我想知道如何在导航栏中的“社交媒体”类所在的位置添加下拉菜单。这是我的代码:
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavAltMarkup">
<div class="navbar-nav">
<a class="nav-item nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
<a class="nav-item nav-link" href="#">Social Media</a>
<a class="nav-item nav-link" href="#">Pricing</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</div>
</div>
</nav
答案 0 :(得分:0)
<div class="navbar-nav">
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenu2" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenu2">
<a class="nav-item nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
<a class="nav-item nav-link" href="#">Social Media</a>
<a class="nav-item nav-link" href="#">Pricing</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</div>
</div>
</div>
您必须做几件事-将商品包装在2个div标签中。一种是与类下拉菜单。此按钮包含您单击以显示实际下拉菜单的按钮。另一个div是带有class下拉菜单的。该div包含您的项目。使用较新的引导程序,您可以使用按钮代替链接项。
