title: Zurb Foundation 5 toggle-topbar not working
body: <p>Just switched my rails project to test Zurb Foundation 5 and now the toggle-topbar menu is not working.</p>
  
  <p>When the viewport is small, the top bar menu items disappear and the menu icon is displayed as before, but when I click on the menu icon nothing occurs.</p>
  
  <p>I have the following code to display a top-bar menu.</p>
  
  <pre><code>&lt;nav class="top-bar"&gt;
    &lt;ul class="title-area"&gt;
      &lt;li class="name"&gt;&lt;/li&gt;
      &lt;li class="toggle-topbar menu-icon"&gt;
        &lt;a&gt;{href: "#"}
          &lt;span&gt;Menú&lt;/span&gt;&lt;/a&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
    &lt;section class="top-bar-section"&gt;
      &lt;ul class="left"&gt;
        &lt;li&gt;
          &lt;a class="i fi-home"&gt;{href: "/ui/home"}
            &amp;nbsp;Inicio&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;
          &lt;a&gt;{href: "/ui/wine_reviews"} Críticas de Vinos&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;
          &lt;a&gt;{href: "/ui/wine_tastings"} Catas y Maridajes&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;
          &lt;a&gt;{href: "/ui/blogs"} Noticias&lt;/a&gt;&lt;/li&gt;
      &lt;/ul&gt;
      &lt;ul class="right"&gt;
        &lt;li&gt;
          &lt;a&gt;{href: "#"}
            &lt;i class="fi-lock"&gt;&lt;/i&gt;
            &amp;nbsp;Club TastaVi&lt;/a&gt;&lt;/li&gt;
      &lt;/ul&gt;
    &lt;/section&gt;
  &lt;/nav&gt;
  </code></pre>
  
  <p>It's a top-bar menu contained in my grid.</p>
