Build nested navigation for a large PI Vision display estate without JSON or code. Construct unlimited menu hierarchies in the Format panel, choose icons from the built-in library, and flip the whole menu between a horizontal top bar and a vertical side menu in one click. Paste the same menu on every display and it highlights itself: the symbol reads the current display URL and marks the matching item and its parent group. Bind tags to menu items and the menu doubles as a live plant status board, so operators see where the problem is before they navigate to it.
