jQuery UI サンプル -アコーディオン（Accordion）

デフォルト機能

ヘッダーをクリックすると、タブ（tabs）のように論理的なセクションに分かれたコンテンツを展開/折りたたみできます。マウスホバー時に各セクションの開閉状態を切り替えるかどうかをオプションで設定できます。

基本的なHTMLマークアップは一連の見出し（H3タグ）とコンテンツdivで構成されているため、JavaScriptを使わなくてもコンテンツが利用可能です。

コンテンツの折りたたみ

デフォルトでは、アコーディオンは常に1つのセクションが開いた状態を保ちます。すべてのセクションを折りたたむには、collapsibleオプションをtrueに設定します。現在開いているセクションをクリックすると、そのコンテンツパネルが折りたたまれます。

カスタムアイコン

次のiconsオプションでヘッダーアイコンをカスタマイズし、iconsこのオプションは、ヘッダーのデフォルト状態とアクティブ（開いている）状態のclassを受け付けます。UI CSSフレームワークの任意のclassを使用するか、背景画像を使ってカスタムclassを作成できます。

スペースを埋める

アコーディオンはブロックレベル要素で構成されているため、デフォルトではその幅は利用可能な水平スペースを埋めます。コンテナによって割り当てられた垂直スペースを埋めるには、heightStyleオプションを"fill"に設定すると、スクリプトは自動的にアコーディオンのサイズを親コンテナの高さに設定します。
