我正在学习使用 Bootstrap Toggler 和 Dropdown 都没有展开，老实说我不知道我做错了什么。

这是导航栏代码（部分代码，我使用的是 Handlebars）

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo03"
      aria-controls="navbarTogglerDemo03" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand" href="#">Titleee</a>
    <div class="collapse navbar-collapse" id="navbarTogglerDemo03">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Dashboard</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Withepaper</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown"
            aria-expanded="false">
            Community
          </a>
          <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
            <li><a class="dropdown-item" href="#">Discord</a></li>
            <li><a class="dropdown-item" href="#">Telegram</a></li>
            <li><a class="dropdown-item" href="#">Twitter</a></li>
          </ul>
        </li>
      </ul>
    </div>
  </div>
</nav>

您还必须导入 bootstrap.js 文件才能使切换器和下拉菜单正常工作，
