我有一些代码使用ul和li Here is the first jsfiddle生成下拉列表。这就是我希望看到下降的方式。但是,当我尝试将它们转换为选择和选项下拉列表时,我正在接收以下格式current jsfiddle。我所做的只是替换第一个小提琴中的li选项。任何想法如何解决这个或为什么这样做?似乎忽略了我所取代的一切

答案 0 :(得分:0)
您已指定了一个类名=&#34; wrapper-dropdown-3下拉&#34;但是你的CSS中没有一部分可以为这个类设置样式。此外,在CSS中进行样式设置时,应注意HTML DOM结构。例如,在代码中:
<ul class="ul">
<li class="li"></li>
</ul>
你会有一个像这样的CSS:
.ul{/*CSS code*/}
和
.ul .li{/*CSS code*/}
而不是
.li{/*CSS code*/}
因为 li 标记位于 ui 标记内
