I was wondering if there is a way to create the following in the user template.

I want only a specific group of fields to show up under Department.

Under creation Rule I would like to be able to select The office, when the office is selected I want only the Departments pertaining to that office to show up.

Something like this

-------School A (Office)

            ---School A Department 1

            ---School A Department 2

            ---School A Department 3

            ---School A Department 4

Thank you
