页面内容没有更改下拉列表？
我想设置页面显示：相对于下拉列表。当它处于活动状态时=意味着当我点击下拉主按钮查看列表时，表示其他内容将随之改变。
像=＆GT;
我想要上面的东西，但是不能这样做，而且到目前为止我做的工作......
看看我的其他页面内容落后于列表...... 但是我想要一些像我的2张照片...
我的HTML ..＆gt;

你需要添加jquery来测试thr代码......
我认为html和js都没有问题，只有css.so css专家请帮助我。看到一个大的代码后就跑掉了......就是css ......
1 个答案:
答案 0 :(得分：0)
如果是margin-bottom状态，只需将active添加到您的下拉类。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;
}
试过这个并且它有效。调整底部边距的值以满足您的需要。希望这可以帮助。
