title: Select option tag with "Please select" message
body: <p>I want a dropdown list with say the following options. And I want a please select info when no option is selected. I have implemented it through the code below. And the form is submitted when one option is selected. But the problem is when I navigate back to the page, and select the first option i.e --Please Select--, my form gets submitted for that option too. Is there any solution for it, so that I could just display a --please select-- option when no option is selected and not submit the form for that particulat --please select-- option.??</p>
  
  <pre><code>&lt;select onchange="this.form.submit()"&gt;
      &lt;option&gt;--Please Select --&lt;/option&gt;
      &lt;option value="volvo"&gt;Volvo&lt;/option&gt;
      &lt;option value="saab"&gt;Saab&lt;/option&gt;
      &lt;option value="mercedes"&gt;Mercedes&lt;/option&gt;
      &lt;option value="audi"&gt;Audi&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
