Allow several alumni and parent class years on a giving form

In GiveCampus giving forms, available controls depend on your permissions and the interface used by your institution.

Enable Allow Multiple for each relevant dropdown affiliation and set its Selection Limit to the intended maximum, then preview alumni and parent entries. Choosing multiple affiliation categories is separate from choosing multiple years within one category. These are shared affiliation settings, so an authorized administrator/support should review effects on other forms before changing them.
