title: jQuery unselect dropdown menu
body: <p>I have a dropdown menu for states. The first option is 'Please select state' and its value is 0 but a state is always selected it as the user picks a state from a previous page and it somehow gets state and selects it. I want it to be at value 0.</p>
  
  <p>I have this code....</p>
  
  <pre><code>$('#shipstate option').attr('selected', '');
  </code></pre>
  
  <p>but this sets all my options to selected.</p>
  
  <p>What Am I doing wrong?</p>
