title: How to blur the div element?
body: <p>I have a dropdown menu inside a DIV.</p>
  
  <p>I want the dropdown to be hide when user click anywhere else.</p>
  
  <pre><code>$('div').blur(function() { $(this).hide(); }
  </code></pre>
  
  <p>is not working.</p>
  
  <p>I know .blur works only with <code>&lt;a&gt;</code> but in this case what is the simplest solution?</p>
