Short Top Filter

This widget belongs to the Traditional SCADA fluid system bundle — a collection of pipe segments, fittings, valves, pumps, and gauges designed for building fluid system diagrams on ThingsBoard dashboards. It renders a static filter symbol and triggers a configurable dashboard action when clicked.

• Place a visual filter element in a fluid system diagram.
• Trigger a dashboard action when the widget symbol is clicked.

The widget can optionally connect to a Device or an Entity alias. A device connection is only needed when the On click action requires entity context, such as navigating to a device-specific dashboard state or passing an entity to another dashboard.

The SCADA symbol defines the visual shape of the widget. Each filter widget has a pre-selected symbol from the Traditional SCADA fluid system bundle. To use a different symbol, click Browse SCADA symbol from gallery and choose one from the library, or upload your own.
