Is it possible to make an attribute mandatory once another attribute is selected/changed? Here's an example of what we're trying to accomplish:
For one of our request forms, the user selects a checkbox (boolean attribute) if Email Access is required.
We then have a reference list dropdown for the user to select the type of email access (Email Type).
We want it so when the checkbox is selected, the Email Type attribute becomes mandatory.
A bonus would be to have them do the same: if one or the other is selected, to make the other mandatory.
