You cannot.
Function nodes run server side (in the nodejs runtime)
Dashboard runs client side (in a remote browser)
What you could probably do:
- write a ui-template that handles messages on input
- wire an msg input into the ui-template
- In t he template code:
- if the `msg.topic` (or payload or whatever) matches some criteria you determine means "close the sidebar), simulate a click on the menu element (not tested, not guaranteed to work)
- You will also need to inspect the menu elements and figure out what classes/props/attributes identify it as being open before sending a `click` event to avoid getting out-of-step
If you _need_ this level of feature built in, then please raise an issue on the dashboard repository. I suspect this would be somthing that `ui_control` would have to have programmed support for.
