Is there a way to hide/disable the `Close` button on a `bsModal` window?

Question

A bsModal window in shiny app comes with a default Close button. Is there a way that can be disabled? I tried to look up on SO for similar

Answer 1

This should do it

library(shiny)
library(shinyBS)

if(interactive()){
  shinyApp(
    ui <- fluidPage(
      actionButton("open", "Open"), #action button to trigger the modal window.
      bsModal("id1", "Box 1", "open", size = "small",
              HTML(paste("A simple modal window.")),
              tags$head(tags$style("#id1 .modal-footer{ display:none}"))
      )
    ),

    server <- function(input,output,session){

    }
  )
}
