Bootstrap 树视图：树没有显示

Question

我是树视图的新手，我试图显示一个基本的树，但它不起作用，我不知道我在哪里犯了错误。

我制作的 test.html 遵循与我的 basic.html 相同的结构（我为您省去了导航栏、警报等代码）。我在 functions.js 中还有其他 js 函数可以正常工作。

test.html:

{% csrf_token %}
{% load groupfilter %}
{% load staticfiles %}
<!DOCTYPE html>
<html lang="en">
   <head>
       <meta name="viewport" content="width=device-width, initial-scale=1" charset="utf-8">
       <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
       <link rel="stylesheet" href="{% static 'bootstrap-treeview.min.css' %}">
       <script src="{% static 'bootstrap-treeview.min.js' %}"></script>
       <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

    <title>Test</title>
   </head>
        <body>
            <div class="container">
                <div id="tree"></div>
            </div>
            <!-- JavaScript functions -->
            <script src="{% static 'functions.js' %}"></script>
        </body>
</html>

functions.js 的摘录：

$(function(){
    var mytree = [
        {
            text: "Parent 1",
            nodes: [
                {
                    text: "Child 1",
                    nodes: [
                        {
                            text: "Grandchild 1"
                        },
                        {
                            text: "Grandchild 2"
                        }
                    ]
                },
                {
                    text: "Child 2"
                }
            ]
        },
        {
            text: "Parent 2"
        }
    ];

    $('#tree').treeview({data: mytree});
});

你能分享你正在关注的示例 link 吗？

您似乎正在导入 Twitter Bootstrap 4.3.1

但据我所知，Offical Bootstrap 仍然没有在他们的文档中提供 TreeView。
