In (Fusion HCM)Seniority Date Page How to hide custom field based on selected Rule from Drop Down

REQURIMENT:

When we select the Rule Is Job Seniority Date section from the drop-down list then the custom field is Seniority Date report needs to be visible under Seniority Dates Section, when we select other than Job Seniority Date section from the drop down list then that custom field is Seniority Date report should not be visible.
