@volvo-cars/react-headless

A collection of headless (style-free) React hooks that add accessibility and behaviour to native HTML elements. Use these hooks to build fully custom-styled components that follow Design System interaction patterns.

These hooks follow a specific pattern: they return props objects (e.g. dialogProps, tabProps) that are spread directly onto DOM elements. The hooks handle interaction, accessibility, and state — but never render any UI themselves. For general-purpose utility hooks that are not tied to a specific UI pattern or DOM element, see @volvo-cars/react-utils.
