The closest we have now is datalist[1], which acts as a data source that you can attach to a text input to give it autocomplete. Unfortunately, it isn't nearly as fully-featured as it could be, possibly because no one uses it so there's no incentive to make it better (although Chrome's implementation has gotten markedly better over the past two years or so, mostly by fixing blatant bugs).
