Restrict the Student year dropdown on a giving form

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

For a school-owned editable Student affiliation, open School-Level Settings → Affiliations, choose Include Dropdown and type Years, set the desired Start Year and End Year, remove unwanted custom options, save and preview. The start year appears first, so it also controls ascending versus descending order. This changes the shared affiliation definition used by other forms/events; it does not rewrite past gift selections.
