token input

 token input  is a style of form element which allows the user to type free-form text (or select a term via autocomplete), and then turns each term into a new inline element, usually outlining the term and showing a little "x" which allows the user to delete the term by clicking it.

uses Red Wind on kylewm.com and its creation UI has an input for person-tags which implements token input. Kyle demonstrated this UI at the IndieWebCamp SF introductory demos.
