title: Rail3 - Smart way to Display Menu & add an Active Style Class?
body: <p>Given a Rails 3 App with a menu like: </p>
  
  <pre><code>&lt;ul&gt;
   &lt;li&gt;Home&lt;/li&gt;
   &lt;li&gt;Books&lt;/li&gt;
   &lt;li&gt;Pages&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>What is a smart way in Rails to have the app know the breadcrumb,,, or when to make one of the LIs show as:</p>
  
  <pre><code> &lt;li class="active"&gt;Books&lt;/li&gt;
  </code></pre>
  
  <p>thx</p>
