jQuery UI 實例 – 折叠面板（Accordion）
jQuery UI 實例 - 折叠面板（Accordion）
在一個有限的空間內顯示用於呈現信息的可折叠的內容面板。
如需了解更多有關 accordion 部件的細節，請查看 API 文檔 折叠面板部件（Accordion Widget）。
默認功能
點擊頭部展開/折叠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。

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

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
由於折叠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"，腳本會自動設置折叠面板的尺寸為父容器的高度。
