折疊面板（Accordion）

在一個(gè)有限的空間內(nèi)顯示用于呈現(xiàn)信息的可折疊的內(nèi)容面板。

如需了解更多有關(guān) accordion 部件的細(xì)節(jié)，請查看 API 文檔折疊面板部件（Accordion Widget）。

默認(rèn)功能

點(diǎn)擊頭部展開/折疊被分為各個(gè)邏輯部分的內(nèi)容，就像標(biāo)簽頁（tabs）一樣。您可以選擇性地設(shè)置當(dāng)鼠標(biāo)懸停時(shí)是否切換各部分的打開/關(guān)閉狀態(tài)。

基本的 HTML 標(biāo)記是一系列的標(biāo)題（H3 標(biāo)簽）和內(nèi)容 div，因此內(nèi)容不用通過 JavaScript 即可用。

折疊內(nèi)容

默認(rèn)情況下，折疊面板總是保持一個(gè)部分是打開的。為了讓所有部分都是折疊的，可設(shè)置 collapsible 選項(xiàng)為 true。點(diǎn)擊當(dāng)前打開的部分，來折疊它的內(nèi)容面板。

自定義圖標(biāo)

通過 icons 選項(xiàng)自定義標(biāo)題圖標(biāo)，icons 選項(xiàng)接受標(biāo)題默認(rèn)的和激活的（打開的）狀態(tài)的 class。使用 UI CSS 框架中的任意 class，或者使用背景圖像創(chuàng)建自定義的 class。

填充空間

由于折疊面板是由塊級(jí)元素組成的，默認(rèn)情況下它的寬度會(huì)填充可用的水平空間。為了填充由容器分配的垂直空間，設(shè)置 heightStyle 選項(xiàng)為 "fill"，腳本會(huì)自動(dòng)設(shè)置折疊面板的尺寸為父容器的高度。
