为什么附加到我的表单的 2 <select> 元素看起来与我的表单中固定的前 2 个元素不一样？
Why are the 2 <select> elements that are being appended to my form not looking the same as the first 2 fixed in my Form?
我有一个获取公司信息的 HTML 表格。
在那个表格中，我有 2 个 <select multiple> 元素（一个用于公司所在国家/地区，一个用于部门），我在这些元素上使用了 JQuery 和 Bootstrap 来为它们提供漂亮的样式和允许用户以更简单的方式选择多个选项。
问题： 当用户单击“添加公司按钮”向表单添加新的公司部分时，附加的 <select multiple> 元素未设置样式同样的方式。
区别不在前两个 select 字段之间，而是在前 2 个 select 字段和单击 'Add Company' 时添加的对之间。前两个显示的是我想要的方式（2 个矩形框，用户可以在其中单击下拉列表中的多个选项），而其他的则显示为无样式的下拉列表，您必须按 Ctrl + 单击您想要的选项 select
请注意，为了简单起见，我删除了页面的 CSS 和其他部分。同样在附加部分中，我删除了一些选项以保持在 post
的字符限制内

我的Fiddle：https://jsfiddle.net/30jwqfc5/
前两个 select 元素是 select2 的实例，后面的元素是原生 html select。在单击处理程序中点击添加公司按钮后，您需要为动态生成的 select 元素实例化 select2，
$('.mul-select').select2();

我有一个获取公司信息的 HTML 表格。
在那个表格中，我有 2 个 <select multiple> 元素（一个用于公司所在国家/地区，一个用于部门），我在这些元素上使用了 JQuery 和 Bootstrap 来为它们提供漂亮的样式和允许用户以更简单的方式选择多个选项。

我的Fiddle：https://jsfiddle.net/30jwqfc5/
前两个 select 元素是 select2 的实例，后面的元素是原生 html select。在单击处理程序中点击添加公司按钮后，您需要为动态生成的 select 元素实例化 select2，
$('.mul-select').select2();
