title: Default selection in bootstrap dropdown
body: <p>I am using a bootstrap dropdown, and need to have the first option as default. The following doesn't work. </p>
  
  <pre><code>&lt;div class="dropdown"&gt;
  &lt;button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true"&gt;
      CHOOSE FEATURE
      &lt;span class="caret"&gt;&lt;/span&gt;
  &lt;/button&gt;
  
  &lt;ul class="dropdown-menu" aria-labelledby="dropdownMenu1"&gt;
      &lt;li selected="selected"&gt;&lt;a&gt;Feature 1&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a&gt;Feature 2&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a&gt;Feature 3&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a&gt;Feature 4&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a&gt;Feature 5&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a&gt;Feature 6&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
