| Prop | 型 | 既定値 | 説明 |
|---|---|---|---|
id* | string | — | 内部の<details>要素のID。 |
label* | ReactNode | — | 領域を開閉するsummaryの内容。 |
content* | ReactNode | — | 領域を開くと表示するパネルの内容。 |
defaultOpen | boolean | false | 初回レンダリング時に開く項目。非制御なのでJavaScriptなしでも維持されます。 |
disabled | boolean | false | 切り替えをブロックし、summaryにaria-disabledとdata-disabledを設定します。 |
className | string | — | <details>ルートに適用するクラス。 |

アクセシビリティ
可能な限りセマンティックHTMLを使います。プレイグラウンドで描画されたマークアップを確認できます。ARIAはネイティブ要素だけでは足りない場合にのみ追加します。
