title: Editable combobox only in PHP or HTML
body: <p>Here is my table:</p>
  
  <pre><code>&lt;/td&gt; 
  &lt;/tr&gt;
  &lt;tr&gt; 
  &lt;td&gt;Test System: &lt;/td&gt;
  &lt;td&gt;&lt;select name="TestSystem"&gt;
  &lt;?php 
  $result = mysql_query("select name from test_system");   
  while($row = mysql_fetch_array($result))
  {
  echo '&lt;option value="" selected&gt; &lt;/option&gt;';
  echo '&lt;option value="' .$row['name'] .'"&gt;'.$row['name'].'&lt;/option&gt;';
  }
  ?&gt;
  &lt;/select&gt;       
  &lt;/td&gt; 
  </code></pre>
  
  <p>but I want it to be editable. It means, for example that the user can write first letter(for example "A"), and he can see all the options starting with the letter "A".
  Is there anyway to do this without any frameworks/JavaScript? Only in PHP or HTML?</p>
