I want to know if it is possible create a pop-up menu with right click in a web page using R-Shiny, and how create menu with submenus?
I was testing with this code but does not work:
selectInput("variable", "Variable:",
c(selectInput("variable1",Cylinders",c("cyl"="pm,"mmm"="jj"),
"Transmission" = "am",
"Gears" = "gear"))
