checkboxInput: Checkbox and switch inputs

In nteetor/dull: A Reactive Web Framework Built on 'shiny'

Checkbox and switch inputs

Description

Reactive checkbox and checkbar inputs. Users may select one or more choices. The checkbox input appears as a standard checkbox or set of checkboxes. When a checkbox input has no selected choices the reactive value is NULL. Switch inputs differ from checkboxes only in appearance.

Usage

checkboxInput(
  ...,
  id,
  choices = NULL,
  values = choices,
  selected = NULL,
  inline = FALSE
)

updateCheckboxInput(
  id,
  choices = NULL,
  values = choices,
  selected = NULL,
  inline = FALSE,
  enable = NULL,
  disable = NULL,
  valid = NULL,
  invalid = NULL,
  session = getDefaultReactiveDomain()
)

switchInput(..., id, choices, values = choices, selected = NULL)

updateSwitchInput(
  id,
  choices = NULL,
  values = choices,
  selected = NULL,
  enable = NULL,
  disable = NULL,
  valid = NULL,
  invalid = NULL,
  session = getDefaultReactiveDomain()
)

Details

Getting started

Checkbox inputs may have a single possible value.

checkboxInput(
  id = NULL,
  choices = "Choice 1",
  selected = "Choice 1"
)

Choice 1

You may also specify multiple possible values.

checkboxInput(
  id = NULL,
  choices = c("Choice 1", "Choice 2", "Choice 3"),
  selected = c("Choice 1", "Choice 2")
)

Choice 1

Choice 2

Choice 3

Layout

While checkbox input choices are typically laid out vertically you can lay out the choices horizontally with inline = TRUE.

checkboxInput(
  id = NULL,
  choices = c("Choice 1", "Choice 2", "Choice 3"),
  inline = TRUE  # <-
)

Choice 1

Choice 2

Choice 3

Switch variant

The switch input functions identical to the checkbox input with a different appearance.

switchInput(
  id = NULL,
  choices = c("Toggle 1", "Toggle 2", "Toggle 3"),
  selected = "Toggle 2"
)

Toggle 1

Toggle 2

Toggle 3

Background color

Changing the background color of a checkbox or switch input will modify the background color of the selected choices.

checkboxInput(
  .style %>%
    background("warning"),
  id = NULL,
  choices = c("Choice 1", "Choice 2"),
  selected = c("Choice 1", "Choice 2")
)

Choice 1

Choice 2

switchInput(
  .style %>%
    background("success"),
  id = NULL,
  choices = c("Toggle 1", "Toggle 2"),
  selected = "Toggle 1"
)

Toggle 1

Toggle 2

Labelling

formGroup(
  label = "Label",
  checkboxInput(
    id = NULL,
    choices = c("Choice 1", "Choice 2")
  ),
  help = "Help text for the input"
)

Label

Choice 1

Choice 2
