我有两个下拉选择框，导致两个职业的详细信息并排显示在表格的列中。为了便于使用和修改，代码被编辑了下来，去掉了许多实际的选项。它目前的工作很好，除了将有超过300个值可供选择，这是很多滚动。因此，我想使下拉框可搜索。我遇到的两个最好的选项是Select2和Chosen。
我似乎不能得到选择2或选择工作(即不使下拉框可搜索)。我两种都试过了，一定是哪里做错了。如果我从头开始一个jsfiddle，我可以让它们工作，但我似乎无法将其添加到我当前的代码中。我想我只是不确定如何将其集成到我当前的代码中。我已经放弃了展示我开始使用的代码的尝试。在哪里/如何我应该添加Select2到我的两个现有的下拉菜单的任何帮助将不胜感激。
这是我的jsfield
