我使用选定的库，我的下拉菜单显示为这样，我该如何解决这个问题。 谢谢。 dropdownCSS - 我该怎么做才能解决这个问题？

就像你可以在图片上看到的值的列表出现在另一个元素下，而不是在第一个计划，所以值的列表是不可见的。 我应该在CSS中更改以解决该问题。

这里是CSS：

嗨， 正如你所看到的图片，下拉列表是不可见的，当我点击显示列表，它出现在下面。对不起，如果不明确。 – 2015-02-11 16:34:35

@ user3515709你提供了CSS很好，但是从上面我们看不到哪个元素有什么CSS代码。你有一个工作的例子吗？或者，也许你可以添加它的HTML/PHP部分。同样，我可以从CSS注释中看到您已经从这里下载了脚本：[http://harvesthq.github.io/chosen/](http://harvesthq.github.io/chosen/）也许你应该阅读它再次，[有明确的指示]（http://harvesthq.github.io/chosen/）如何使用它。 – balintpekker 2015-02-12 06:30:58

元素示出在顶部或下方彼此可以在CSS用z-index属性进行管理。您可以为顶部的元素应用-1。

嗨，我可以看到在CSS中为选择下拉和选择搜索类定义了z-index，这些值看起来相当高，但是没有为选择结果定义z-index，其中包含项名单，可能是什么原因？ – 2015-02-13 15:06:00

我不能说原因，但你可以添加相同的值（1010）到搜索部分关闭CSS例如通过浏览器上的Firefox开发工具，你会立即看到它是如何帮助或不？ – mico 2015-02-13 21:49:46

开发工具使您可以改变CSS来测试网站如何使用不同的设置，而无需触摸实际的源代码。只要玩CSS设置来找到正确的组合，然后你可以添加到实际的CSS文件，如果你有访问。欲了解更多信息：https：//developer.mozilla.org/en-US/docs/Tools/Web_Console – mico 2015-02-13 21:55:31

将下拉带班 '选择，向上' 一个div

<div class="chosen-upward"> 
    your dropdown with class 'chosen-select' 
</div>

内添加到风格

.chosen-upward.chosen-drop{top:inherit!important; bottom:33px!important;border-bottom-right-radius:0px!important;border-bottom-left-radius:0px!important;border-top-right-radius:4px;border-top-left-radius:4px;box-shadow:none!important;}

这将使下拉出现上述的选择控制。
