Note that this id can be used to show/hide this modal with the appended jQuery methods show/hide.

...

modal_args

(list) optional list of arguments for the shiny::modalDialog function to customize the modal. Has easyClose set to TRUE as default

Value

# nolint start
library(shiny)
ui <- fluidPage(
  shinyjs::useShinyjs(),
  actionButton("show_1", "$('#modal_1').modal('show')"),

      size = "l",
      title = "First Modal",
      easyClose = TRUE,
      footer = NULL
    ),
    tags$div(
      "This modal can be closed by running", tags$code("$('#modal_1').modal('hide')"),
      "in the JS console!",
      tags$br(),
      "Note that the second modal is placed right within this modal",
      tags$br(),
