I've seen this question asked a lot on here, but my code seems to be correct. My data-target id matches the id of the collapse div. not sure why then menu isn't opening when I click on the hamburger icon.

<nav class="navbar navbar-expand-sm bg-dark navbar-dark fixed-top">
    <div class="container">
      <a href="index.html" class="navbar-brand">LoopLab</a>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCollapse">
        <span class="navbar-toggler-icon"></span>
      </button>
      <div id="navbarCollapse" class="collapse navbar-collapse">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item">
            <a href="#home" class="nav-link">Home</a>
          </li>
          <li class="nav-item">
            <a href="#explore-head-section" class="nav-link">Explore</a>
          </li>
          <li class="nav-item">
            <a href="#create-head-section" class="nav-link">Create</a>
          </li>
          <li class="nav-item">
            <a href="#share-head-section" class="nav-link">Share</a>
          </li>
        </ul>
      </div>
    </div>
  </nav>

当我使用你的代码和Bootstrap 4模板时，它看起来工作正常。2确保你正确地加载了Bootstrap的JS和CSS。3使用小窗口可以看到汉堡菜单图标。

对于项目Angular：
请确保angular.json文件中包含bootstrap.css、jquery.js和bootstrap.js文件。
例如：

"styles": [
          "node_modules/bootstrap/dist/css/bootstrap.css",
          "src/styles.scss"
        ],
"scripts": [
          "node_modules/jquery/dist/jquery.min.js",
          "node_modules/bootstrap/dist/js/bootstrap.js"
        ]
