title: Google+ style autocomplete + dropdown jQuery plugin
body: <p>I am looking for a jQuery plugin that behaves like the Google+ autocomplete + dropdown. In G+, I can enter a person's name and it'll look in my circles and show me a list of matches, or I can click the dropdown arrow at the end of the input box to get a list of all possible names that I can select from. I was able to find plugins that do the autocomplete, but nothing that mixes that with a dropdown functionality to show you all possible names. Any ideas?</p>
