你需要添加jquery来测试代码......

我认为这对html和js没有问题,只有css.so css专家请帮助我。看到一个大代码后就跑掉了......是css ...

jquery html css

如果是margin-bottom状态,只需将active添加到您的下拉类中。以下代码应解决此问题:

    .wrapper-dropdown-5.active {
        border-radius: 5px 5px 0 0;
        background: #4cbeff;
        box-shadow: none;
        border-bottom: none;
        color: white;
        margin-bottom: 200px;
    }

试过这个,它的确有效。调整底部边距的值以满足您的需要。希望这可以帮助。
