我正在尝试复制您在此图片中可以看到的内容。
我希望能够在框上方输入文本字段,或者直接点击该选项。
最好的方法是什么?是否存在任何相关的引导程序?

Select2 http://select2.github.io可能比选择更好,更活跃。
看到这个比较: http://sitepoint.com/jquery-select-box-components-chosen-vs-select2
我去了Select2(几个月前)因为Chosen在通过IME http://github.com/harvesthq/chosen/issues/2663使用中文字符时遇到了问题。它很有用。

这对我们大多数人都有效。 Hemanth Palle 给出的答案是最简单的方法,它对我有用,并且不需要JS代码。 我发现的唯一问题是,根据W3Schools的说法,Internet Explorer 9和更早版本或Safari不支持The datalist tag。
