Which create/update field should we use for a n - to - n relationship?

[realtebo]

We have a school, so there is a n-to-n relationship between users and institute classes ("3H, 4I, 1C, ... etc..");

When editing a teacher I'd like a fast way for user to activate/deactivate the association with classes.

Is there a field handling many-to-many relationship in a list-like style ? (list of radios, I think)

Actually I'm using the super magic select2 served by type('relationship'). But I think a list of radios will be simpler to use

    CRUD::field('teacher_classes')
        ->label("classes")
        ->type('relationship')
        ->attribute('name')
        ->placeholder("Select all teacher's classes")
    ;

Nope.
