Installation

pnpm dlx shadcn@latest add @sc1m/radio

This also merges the token layer and installs src/lib/cn.ts plus @base-ui/react. For the manual route — prerequisites, components.json, and app-level setup — see Installation.

Usage

import { Radio } from "@/components/ui/radio";

Example

The preview above, with its source. This is the demo module verbatim, so the code and the thing it renders cannot drift apart.

smallmediumlarge

<RadioGroup defaultValue="small" aria-label="Size">
  {['small', 'medium', 'large'].map((size) => (
    <label key={size} className="flex items-center gap-2 text-sm">
      <Radio value={size} />
      {size}
    </label>
  ))}
</RadioGroup>

API reference

Each part forwards every prop of its Base UI counterpart; the tables list the ones declared on the part itself. See Base UI's reference for the inherited element props.

PropTypeDefaultDescription

valueValue—The unique identifying value of the radio in a group.

disabledboolean—Whether the component should ignore user interaction.

requiredboolean—Whether the user must choose a value before submitting a form.

readOnlyboolean—Whether the user should be unable to select the radio button.

inputRefReact.Ref<HTMLInputElement>—A ref to access the hidden input element.

Accessibility

Behaviour, focus management, and ARIA wiring come from Base UI's Radio — see its reference for the full keyboard map.

Keyboard focus draws a 2px ring in --ring, never removed — only shown on :focus-visible, so a pointer press does not paint one.
Disabled parts mute their contents rather than the element, keeping the focus ring at full strength where the part stays focusable.

Design tokens

The component reads semantic tokens only — no raw colour, radius, or duration appears in its source. Override the token, not the component.

TokenApplied to

--accentRadio

--line-strongRadio

--ringRadio

--surface-raisedRadio

Source

src/components/ui/radio/radio.tsx — no next/* imports, so it drops into any React 19 + Tailwind v4 app.
