# Radio

A group of mutually exclusive options with keyboard navigation.

## Install

```sh
npx shadcn@4.21.0 add lr-run/dir-ui/radio#v0.1.3
```

[Registry item with source and dependencies](https://github.com/lr-run/dir-ui/blob/v0.1.3/registry.json)

Requires React 19, Tailwind CSS 4 and shadcn initialized with Base UI. Registry target placeholders resolve through components.json: @ui, @components, @hooks and @lib. Imports below use the conventional @/ prefix for illustration; the CLI rewrites them to your configured aliases. Shared components are installed once through registryDependencies. The installer merges shared theme rules into the stylesheet configured in components.json. Existing files are never forcibly overwritten; review CLI conflicts before accepting changes. No Dir runtime is required.

The registry item installs Base UI and shared theme styles. Compose RadioGroup and Radio.Root directly.
