Toolbar Input Select

Create a select input control that can be used to choose a single item from a list of values, suitable for use within a toolbar().

Usage

toolbar_input_select(
  id,
  label,
  choices,
  ...,
  selected = NULL,
  icon = NULL,
  show_label = FALSE,
  tooltip = !show_label
)

update_toolbar_input_select(
  id,
  label = NULL,
  show_label = NULL,
  choices = NULL,
  selected = NULL,
  icon = NULL,
  session = get_current_session()
)

Arguments

id

The input ID.

label

The input label. By default, label is not shown but is used by tooltip. Set show_label = TRUE to show the label (see tooltip for details on how this affects the tooltip behavior).

choices

List of values to select from. If elements of the list are named, then that name — rather than the value — is displayed to the user. It's also possible to group related inputs by providing a named list whose elements are (either named or unnamed) lists, vectors, or factors. In this case, the outermost names will be used as the group labels (leveraging the <optgroup> HTML tag) for the elements in the respective sublist. See the example section for a small demo of this feature.

...

Additional named arguments passed as attributes to the outer container div.

selected

The initially selected value. If not provided on input creation, the first choice will be selected by default. If provided in update_toolbar_input_select() with a new set of choices, it will replace the currently selected value.

icon

An icon. If provided without show_label = TRUE, only the icon will be visible.

show_label

Whether to show the label text. If FALSE (the default), only the icon is shown (if provided). If TRUE, the label text is shown alongside the icon. Note that show_label can be dynamically updated using update_toolbar_input_button().

tooltip

Tooltip text to display when hovering over the input. Can be:

• TRUE (default when show_label = FALSE) - shows a tooltip with the label text

• FALSE (default when show_label = TRUE) - no tooltip

• A character string - shows a tooltip with custom text

Defaults to !show_label. When a tooltip is created, it will have an ID of "{id}_tooltip" which can be used to update the tooltip text dynamically via update_tooltip().

session

A Shiny session object (the default should almost always be used).

Value

Returns a select input control suitable for use in a toolbar.

Details

When a tooltip is created for the select input, it will have an ID of "{id}_tooltip" which can be used to update the tooltip text dynamically via update_tooltip().

Functions

• toolbar_input_select(): Create a toolbar select input.

• update_toolbar_input_select(): Update a toolbar select input.

Updating toolbar select inputs

You can update the appearance and choices of a toolbar select input. This function works similarly to shiny::updateSelectInput(), but is specifically designed for toolbar_input_select(). It allows you to update the select's label, icon, choices, selected value, and label visibility from the server.

Note that you cannot enable or disable the tooltip parameter after the select has been created, only update the text of the tooltip. When a tooltip is created for the select input, it will have an ID of "{id}_tooltip" which can be used to update the tooltip text dynamically via update_tooltip().

For example:

library(shiny)
library(bslib)

ui <- page_fluid(
  toolbar(
    align = "right",
    toolbar_input_select(
      "select",
      label = "Choose",
      icon = bsicons::bs_icon("filter"),
      choices = c("A", "B", "C")
    ),
    toolbar_input_button(
      "change_choices",
      label = "Change Choices",
      show_label = TRUE,
      icon = bsicons::bs_icon("arrow-repeat")
    )
  ),
  verbatimTextOutput("value")
)

server <- function(input, output, session) {
  output$value <- renderPrint({
    input$select
  })

  observeEvent(input$change_choices, {
    update_toolbar_input_select(
      "select",
      label = "Pick one",
      choices = c("hi", "hello", "hey"),
      selected = "hello"
    )
    # Update the tooltip text
    update_tooltip("select_tooltip", "Choose your NEW option")
  })
}

shinyApp(ui, server)

    selected = "Option 2"
  )
