I continue to play with the dropdown. Node is configured to have its own label and it is properly displayed when starting node-red and dashboard (flowfuse, ver 1.29.0).
The value selection works fine, however I want to return the layout to the default (to show the label).
In the help, it says that by sending msg.payload with an empty array this is achieved. It doesn't work for me, except in the case when the option "Allow multiple selections from list" is selected in dropdown.
Is this expected behavior or a bug? Is there any other way to return the display to the initial one (to display the label)?
Thx
It works for me. Import this flow to see it.

Very fast 
and completely accurate 
! It works correctly, of course 
Thanks!
I left msg.payload as a string instead of JSON
