将常规菜单转换为引导下拉菜单?

Question

我希望更改我的导航栏以具有下拉选项，但是如果不完全破坏我的代码和引导的响应能力，我就无法做到这一点。当我更改代码并且 css 完全被毁掉时，调整大小不起作用。 这是我的代码：

<header>
<div class="container">
<div class="logo">
<a href="index.html"><img src="assets/img/resultheap-logo.png" alt="" /></a>
</div>
<div class="menu">
<ul>
<li><a href="about.html">About</a></li>
<li><a href="services.html">Services</a></li>
<li><a href="Blog/index.html">Blog</a></li>
<li><a href="faq.html">FAQ</a></li>
<li><a href="contact-form/index.html">Contact</a></li>
</ul>
</div>
<div class="mobile-menu"><i class="fa fa-bars"></i></div>
</div>
</header>

Answer 1

Bootstrap 文档显示了一个带有下拉项的菜单示例：

<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown link
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
</ul>
</div>
</nav>

你试过类似的东西吗？
