Choice
Ready

Choice buttons allow selection of a single or multiple options from a set of predefined options. They are a good alternative to radio buttons, checkboxes, and select menus.

You can set the type of the choice to be either a radio or a checkbox. Using radio type allows you to use Choice component inside Duet’s Choice Group.

`accessibleDescribedBy`	`accessible-described-by`	Indicates the id of a component that describes the choice. if this is set to an empty string it will prevent screenreaders from flowing to a collapsible content and can be used as an escape hatch if that behaviour is undesired.	`string`	`undefined`

Usage #

This section includes guidelines for designers and developers about the usage of this component in different contexts.

When to use #

To allow selection of a single or multiple options from a set of predefined options.
When you want to highlight the selection compared to regular radio and checkbox components.
When you have 6 or less options.

When not to use #

When you have more than 6 options. Prefer using either radio, checkbox or select component instead.
For “accepting terms of service” and similar functionality. Use checkbox component instead.

Accessibility #

This component has been validated to meet the WCAG 2.1 AA accessibility guidelines. You can find additional information regarding accessibility of this component below.

label property is always required for accessible choice control.
You can set the type of the choice to be either radio or checkbox. Depending on this selection we convey the selection type to assistive technologies as well. When type radio is chosen it is required to place choices inside Choice Group component.
Use accessibleLabel property to create a label for the choice that is only shown for screen readers. Typically, this label text replaces the visible text on the choice for users who use assistive technology.
disabled property makes the choice component disabled. This prevents users from being able to interact with the choice, and conveys its inactive state to assistive technologies.
accessibleActiveDescendant property can be used to indicate the id of a related component’s visually focused element.
accessibleControls property can be used to add an aria-controls attribute. Use the attribute to indicate the id of a component controlled by this component.
accessibleOwns property can be used to indicate the id of a component owned by the choice.
accessibleDescribedBy property can be used to indicate the id of a component which contains descriptive/help text related to the choice.
accessibleLabelInfoButton property can be used to change the aria-label of any info button.
please note: Avoid putting anything inside the unnamed slot in the component that is in the Shadow-dom (
for example), screenreaders behave badly in those scenarios, especially if collapsible is enabled
please note: When using the collapsible option with alot of focusable elements inside the Collapsible section, you should make sure to add a duet-caption in the header slot, this will then get assigned as the "describe-by" for the collapsible region

Additional considerations #

Consider positioning choices horizontally on larger viewports if surrounding space and label length allows it.
Please be aware that the more you hide inside an info or collapsible are, the harder it is to understand for a person using a screenreader.
Focus will be captured when an info section is displayed, an focus will be returned to the info button if the user Tabs out of the info area.
