@Buckskin The new option can be shown by adding a msg.payload value to the new option. For example, you can use msg.payload=2700, which will show the new option.
@joepavitt There is a minor bug: In dynamic dropdown, when user selects a dropdown item, the msg.options is also passed through to the dropdown output. This should be removed to improve efficiency. We could have thousands of items in the msg.options.
