selectInput: Create a select list input control

selectCLInputR Documentation

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

selectCLInput(input_id, label, choices, selected = NULL, multiple = FALSE)

Arguments

input_id

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. 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.

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?

Examples

selectCLInput(
  "letter",
  "Select a letter",
  LETTERS
)
