因此，我尝试在用户单击链接时自动关闭移动设备上的引导导航栏，并遇到以下链接：

单击链接时自动关闭导航栏（响应模式）

但是，如果导航栏有下拉菜单，那么上面的示例似乎会崩溃......

所以我的问题是，当 bootstrap 4.3.x 导航栏中有下拉菜单时，我将如何实现这一点？

诗。我还尝试了下面提到的链接，但无济于事：

这通过添加到span标签对我有用。data-bs-target="#navbarSupportedContent" data-bs-toggle="collapse"在锚标签（Nav-Link）内部放置span标签，你可以在代码中看到它

     <nav class="navbar navbar-expand-lg navbar-light bg-light">
                <div class="container">
                    <a class="navbar-brand" href="/">Navbar</a>
                    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                        <span class="navbar-toggler-icon"></span>
                    </button>
                    <div class="collapse navbar-collapse" id="navbarSupportedContent">
                        <ul class="navbar-nav me-auto">
                            <li class="nav-item active">
                                <a class="nav-link" href="/"><span data-bs-target="#navbarSupportedContent" data-bs-toggle="collapse">Home</span></a>
                            </li>
                            <li class="nav-item">
                                <a class="nav-link" href="#About"><span data-bs-target="#navbarSupportedContent" data-bs-toggle="collapse">About</span></a>
                            </li>
                            <li class="nav-item">
                                <a class="nav-link" href="#Contact"><span data-bs-target="#navbarSupportedContent" data-bs-toggle="collapse">Contact</span></a>
                            </li>

                        </ul>
                    </div>
                </div>
