Example uses:

  • create an e-commerce facet like search experience.
  • create a filter for airlines to fly by in a flight booking experience.


  title="MultiList: City Filter"
  defaultSelected={["San Francisco"]}
  searchPlaceholder="Search City"

    unique id of the sensor, can be referenced in an actuator’s actuate prop.
