You can include the example by placing it inside a code block delimited by four backticks ````
. You can copy the template below and then paste in your Rmd contents.

Thanks a lot, @gadenbuie
Here you can see how under RMarkdown there is no ìnput$tags
object at all, which should respond to menu events.
This is the RMarkdown code with which I can't see any value of input$tabs
. I used textInput``` and
updateTextInputinside an observe because the
textOutput text is white and not visible on the sideBar. I have added an ````invalidateLater
to the ````observe`` so that it is clear that it does not react at all to menu item selection.
