checkboxGroupInput: Checkbox Group Input Control

Description

Create a group of checkboxes that can be used to toggle multiple choices independently. The server will receive the input as a character vector of the selected values.

Usage

checkboxGroupInput(inputId, label, choices, selected = NULL, inline = 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 show checkboxes for. If elements of the list are named then that name rather than the value is displayed to the user.

selected

The values that should be initially selected, if any.

inline

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

width

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

Value

A list of HTML elements that can be added to a UI definition.
