Wish to expand shiny dashboard box

Anyone on this board have any success in developing code to expand box on shinydashboard? I've seen some code through shinyjs that allows for collapsing boxes but none that allow for full page or a prespecified percent zoom of a certain box on a dashboard page. Microsoft, Google, et. al. have figured out how to minimize, expand, and close documents with a simple selection feature, yet shiny apps only can minimize without additional CSS or JS help.
