selectInput: Create a select list input control

Description

Create a select list that can be used to choose a single or multiple items from a list of values.

Usage

selectInput(
  inputId,
  label,
  choices,
  selected = NULL,
  multiple = FALSE,
  width = 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.

selected

multiple

Is selection of multiple items allowed?

width

The width of the input.

...

Arguments passed to dropdown_input.
