closing sidebar in shiny dashboard - r

Question

I am trying to make a multipage shiny dashboard. I would like the sidebar to collapse when you pick a page, with the ability to reopen it to pick a new page. For example, when you pick page 2 the sidebar collapses and you can reopen it later if you want to go back to page 1. Right now it is stuck open, i.e. when you click page 2 the sidebar does not collapse. I used useShinyjs(), which is what I thought makes it collapsible with no luck. Any help is much appreciated :)

Only using useShinyjs() doesn't do the trick. It only sets up shinyjs, but you need to tell it what to do. The idea here is to add the class "sidebar-collapse" to the body, as this hides the sidebar. The sidebar should always been hidden if a tab was switched, so have to add an observer that listens if a tab was switched. Then you can use shinyjs to add the class with addClass. The input of the tabswitch is the id of the sidebarMenu:

BTW: you also need the package shinydashboardPlus. Also, I removed your observer because I don't know what you want to achieve. Lastly, I reduced the width of the header, because otherwise the button to show the sidebar is hidden.
For more information how it works, have a look here and here.
