## Using Fomantic UI JavaScript elements [Advanced]

Some Fomantic UI elements require to run a specific JS code when DOM document is ready. There are at least 2 options to do this:

1. Use `shinyjs`

    library(shinyjs)
    ...
    jsCode <- " # Fomantic UI componts JS "
    ...
    ui <- function() {
      shinyUI(
        semanticPage(
          title = "Your page title",
          shinyjs::useShinyjs(),
          # Your UI code
        )
      )
    }
    server <- shinyServer(function(input, output) {
      runjs(jsCode)
      # Your Shiny logic
    })
    shinyApp(ui = ui(), server = server)

2. Use `shiny::tags$script()`

    ...
    jsCode <- "
    $(document).ready(function() {
      # Semantic UI components JS code, like:
      #$('.rating').rating('setting', 'clearable', true);
      #$('.disabled .rating').rating('disable');
    })
    ...
    "

    ui <- function() {
      shinyUI(
        semanticPage(
          title = "My page",
          tags$script(jsCode),
          # Your UI code
        )
      )
    }
    ...
    server <- shinyServer(function(input, output) {
      # Your Shiny logic
    })

    shinyApp(ui = ui(), server = server)
