```tsx
<RadioGroup.Root>
  <RadioGroup.Item value="1">織田信長</RadioGroup.Item>
  <RadioGroup.Item value="2">豊臣秀吉</RadioGroup.Item>
  <RadioGroup.Item value="3">徳川家康</RadioGroup.Item>
</RadioGroup.Root>
```

## 使い方

```tsx
import { Radio, RadioGroup } from "@yamada-ui/react"
```

```tsx
import { Radio, RadioGroup } from "@/components/ui"
```

```tsx
import { Radio, RadioGroup } from "@workspaces/ui"
```

```tsx
<RadioGroup.Root>
  <RadioGroup.Item />
</RadioGroup.Root>
```

### itemsを使う

```tsx
const items = useMemo<RadioGroup.Item[]>(
  () => [
    { label: "織田信長", value: "1" },
    { label: "豊臣秀吉", value: "2" },
    { label: "徳川家康", value: "3" },
  ],
  [],
)

return <RadioGroup.Root items={items} />
```

### バリアントを変更する

```tsx
const items = useMemo<RadioGroup.Item[]>(
  () => [
    { label: "Checked", value: "1" },
    { label: "No checked", value: "2" },
  ],
  [],
)

return (
  <VStack>
    <For each={["solid", "subtle", "surface", "outline"]}>
      {(variant, index) => (
        <RadioGroup.Root
          key={variant}
          variant={variant}
          defaultValue="1"
          items={items}
        />
      )}
    </For>
  </VStack>
)
```

### サイズを変更する

```tsx
const items = useMemo<RadioGroup.Item[]>(
  () => [
    { label: "Checked", value: "1" },
    { label: "No checked", value: "2" },
  ],
  [],
)

return (
  <VStack>
    <For each={["sm", "md", "lg"]}>
      {(size, index) => (
        <RadioGroup.Root
          key={size}
          size={size}
          defaultValue="1"
          items={items}
        />
      )}
    </For>
  </VStack>
)
```

### デフォルト値を設定する

デフォルト値を設定する場合は、`defaultValue`に値を設定します。

```tsx
const items = useMemo<RadioGroup.Item[]>(
  () => [
    { label: "織田信長", value: "1" },
    { label: "豊臣秀吉", value: "2" },
    { label: "徳川家康", value: "3" },
  ],
  [],
)

return <RadioGroup.Root defaultValue="1" items={items} />
```

### デフォルトで選択済みにする

デフォルトで選択済みにする場合は、`defaultChecked`を`true`に設定します。

```tsx
const items = useMemo<RadioGroup.Item[]>(
  () => [
    { defaultChecked: true, label: "織田信長", value: "1" },
    { label: "豊臣秀吉", value: "2" },
    { label: "徳川家康", value: "3" },
  ],
  [],
)

return <RadioGroup.Root items={items} />
```

### 方向を変更する

方向を変更する場合は、`orientation`に`"horizontal"`または`"vertical"`を設定します。デフォルトは`"vertical"`です。

```tsx
const items = useMemo<RadioGroup.Item[]>(
  () => [
    { label: "織田信長", value: "1" },
    { label: "豊臣秀吉", value: "2" },
    { label: "徳川家康", value: "3" },
  ],
  [],
)

return <RadioGroup.Root items={items} orientation="horizontal" />
```

### 形を変更する

形を変更する場合は、`shape`に`"circle"`や`"rounded"`などを設定します。デフォルトは`"circle"`です。

```tsx
const items = useMemo<RadioGroup.Item[]>(
  () => [
    { label: "織田信長", value: "1" },
    { label: "豊臣秀吉", value: "2" },
    { label: "徳川家康", value: "3" },
  ],
  [],
)

return (
  <VStack>
    <For each={["circle", "square", "rounded"]}>
      {(shape) => (
        <RadioGroup.Root
          key={shape}
          defaultValue="1"
          shape={shape}
          items={items}
        />
      )}
    </For>
  </VStack>
)
```

### 無効にする

無効にする場合は、`disabled`を`true`に設定します。

```tsx
<RadioGroup.Root>
  <For each={["solid", "subtle", "surface", "outline"]}>
    {(variant) => (
      <RadioGroup.Item key={variant} variant={variant} disabled>
        {toTitleCase(variant)}
      </RadioGroup.Item>
    )}
  </For>
</RadioGroup.Root>
```

### 読み取り専用にする

読み取り専用にする場合は、`readOnly`を`true`に設定します。

```tsx
<RadioGroup.Root>
  <For each={["solid", "subtle", "surface", "outline"]}>
    {(variant) => (
      <RadioGroup.Item key={variant} variant={variant} readOnly defaultChecked>
        {toTitleCase(variant)}
      </RadioGroup.Item>
    )}
  </For>
</RadioGroup.Root>
```

### 無効な入力にする

無効な入力にする場合は、`invalid`を`true`に設定します。

```tsx
<RadioGroup.Root>
  <For each={["solid", "subtle", "surface", "outline"]}>
    {(variant) => (
      <RadioGroup.Item key={variant} variant={variant} invalid>
        {toTitleCase(variant)}
      </RadioGroup.Item>
    )}
  </For>
</RadioGroup.Root>
```

### ボーダーの色を変更する

ボーダーの色を変更する場合は、`focusBorderColor`または`errorBorderColor`に値を設定します。

```tsx
<RadioGroup.Root>
  <RadioGroup.Item value="1">Default border color</RadioGroup.Item>
  <RadioGroup.Item focusBorderColor="green.500" value="2">
    Custom border color
  </RadioGroup.Item>
  <RadioGroup.Item errorBorderColor="orange.500" invalid value="3">
    Custom border color
  </RadioGroup.Item>
</RadioGroup.Root>
```

### カスタムコンポーネントを使う

```tsx
const { getInputProps, getLabelProps, getRootProps } = useRadioGroup({
  defaultValue: "1",
})

const CustomRadio = ({ children, ...rest }) => {
  return (
    <Box
      as="label"
      css={{
        "&:has(input:checked)": {
          bg: "colorScheme.solid",
          borderColor: "colorScheme.solid",
          color: "colorScheme.contrast",
        },
        alignItems: "center",
        borderWidth: "1px",
        display: "flex",
        h: "10",
        px: "3",
        rounded: "l2",
      }}
      {...getLabelProps()}
    >
      <Box as="input" {...getInputProps(rest)} />
      {children}
    </Box>
  )
}

return (
  <HStack {...getRootProps()}>
    <CustomRadio value="1">織田信長</CustomRadio>
    <CustomRadio value="2">豊臣秀吉</CustomRadio>
    <CustomRadio value="3">徳川家康</CustomRadio>
  </HStack>
)
```

### 制御する

```tsx
const [value, setValue] = useState("1")
const items = useMemo<RadioGroup.Item[]>(
  () => [
    { label: "織田信長", value: "1" },
    { label: "豊臣秀吉", value: "2" },
    { label: "徳川家康", value: "3" },
  ],
  [],
)

return <RadioGroup.Root items={items} value={value} onChange={setValue} />
```
