Question

我有一个使用ul和li（jsfiddle）的下拉列表的jsfiddle。当尝试将其转换为选择选项下拉列表时，我没有得到相同的选项（[jsfiddle]）2。我猜测它与我重命名CSS的方式有关（我只是用选项替换了li）但我不确定它有什么问题。我当前的HTML和CSS在下面，文本中有两个jsfiddles。

HTML

<div class="dd wrapper-dropdown-3" tabindex="1">
    <select id="Process" class="dropdown" name="Process" data-val-required="Required" dataval="true">
        <option value="">--- Select One ---</option>
        <option value="Extrusion"><a href="#">Extrusion</a></option>
        <option value="Injection"><a href="#">Injection</a></option>
        <option value="Secondary"><a href="#">Secondary</a></option>
        <option value="Vinyl Dip Molding"><a href="#">Vinyl Dip Molding</a></option>
    </select>
</div>

CSS

.wrapper-dropdown-3 {
    /* Size and position */
    position: relative;
    width: 200px;
    margin: 0 auto;
    padding: 10px;

    font-weight: normal;
    list-style: none;

    opacity: 0;
    pointer-events: none;
    /*Gets rid of the padding where the bullets would be*/

    border-width: 0 8px 8px 8px;
    border-style: solid;
    border-color: rgba(0, 0, 0, 0.1) transparent;
}
.wrapper-dropdown-3.active .dropdown {
    opacity: 1;
    pointer-events: auto;
}

Answer 1

pointer-events: none;导致了这个问题。用提供的css替换以下类：

.wrapper-dropdown-3 .dropdown {
position: absolute;
width: 100%;
top: 0;
left: 0;
right: 0;
background: white;
border-radius: inherit;
border: 1px solid rgba(0, 0, 0, 0.17);
box-shadow: 0 0 5px rgba(0, 0, 0, 0.1);
font-weight: normal;
list-style: none;
opacity: 0;
padding-left: 0;
}

不确定为什么你有一个指针事件，因为它不允许你与元素交互。

Answer 2

您需要做一些事情来解决您的问题。所有这些都在你的.wrapper-dropdown-3 .dropdown样式中。首先，删除pointer-events: none作为@ramesh提及。然后将top: 100%;更改为top: 0;。添加width: 100%;。将opacity: 0;更改为opacity: 1;，以便您可以看到它。删除边框，选择已有边框。最后，添加以下内容以从Firefox中删除默认下拉箭头：

-moz-appearance: none;
text-indent: 0.01px;
text-overflow: '';
