我需要找到一个具有残疾成分的多功能箱子。 我想盒子照样:
所有人
-
备选案文1
备选案文2
“或”无法选择。 迄今为止,我的法典非常简单:
<select multiple size="4" >
<option value="0">All</option>
<option value="1">----or----</option>
<option value="2">备选案文1</option>
<option value="3">备选案文2</option>
</select>
但截至目前,我一直无法得到残疾或无法当选。 我看一遍,我不敢肯定会有一个可予以解脱的超文本属性,但我确实不相信,我也不相信这是提出这一选择的最佳途径。 你们能够提供的任何帮助都受到高度赞赏。
