How to solve Dropdown Menu error and doesn't show? - html

Question

Here I use a bootstrap template, but the dropdown menu can't be opened ... I'm still a beginner and I don't understand how to fix it, what is the solution to my problem?
<!-- 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>
