Answer 1

Perhaps you could work with a toggle-button (e.g. named "set parameters") which opens or closes a conditionalPanel. Such panel then disappears or pops-up when needed. See: https://shiny.rstudio.com/reference/shiny/0.13.2/conditionalPanel.html

Answer 2

Only a partial solution but ... if you wrap the div below around the content or your sidebarPanel

div(id = "demo", class = "collapse in", 

)

and then put a button in your main panel as follows

HTML("<button type='button' class='btn btn-danger' data-toggle='collapse' data-target='#demo'>simple collapsible</button>"),

you can collapse the content of the sidebarPanel. This doesn't expand the main panel to take up all the screen however.
