這是本人自己用jq寫(xiě)的折疊菜單,

折疊速度還可以在jq的slideToggle上調(diào)整，

加入了點(diǎn)擊標(biāo)題改變樣式效果

*html

<div class="zhedie">
    <ul>
        <li>
            <div class="biaoti">標(biāo)題1</div>
            <div class="neirong">內(nèi)容1</div>
        </li>
        <li>
            <div class="biaoti">標(biāo)題2</div>
            <div class="neirong">內(nèi)容2</div>
        </li>
        <li>
            <div class="biaoti">標(biāo)題3</div>
            <div class="neirong">內(nèi)容3</div>
            </li>
    </ul>
</div>
