html - 如何解决下拉菜单错误且不显示？

问题描述

这里我用的是引导模板，但是下拉菜单打不开……我还是个初学者，不明白怎么解决，我的问题有什么解决办法？

<!-- Navigation-->
    <nav class="navbar navbar-expand-lg navbar-light bg-light">
        <div class="container px-4 px-lg-5">
            <a class="navbar-brand" href="#!">MITRA JAYA FURNITURE</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 mb-2 mb-lg-0 ms-lg-4">
                    <li class="nav-item"><a class="nav-link active" aria-current="page" href="#!">Home</a></li>
                    <li class="nav-item"><a class="nav-link" href="#!">Tentang Kami</a></li>
                    <li class="nav-item dropdown">
                        <a class="nav-link dropdown-toggle" id="navbarDropdown" href="#!" role="button" data-bs-toggle="dropdown" aria-expanded="false">Kategori</a>
                        <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
                            <li><a class="dropdown-item" href="#!">All Products</a></li>
                            <li><hr class="dropdown-divider" /></li>
                            <li><a class="dropdown-item" href="#!">Popular Items</a></li>
                            <li><a class="dropdown-item" href="#!">New Arrivals</a></li>
                        </ul>
                    </li>
                    <li class="nav-item"><a class="nav-link" href="#!">Tentang Kami</a></li>
                </ul>
                <form class="d-flex">
                    <button class="btn btn-outline-dark" type="submit">
                        <i class="bi-cart-fill me-1"></i>
                        Cart
                        <span class="badge bg-dark text-white ms-1 rounded-pill">0</span>
                    </button>
                </form>
                 <ul class="navbar-nav me-auto mb-2 mb-lg-0 ms-lg-4">
                 <li class="nav-item"><a class="nav-link" href="login.php">Login</a></li>
             </ul>
            </div>
        </div>
    </nav>

为什么不显示下拉框？您可以在这里查看更多带有预览的代码https://jsfiddle.net/laelza/yq68dok5/1/

请告诉我我错在哪里。太感谢了。:)

解决方案

好像您忘记添加引导程序的 JS 代码：

这是工作示例：https ://jsfiddle.net/8e3y6Lfv/
