Short Bottom Filter

The Short bottom filter widget renders a compact vertical filter symbol with the pipe connection at the bottom. Use it to represent a filter unit in a fluid system diagram where vertical space is limited.
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.
