Allow input not listed

It seems (unless I missed it) that selectivity restricts your input to what's available, just like normal select does. But sometimes it's nice to have the items be just suggestions, like HTML5 input with datalist.

I was also looking for a solution to this, so that is not available at all ? Using selectivity for a tag system and adding custom tags is necessary for me
