折疊面板（Accordion）
在一個有限的空間內顯示用於呈現資訊的可折疊的內容面板。
如需了解更多有關 accordion 元件的細節，請查看 API 文件 折疊面板元件（Accordion Widget）。
預設功能
點擊頭部展開/折疊被分成各個邏輯部分的內容，就像標籤頁（tabs）一樣。您可以選擇性地設定當滑鼠懸停時是否切換各部分的開啟/關閉狀態。
基本的 HTML 標籤是一系列的標題（H3 標籤）和內容 div，因此內容不用通過 JavaScript 即可使用。

填滿空間
由於摺疊面板是由區塊級元素組成的，預設情況下它的寬度會填滿可用的水平空間。為了填滿由容器指派的垂直空間，設定 heightStyle 選項為 "fill"，腳本會自動設定折疊面板的尺寸為父容器的高度。
