make('classname')
                    ->relationship('user', 'class_id')
                    ->label('Klas'),

This however, populates the select filter with all available class id's from the student resource. This way I have duplicates and also selecting one ID just filters one user. What would be the correct approach?

What are you trying to show in the filter exactly? All classes or just the classes for this specific student?

I would like to select one class in my filter and get all students in it. In my current setup, I have e.g. 10 students in class "a" and 5 students in class "b". My filter is populated with 10 x 'a' and 5 x 'b'. Each filter selection just shows one student as result.

I see, makes sense. Can you share a bit more information on how the relationships are setup in your models?
