title: Bootstrap 4: Multilevel Dropdown Inside Navigation
body: <p>What's the easiest way to make a multilevel dropdown in Bootstrap 4? All the examples I managed to find on SO were either too messy or not included in nav.</p>
  
  <p>I've tried just placing a dropdown inside a dropdown, but that doesn't seem like it's working. Can someone help me with this one?</p>
  
  <p>Here's the basic outline of my code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous"&gt;

  &lt;nav class="navbar navbar-toggleable-md navbar-light bg-faded"&gt;
    &lt;button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation"&gt;
      &lt;span class="navbar-toggler-icon"&gt;&lt;/span&gt;
    &lt;/button&gt;
    &lt;a class="navbar-brand" href="#"&gt;Navbar&lt;/a&gt;
    &lt;div class="collapse navbar-collapse" id="navbarNavDropdown"&gt;
      &lt;ul class="navbar-nav"&gt;
        &lt;li class="nav-item active"&gt;
          &lt;a class="nav-link" href="#"&gt;Home &lt;span class="sr-only"&gt;(current)&lt;/span&gt;&lt;/a&gt;
        &lt;/li&gt;
        &lt;li class="nav-item"&gt;
          &lt;a class="nav-link" href="#"&gt;Link 1&lt;/a&gt;
        &lt;/li&gt;
        &lt;li class="nav-item dropdown"&gt;
          &lt;a class="nav-link dropdown-toggle" href="http://example.com" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"&gt;
            Dropdown link
          &lt;/a&gt;
          &lt;div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink"&gt;
            &lt;a class="dropdown-item" href="#"&gt;Action&lt;/a&gt;
            &lt;a class="dropdown-item" href="#"&gt;Another action&lt;/a&gt;
            &lt;a class="dropdown-item" href="#"&gt;Something else here&lt;/a&gt;
          &lt;/div&gt;
        &lt;/li&gt;
      &lt;/ul&gt;
    &lt;/div&gt;
  &lt;/nav&gt;</code></pre>
