Create a select list input control — selectInput • shiny.semantic

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: The initially selected value (or multiple values if multiple = TRUE). If not specified then defaults to the first value for single-select lists and no values for multiple select lists.
multiple: Is selection of multiple items allowed?
width: The width of the input.
...: Arguments passed to dropdown_input.
