        To create a <strong>dropdown menu</strong>, you will need <strong>4</strong> elements:
      </p>
      <ul>
        <li>
          <code>navbar-item</code> with the <code>has-dropdown</code> modifier
        </li>
        <li>
          <code>navbar-link</code> which contains the dropdown arrow
        </li>
        <li>
          <code>navbar-dropdown</code> which can contain instances of <code>navbar-item</code> and <code>navbar-divider</code>
        </li>
      </ul>
    </div>

    <div class="columns">
      <div class="column">
        <div class="example is-paddingless">
          {{ navbar_dropdown_example }}
        </div>
      </div>

      <div class="column">
        {% highlight html %}{{ navbar_dropdown_example }}{% endhighlight %}
      </div>
    </div>

    <h4 class="title is-4">
      Show/hide the dropdown with either <strong>CSS</strong> or <strong>JavaScript</strong>
    </h4>

    <div class="content">
      <p>
        The <code>navbar-dropdown</code> is visible on touch devices {% include bp/touch.html %} but hidden on desktop {% include bp/desktop.html %}. <em>How</em> the dropdown is displayed on desktop depends on the parent's class.
      </p>
      <p>
        The <code>navbar-item</code> with the <code>has-dropdown</code> modifier, has <strong>2 additional modifiers</strong>
      </p>
      <ul>
        <li>
          <code>is-hoverable</code>: the dropdown will show up when <strong>hovering</strong> the parent <code>navbar-item</code>
        </li>
        <li>
          <code>is-active</code>: the dropdown will show up <strong>all the time</strong>
        </li>
      </ul>
    </div>

    <div class="message is-success">
      <p class="message-body">
        While the CSS <code>:hover</code> implementation works perfectly, the <code>is-active</code> class is available for users who want to control the display of the dropdown with <strong>JavaScript</strong>.

    <div class="columns">
      <div class="column">
        <div class="example is-paddingless">

    <div class="content">

        By default, the <code>navbar-dropdown</code> has:

      <ul>
        <li>
          a grey <code>border-top</code>
        </li>

    <div class="content">
      <p>
        When having a <a href="#transparent-navbar">transparent navbar</a>, it is preferable to use the boxed version of the dropdown, by using the <code>is-boxed</code> modifier.

          the grey border is <strong>removed</strong>
