如何在表单中设置禁用选项的样式 [英] How to style Disabled Options in a form

问题描述

我正在使用带有下拉菜单的表单，该菜单包含一些已禁用的选项，因此用户无法选择它们.我试图通过CSS来自定义这些元素，但Chrome和IE7/8/9/10出现了一些问题.

I'm using a form with a drop-down menu that contains some options disabled, so the users cannot select them. I'm trying to customize via css these elements but I have some problems with Chrome and IE7/8/9/10.

HTML:

<div class="formBody">
    <select  name="form[categoria][]"  id="categoria"  class="rsform-select-box">
      <option selected="selected" value="">Scegli una categoria</option>
      <option disabled="disabled" value="">Impresa </option>
    </select>
    <span class="formValidation">
        <span id="component50" class="formNoError">Scegli una categoria</span>
    </span>
</div>

CSS:

select option[disabled] { color: #000; font-weight: bold }

此代码仅适用于Firefox，不适用于Chrome和IE(所有版本).

This code works only with Firefox and doesn't work with Chrome and IE (all version).

有解决这个问题的主意吗?

Any idea to solve this problem?
