title: HTML Dropdown list with user input field
body: <p>I have a dropdown list as follows..</p>
  
  <pre><code>&lt;select name="school"&gt;&lt;option value="None" selected&gt;None&lt;/option&gt;
  &lt;option value="DeSoto"&gt;DeSoto&lt;/option&gt;
  &lt;option value="Hillsboro"&gt;Hillsboro&lt;/option&gt;
  &lt;option value="Grandview"&gt;Grandview&lt;/option&gt;
  &lt;option value="Festus"&gt;Festus&lt;/option&gt;
  &lt;option value="R-7"&gt;R-7&lt;/option&gt;
  &lt;option value="Home-Schooled"&gt;Home-Schooled&lt;/option&gt;
  </code></pre>
  
  <p>If the contact being entered in the database happens to live in a school district not listed in the dropdown list, the data entry person would have to add a school to the database.  How can I add a selection to the end of the list that would allow the end user to enter a school name.</p>
  
  <p>I can handle the PHP code to process the entry, I just need some ideas on how to accomplish either turning the dropdown list into a user input field, or some other solution.  Thanks for the help!</p>
