在一個有限的空間內(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）。
點擊頭部展開/折疊被分為各個邏輯部分的內(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。
