title: link_to options
body: <p>So I'm trying to make this into a link_to link:</p>
  
  <pre><code>&lt;a class="dropdown-toggle" data-toggle="dropdown" href="#"&gt;Sign-In &lt;b class="caret"&gt;&lt;/b&gt;&lt;/a&gt;
  </code></pre>
  
  <p>I have this so far, but can't figure out how to handle the <code>&lt;b class="caret"&gt;&lt;/b&gt;</code>. I have tried a do block at the end of the <code>link_to</code>, but only got an error.</p>
  
  <pre><code>&lt;%= link_to "Sign-In", new_user_session_path, :class =&gt; "dropdown-toggle", :data =&gt; {:toggle=&gt;"dropdown"} %&gt;
  </code></pre>
  
  <p>I've just started learning Rails, and have searched around (including reading the RoR API docs) but have got nothing to work. Thanks for the help!</p>
