Question

Bootstrap4中的折叠导航栏出现问题。

<nav class="navbar navbar-toggleable-md navbar-inverse fixed-top bg-inverse">
      <button class="navbar-toggler navbar-toggler-right collapsed" type="button" data-toggle="collapse" data-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>
      <a class="  navbar-brand" href="#myCarousel">
        <img src="image/logo.svg" height="50">
      </a>
      <div class="collapse navbar-collapse" id="navbarCollapse">
        <ul class="navbar-nav nav mr-auto">
           <li class="nav-item">
            <a class="nav-link" href="#2"  data-toggle="collapse" data-target=".navbar-collapse.show">Home</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#3"  data-toggle="collapse" data-target=".navbar-collapse.show">About</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#4"  data-toggle="collapse" data-target=".navbar-collapse.show">Contact</a>
          </li>
        </ul>

      </div>
    </nav>

当然，我已经为其他元素添加了正确的ID，例如：

<div class="container marketing" id="2">

菜单不起作用。当我点击导航栏的元素时，菜单关闭但不会移动到右侧站点。

删除折叠的属性时：

data-toggle="collapse" data-target=".navbar-collapse.show"

菜单不会在点击时关闭，而是移动到正确的网站。

谢谢:)
