If what you are looking for is the autocomplete type thing then you are probably wanting a combo box.
The simplest form of that is probably the html5 list attribute:

But there are also some jquery options:

I am not sure that there are any ready made controls that will let you add an item by typing it into the combobox, most just do the sutocomplete type thing allowing you to search the list by typing something in and finding it in the list.
I would think that someone had to come up with one at some poiint though because it really wouldn't be that difficult to figure out (famous last words).
