Facebook-like invitation page for my categorization service

i am working on a categorization service. I want the experience to behave similarly to Facebook's invite/tagging function

Does anyone have any experience implementing this? This includes:

• autocompleting based on list below
• if auto-complete does not turn up anything, give chance to do something else with that data

Would be super ha开发者_StackOverflow社区ppy to hear any experiences, plugins that might be useful in helping me build this out

a Quick Google reveals a lot of Informations
