updateOrderInput: Change the value of an orderInput on the client
In shinyjqui: 'jQuery UI' Interactions and Effects for Shiny

Description Usage Arguments Examples

Similar to the input updater functions of shiny package, this function send a message to the client, telling it to change the settings of an orderInput object. Any arguments with NULL values will be ignored; they will not result in any changes to the input object on the client. The function can't update the "source" orderInputs.

updateOrderInput(
  session,
  inputId,
  label = NULL,
  items = NULL,
  connect = NULL,
  item_class = NULL
)

`session`	The `session` object passed to function given to `shinyServer`.
`inputId`	The `input` slot that will be used to access the current order of items.
`label`	Display label for the control, or `NULL` for no label.
`items`	Items to display, can be a list, an atomic vector or a factor. For list or atomic vector, if named, the names are displayed and the order is given in values. For factor, values are displayed and the order is given in levels
`connect`	Optional. Allow items to be dragged between `orderInput`s. Should be a vector of `inputId`(s) of other `orderInput`(s) that the items from this `orderInput` should be connected to.
`item_class`	One of the Bootstrap color utility classes to apply to each item.

library(shiny)

if (interactive()) {

  ui <- fluidPage(
    orderInput("foo", "foo",
               items = month.abb[1:3],
               item_class = 'info'),
    verbatimTextOutput("order"),
    actionButton("update", "update")
  )

  server <- function(input, output, session) {
    output$order <- renderPrint({input$foo})
    observeEvent(input$update, {
      updateOrderInput(session, "foo",
                       items = month.abb[1:6],
                       item_class = "success")
    })
  }
