sortableRadioButtons: Create radio buttons with sortable choices

Description

Create a set of radio buttons used to select an item from a list. The choices are sortable by drag and drop. In addition to the selected values stored in input$<inputId>, the server will also receive the order of choices in input$<inputId>_order.

Usage

sortableRadioButtons(
  inputId,
  label,
  choices = NULL,
  selected = NULL,
  inline = FALSE,
  width = NULL,
  choiceNames = NULL,
  choiceValues = NULL
)

Arguments

inputId

The input slot that will be used to access the value.

label

Display label for the control, or NULL for no label.

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). If this argument is provided, then choiceNames and choiceValues must not be provided, and vice-versa. The values should be strings; other types (such as logicals and numbers) will be coerced to strings.

selected

The initially selected value (if not specified then defaults to the first value)

inline

If TRUE, render the choices inline (i.e. horizontally)

width

The width of the input, e.g. '400px', or '100%'; see validateCssUnit().

choiceNames

List of names and values, respectively, that are displayed to the user in the app and correspond to the each choice (for this reason, choiceNames and choiceValues must have the same length). If either of these arguments is provided, then the other must be provided and choices must not be provided. The advantage of using both of these over a named list for choices is that choiceNames allows any type of UI object to be passed through (tag objects, icons, HTML code, ...), instead of just simple text. See Examples.

choiceValues

List of names and values, respectively, that are displayed to the user in the app and correspond to the each choice (for this reason, choiceNames and choiceValues must have the same length). If either of these arguments is provided, then the other must be provided and choices must not be provided. The advantage of using both of these over a named list for choices is that choiceNames allows any type of UI object to be passed through (tag objects, icons, HTML code, ...), instead of just simple text. See Examples.

Value

A set of radio buttons that can be added to a UI definition.
