我对HTML中的选择有疑问。 现在我有两个值下拉列表。 例如：
<select name="healthy" id="healthy">
<optgroup="fruit"></optgroup>
<option value="apple">apple</option>
<option value="pineapple">pineapple</option>
<optgroup="vegetables"></optgroup>
<option value="carrots">carrots</option>
<option value="tomato">Tomato</option>
</select>
现在我不想在1列中显示这些组，而是希望在不同的列中显示它们。这可能，而不是更改代码吗？
修改 在得到相同的答案两次后，这是不可能的，我会稍微改变这个问题。 是否可以制作自己的表单元素？例如，在Actionscript，VB.Net，asp.Net中，可以创建自己的元素。我知道你可以用CSS改变布局，但那不是解决方案。 所以我想说的是，我只想基于select。

我想我找到了答案。 我的HTML代码：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<link href="select.css" rel="stylesheet" type="text/css" />
</head>
<body>
<select name="sel" id="sel">
<optgroup label="group1">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</optgroup>
<optgroup label="group2">
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
</optgroup>
</select>
</body>
</html>
我的css代码
@charset "utf-8";
/* CSS Document */
#sel{
background-color:#FF0;
width:40px;
}
#sel optgroup{
background-color:#CFF;
display:inline-table;
width:20px;
}
- 编辑 - 问题：IE和Chrome无法识别内联表。所以它不适用于那些浏览器。

据我所知，这是不可能的。但你可以在彼此旁边制作两个选择框！
