react-route-dom 实现简单的嵌套路由

最终效果
点击 to test1

点击to test2  =>  to test21

点击to test2  =>  to test22

代码如下
 

          path: "page",
          element: <父组件 />,
          children: [
            { path: "test1", element: <Test1 /> },
            {
              path: "test2",
              element: <Test2 />,
              children: [
                { path: "test21", element: <Test21 /> },
                { path: "test22", element: <Test22 /> },
              ],
            },
          ],

父组件如下 

   import { NavLink, Outlet } from "react-router-dom";    

         <div>
          I am 父组件
          <div>

            <NavLink to="/en/page/test2"> to test2</NavLink>
          </div>
