jQuery UI 實例– 折疊面板（Accordion）
在一個有限的空間內顯示用於呈現信息的可折疊的內容面板。
如需了解更多有關accordion部件的細節，請查看API文檔折疊面板部件（Accordion Widget） 。
默認功能
點擊頭部展開/折疊被分為各個邏輯部分的內容，就像標籤頁（tabs）一樣。 您可以選擇性地設置當鼠標懸停時是否切換各部分的打開/關閉狀態。
基本的HTML 標記是一系列的標題（H3 標籤）和內容div，因此內容不用通過JavaScript 即可用。

折疊內容
默認情況下，折疊面板總是保持一個部分是打開的。 為了讓所有部分都是折疊的，可設置collapsible選項為true。 點擊當前打開的部分，來折疊它的內容面板。

自定義圖標
通過icons選項自定義標題圖標， icons選項接受標題默認的和激活的（打開的）狀態的class。 使用UI CSS 框架中的任意class，或者使用背景圖像創建自定義的class。

填充空間
由於折疊面板是由塊級元素組成的，默認情況下它的寬度會填充可用的水平空間。 為了填充由容器分配的垂直空間，設置heightStyle選項為"fill" ，腳本會自動設置折疊面板的尺寸為父容器的高度。
