Answer 1

<select>
     <option value="" style="display:none;"></option>
     <option value="0">aaaa</option>
     <option value="1">bbbb</option>
  </select>

Answer 2

Simply using

<option value="" selected disabled>Please select an option...</option>

will work anywhere without script and allow you to instruct the user at the same time.
