Dashboard 2.0 : Dropdown node need to be cleared

General
1

I am using a dropdown node to select shift. however after pressing the save button, I want to clear the selction at the drop down node. I tried to pass msg.payload = null but it does not work. in the dashboard, it still shows previous selection. I want to show 'Select Shift' in the dropdown and pass a msg.payload = null to the output of dropdown node.
my code is as below:

Scratch that, i miss read your question.
I see no way to do this.
Maybe check nodes github page and if no feature request or issue raise about this, raise one.
@joepavitt is it possible to reset/ delete the select dynamically?

[edit]
Ok it is possible you have to send.
From help text

To clear any selection for a dropdown, pass an empty array [] as msg.payload.

{"payload": []}

e.g.

[{"id":"51587e11e529df89","type":"ui-dropdown","z":"d1395164b4eec73e","group":"a007140ec55da7a5","name":"","label":"Shift","tooltip":"","order":1,"width":"2","height":"1","passthru":true,"multiple":false,"chips":false,"clearable":true,"options":[{"label":"A","value":"A","type":"str"},{"label":"B","value":"B","type":"str"}],"payload":"","topic":"payload","topicType":"msg","className":"","typeIsComboBox":true,"x":650,"y":100,"wires":[[]]},{"id":"44381009169d1a71","type":"inject","z":"d1395164b4eec73e","name":"","props":[{"p":"payload"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"[]","payloadType":"json","x":190,"y":100,"wires":[["51587e11e529df89"]]},{"id":"a007140ec55da7a5","type":"ui-group","name":"New Plan","page":"68dd494046ff8789","width":"12","height":"1","order":1,"showTitle":true,"className":"","visible":"true","disabled":"false"},{"id":"68dd494046ff8789","type":"ui-page","name":"Production Plan","ui":"1805777f90e92057","path":"/productionplan","icon":"home","layout":"grid","theme":"e384268359403859","order":3,"className":"","visible":"true","disabled":"false"},{"id":"1805777f90e92057","type":"ui-base","name":"dashboard","path":"/dashboard","includeClientData":true,"acceptsClientConfig":["ui-notification","ui-control"],"showPathInSidebar":false},{"id":"e384268359403859","type":"ui-theme","name":"Default Theme","colors":{"surface":"#ffffff","primary":"#0094CE","bgPage":"#eeeeee","groupBg":"#ffffff","groupOutline":"#cccccc"},"sizes":{"density":"default","pagePadding":"12px","groupGap":"12px","groupBorderRadius":"4px","widgetGap":"12px"}}]
