Blur 'HTML' Elements in 'Shiny' Applications Using 'Spoiler-Alert.js'

It can be useful to temporarily hide some text or other HTML elements in 'Shiny' applications. Building on 'Spoiler-Alert.js', it is possible to select the elements to hide at startup, to partially reveal them by hovering them, and to completely show them when clicking on them.

spoiler

The goal of {spoiler} is to blur any HTML elements (text, plots, etc.) in R Shiny apps, so that spoilers are avoided.

Installation

You can install the GitHub version of {spoiler} with:

  column(
    4,
    spoiler(plotOutput("test"))
  ),
  hide_spoilers(max = 10, partial = 4)
)

server <- function(input, output, session) {
  
  output$test <- renderPlot(plot(mtcars$mpg))
  
}
