javascript - 选择箭头样式更改时 <选择多个 ="multiple">

Question

我找到了很多关于如何更改 a 的箭头颜色的教程，但是当 multiple 设置为 multiple="multiple"并且我有两个箭头而不是一个时，它们不起作用。

网站是textatradesman.com，HTML如下:

<select id="select" multiple="multiple">  
                <option class="clicktoselect" value="">Click or Tap to Select</option>

         </select>

Answer 1

是的。

简单 <select>有一个箭头。多个 <select>有两个箭头。有什么问题？如果你不喜欢箭头，你可以添加一个组合插件，比如 chosen或 select2来自 jquery。

您可以更好地解释问题以及您希望实现的目标。
