List of topic choices in mqtt-in

General
6

You can use a subflow to do this.

  1. Set the mqtt-in topic to ${TOPIC}
  2. Wrap that node in a subflow.
  3. Edit the subflow properties and define a property called TOPIC. By expanding the row in the properties table, you can customise the UI for how the property will be shown. One of the options is a select box where you can predefine a set of options.
