如何为select2 drop元素添加特定的类? [英] How to add a specific class to select2 drop element?

问题描述

我通过CSS使用常规类和ID自定义了select2.

I have select2 customized via css with its general classes and ids.

现在，我正在尝试自定义将提供给select2的特定类，然后将其应用于CSS.

Now, I'm trying to customize a specific class that will be provided to select2 and then apply in css to it.

我的问题:不是说每句话而是掉在主体上的那一滴(类为 select2-drop 的div)，如何我可以访问那个人吗?

My issue: is NOT the select per say but the drop of it ( the div with the class select2-drop ) that is appended to the body, how can i access that one?

我已经尝试过:

$(".element").select2({
   minimumResultsForSearch: -1,
   containerCssClass : "error"
  }
);

，但是类error没有继承到该div.

but the class error is not inherited to that div.

更新: 这是我正在谈论的图形元素(选项区域):

UPDATE: This is the graphic element i'm talking about ( the options area ):

这是被检查对象中想要添加该特定类的代码，因此我可以在CSS中使用它:

And this is the code in the inspected where i want to add that specific class, so i can play with it in CSS:

更新: jsfiddle

推荐答案

您可以使用dropdownCssClass将类添加到select2-drop.我阅读了整个插件以了解发生了什么.最后，我找到了这个选项.

You can use dropdownCssClass for adding class to the select2-drop. I read whole plugin to understand what is going on. Finally, I found that option.

 $(".jSelectbox").select2({
     containerCssClass: "error",
     dropdownCssClass: "test"
 });

$(".jSelectbox").select2({
  containerCssClass: "error",
  dropdownCssClass: "test"
});
