Long Bottom Filter

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

1. Open the dashboard and switch to edit mode.
2. Click Add widget at the top, or the Add new widget icon in the center of the screen.
3. Open the Traditional SCADA fluid system widget bundle.
4. Select the filter widget for your use case.
5. Configure the widget settings, then click Add.

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.

Behavior parameters define how the widget responds to user interaction.
