html - 为什么在Firefox中没有用于选择的水平滚动条

为什么在FireFox中没有用于此类选择的水平滚动条？

<select style="width: 100px; overflow:auto;" size="10">
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
    <option>some long text to make it scroll</option>
</select>

它可以完美地在Chrome中运行

最佳答案

div{
 overflow-x:auto;
 overflow-y:auto;
 }

<div style="width:140px;">
    <select name="selectbox" size="5"  id="selectbox" >
        <option value="1">one two three four five six seven eight</option>
        <option value="2">seven eight</option>
        <option value="3">nine ten</option>
        <option value="1">one two three four five six</option>
        <option value="2">seven eight</option>
        <option value="3">nine ten</option>
        <option value="1">one two three four five six</option>
        <option value="2">seven eight</option>
        <option value="3">nine ten</option>
        <option value="1">one two three four five six</option>
        <option value="2">seven eight</option>
        <option value="3">nine ten</option>
    </select>
</div>

这是来自Select box html horizontal scroll的内容，显示了水平滚动条。
