HTML5 datalist* allows to autocomplete input elements with static content (option element).
<input list="cars"/>
<datalist id="cars">
<option value="BMW"/>
<option value="Ford"/>
<option value="Volvo"/>
</datalist>Thanks to Olives Framework, you can bind datalist options to a store and set them as you wish.
If you are interested, I put an example into my github.
*Until now, only Firefox supports this feature.
