Overview:
Expected document fields can be managed as read-only on the document information UI through field dependencies. However, the fields do not appear on the document information UI.
Root Cause:
The controlling field, document type, or lifecycle state dictates the behavior of dependent fields in one of these ways:
- Read Only: The Dependent field is visible and set to read only when the controlling field conditions are met. Otherwise, the field is hidden.
- Visible: The Dependent field is visible and editable when the controlling field conditions are met. Otherwise, the field is hidden.
- Required: The Dependent field is visible, editable, and required when the controlling field conditions are met. Otherwise, the field is hidden.
- Hidden: The Dependent field is not visible when the controlling field conditions are met. Otherwise, the field is visible and editable.
Example: Use the screenshot below. If the country does not equal New Zealand or Australia, the Expiration Date field is not displayed in document information UI.

Solution:
Admins can manage field dependency rules by navigating to: Admin --> Configuration --> Field Dependencies. Create rules which allow the displaying of required document fields.
