Assume that you have a dropdown list with with pre-defined values as this:

<datalist id="animallist" title="Suggestions to choose from">
  <option value="Cat">
  <option value="Cow">
  <option value="Dog">
  <option value="Horse">
  <option value="Lion">
  <option value="Pig" disabled>
  <option value="Zebra">
