Generally, Form rule works only during the request creation/editing via web form and not at the request details page.
Form rules have been configured to add and remove options based on conditions. However, if an end user selects an incorrect condition and clears it, the options remain visible.
Key Considerations:
FAFR (Field and Form Rules) function as designed and cannot predict incorrect selections to automatically revert options.
To handle this scenario, create a counter rule for each form rule to remove the options when the condition is no longer met.
Refer to the sample below for implementation details.
