How can I close registration on a course that has reached its maximum registrants?

Hello,

I recently asked this question and was directed to get the submission widget. I tried that out however, it closes the entire form after a certain number of registrants, which is not exactly what I meant. I have a list of classes for students to chose from. When any class chosen reaches the maximum amount of students allowed in that course (14), I want it to stop the ability for someone to select the course as a choice. Make it not clickable or state class full...something to that effect. Am I using the wrong for for that type of registration? 

Please help
