This has nothing to do with JSF. You need to think about how you're doing you basic GUI layout.
Certainly I'd expect that if the list selected students, the student's name would be the label, not the college. If you want to select multiple students - whether from one college or many, a select ONE control isn't what you need, you need some sort of select MANY control.

i just told you the example, our requirement is:
two itemvalue 'C' and 'N' come under same group i.e item label 'Consultant'
when C or N is selected, it sholud display consultant from dropdown automatically.
