RadioGroup
Mutually exclusive choices with room to explain what each choice means.
Live — this one is real
Usage
"use client";
import { useState } from "react";
import { RadioGroup } from "mizu-ui";
export function Example() {
const [value, setValue] = useState("local");
return (
<RadioGroup
label="Storage"
value={value}
onValueChange={setValue}
options={[
{ value: "local", label: "Local", description: "On this device" },
{ value: "cloud", label: "Cloud", description: "Across devices" },
]}
/>
);
}
It starts with "use client" because it keeps state or passes functions to components, so it pastes into a Next.js page as it is. Other React setups ignore the directive.
Source & setup
Add this component to your project with the shadcn CLI. The command copies its source into your configured UI directory, with base.css, Mizu’s tokens, and the stylesheets that hold its rules. Each rule lives in one stylesheet, so components you add together never repeat CSS. In a project without a components.json, run npx shadcn@latest init 0xuser64bit/mizu/preset first: plain init installs shadcn’s theme into your global CSS. Then load the fonts.
npx shadcn@latest add 0xuser64bit/mizu/radio-groupEvery component imports from its own path, its name in kebab case. Its source, forms/Selection.tsx, also holds SegmentedControl, NumberField, Rating and ColorPicker. Each has its own command and path; adding one after this copies only its small entry file. To paste the example, replace its mizu-ui import with:
import { RadioGroup } from "@/components/ui/mizu/radio-group";For npm imports, import mizu-ui/styles.css once. Fonts are optional via mizu-ui/fonts.css. Override --mizu-* tokens or use className for local styling. Uses native React and CSS; install the package peers for root imports. A Client Component: its source starts with “use client”.
Inspect forms/Selection.tsx
Source is included in the npm package under src/forms/Selection.tsx.
Props
| Prop | Type | Default | Description |
|---|---|---|---|
| options | Choice[] | — | Value, label, optional description and disabled. |
| value / onValueChange | string / function | — | Controlled selection. |
| name | string | — | Form field name. Unique by default. |
Accessibility
Fieldset/legend and native radios supply group semantics and arrow-key behavior.
Motion
CSS transitions explain state changes. Reduced motion removes travel.
