Changing section visibility
Use When rules to determine which layouts and sections are visible. For example, if you are a manager, modify the visibility of a section to ensure that only a manager can see the content of the section.
In Dev Studio, access the section for which you want to change visibility.
Click anywhere inside the section and then click the View properties icon.
From the Visibility drop-down list, select Condition.
Enter a When rule or a conditional expression.
Click OK and then click Save.
