I need assistance removing the entire wellpanel in my shiny app using the removeUI() function. I am unsure of what selector to use for this task. Any guidance on this matter would be greatly appreciated.
If you design the user interface first and then launch a Shiny application in a web browser, you can inspect the elements to find that the wellPanel is assigned a class = well.

One approach is to define the selector with the specific class name, such as .class_name. In this scenario, it would be: selector = ".well".
Below is a basic example of a Shiny app that deletes a single wellPanel from a page using the specified class:
library(shiny)
ui <- fluidPage(
wellPanel(
"This content will 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)
