The datalist element is pretty cool. You can make dropdown inputs that are still editable realy easy. Came in handy today.

<label>
	Choose a flavor:
	<input list="ice-cream-flavors" name="ice-cream-choice" />
</label>

<datalist id="ice-cream-flavors">
  <option value="Chocolate"></option>
  <option value="Coconut"></option>
  <option value="Mint"></option>
  <option value="Strawberry"></option>
  <option value="Vanilla"></option>
</datalist>
