How to Use select2.js
提问by petarap
I want to add a form field which can auto fill text & can take multiple tabs(similar to fb). I found select2.js helps me do it, But i am having problems in using it when i set multiple attribute to true. if i add multiple: true, the page dispalys it as a normal select.
我想添加一个可以自动填充文本的表单域，并且可以使用多个选项卡（类似于 fb）。我发现 select2.js 可以帮助我做到这一点，但是当我将多个属性设置为 true 时，我在使用它时遇到了问题。如果我添加多个：true，页面将其显示为正常选择。
I find documentation on select2 page confusing.
我发现 select2 页面上的文档令人困惑。

Add the attribute "multiple", and a width as well, only in the markup.
仅在标记中添加属性“multiple”和宽度。
<select multiple id="e1" style="width:300px">
and js as this:
和 js 如下：
$(document).ready(function() {
$("#e1").select2();
});

You can override the class specific for select2.js:
您可以覆盖特定于 select2.js 的类：
.select2-container-multi .select2-choices {
width: 150px;
}
It should work.
它应该工作。
