When setting up multi-level selector pages, it is possible to display nested selectors as filters at the top of the screen.

To do this, in the Service menu > Settings > Visualization, enable the Show filter for subselectors (Parent subselector should include the extended property ismixedview=1) option.

• If the option is disabled, the subselector filter is not displayed
  
• When enabled, a sub-selector filter is displayed at the top of the screen with the ability to switch between them.
