这是我的HTML:
<select id="ddlProducts" name="ddProducts">
<option>Product1 : Electronics </option>
<option>Product2 : Sports </option>
</select>
我想让产品的名称(即。'Product1'， 'Product2'，等等)，以及它的类别(即。电子，体育等)斜体，只使用CSS。我发现了一个老问题，提到这是不可能使用HTML和CSS，但希望，现在有一个解决方案。

一些属性可以为<option>标签设置样式:
字体类型 颜色 字体- * 背景颜色
此外，您可以使用自定义字体的个人<选项>标签，例如任何谷歌字体，材质图标或其他图标字体从icomoon或类似。(这可能会方便字体选择器等)
考虑到这一点，您可以创建字体家族堆栈，并在<option>标记中插入图标，例如。
<select>
<option style="font-family: 'Icons', 'Roboto', sans-serif;">a ★★★</option>
<option style="font-family: 'Icons', 'Roboto', sans-serif;">b ★★★★</option>
</select>
★取自Icons，其余取自Roboto。
注意，自定义字体并不适用于移动选择。
正如已经提到的，唯一的方法是使用一个插件来替换<select>功能。
jQuery插件列表:http://plugins.jquery.com/tag/select/
看一下使用Select2 plugin: http://jsfiddle.net/swsLokfj/23/的例子
即使没有太多的属性要改变，但你可以实现以下样式只有css:
.options { 边框:1px solid #e5e5e5; 填充:10 px; ｝ 选择{ 字体大小:14 px; 边界:没有; 宽度:100%; 背景:白色; ｝ < div class = "选项”> <选择> 苹果<选项值= " " > < /选项> 香蕉<选项值= " " > < /选项> 橙色<选项值= " " > < /选项> 芒果<选项值= " " > < /选项> < /选择> < / div >
Bootstrap允许你通过data-content使用样式:
<select class="selectpicker">
<option data-content="<span class='label label-success'>Relish</span>">Relish</option>
</select>
