Show or hide ViewApp navigation items

During runtime, ViewApp navigation items can be shown or hidden based on the access level assigned to, and/or user roles selected for, the navigation items. The navigation item will be visible only to logged in users who satisfy each of these conditions, if configured".

Controlling the display of content in a ViewApp by access levels or roles is an effective way of preventing access to a ViewApp's sensitive controls from unauthorized users. The following figures show a ViewApp to monitor tanks and filters in a water treatment plant. The ViewApp includes a Dashboards navigation item containing controls that regulate pump flow between tanks, which is the responsibility of supervisors in the plant's control room. Operators only need to see the status of filters and filtration units as part of their work responsibilities.

Navigation item security has been implemented for the Dashboards navigation item. The figure on the left shows the ViewApp navigation item shown to supervisors who need access to Dashboards controls. The ViewApp on the right hides the Dashboards navigation item from operators.
