Removing WellPanel using removeUI

Question

I am trying to remove the entire wellpanel using removeUI() in my shiny app. I'm not sure what to be used as a selector. Can anyone help me in this regard?

If you create the UI and then open up a Shiny app in a browser and use inspect element you can see that wellPanel has a class = well

So one possibility is to specify the class a selector like .class_name. In your case it is: selector = ".well".

Here is a minimal Shiny app that removes a single wellPanel from a page using class

library(shiny)

ui <- fluidPage(
  wellPanel(
    "This is going to be removed",
    plotOutput("plot")
  ),

  actionButton("btn", "Remove wellPanel")
)

server <- function(input, output, session) {
  output$plot <- renderPlot(plot(iris))

  observeEvent(input$btn, {
    removeUI(selector = ".well")
  })
}

shinyApp(ui, server)
