A profiles list is a field that allows the user to select from a list of user profiles currently visible within the directory. This field takes the form of a drop down control, and only one profile can be selected.
When configuring a profiles list, you can specify a dependency on one or more prior fields on the form. A dependency on a prior field controls whether or not the profiles list appears on the form. The dependency can be based on any value entered in the prior field or on a precise value.
