任何帮助。感谢。

Answer 1

您已为模态提供tabindex="-1"。因为这个输入没有得到关注。从代码中删除tabindex它应该可以工作。

您的代码中还存在以下问题

您已经多次将HTML包含在bootstrap和select2 js文件中。仅包括一次。
在包含bootstrap js文件之前包含您的jquery文件。
您的HTML页面多次使用categoryID。 ID必须是唯一的。

Answer 2

这对我有用

    <script>
        $('#mySelect2').select2({
            dropdownParent: $('#myModal')
        });
    </script>
