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, selectize = TRUE, width = NULL, size = NULL)
selectizeInput(inputId, ..., options = NULL, 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?
selectize
Whether to use selectize.js or not.
width
The width of the input, e.g. '400px', or '100%'; see validateCssUnit.
size
Number of items to show in the selection box; a larger number will result in a taller box. Not compatible with selectize=TRUE. Normally, when multiple=FALSE, a select input will be a drop-down list, but when size is set, it will be a box instead.
...
Arguments passed to selectInput().
options
A list of options. See the documentation of selectize.js for possible options (character option values inside I() will be treated as literal JavaScript code; see renderDataTable() for details).

Value

A select list control that can be added to a UI definition.

Details

By default, selectInput() and selectizeInput() use the JavaScript library selectize.js (https://github.com/brianreavis/selectize.js) to instead of the basic select input element. To use the standard HTML select input element, use selectInput() with selectize=FALSE.

In selectize mode, if the first element in choices has a value of "", its name will be treated as a placeholder prompt. For example: selectInput("letter", "Letter", c("Choose one" = "", LETTERS))
