Outlook 2007/Gmail Style Textbox “To…” | Autocomplete AJAX

[Damo]

I just like a to create a textbox with same behaviour as Outlook 2007/GMail, when you create a new mail, there is "To.." textboxt, when you type something,

• it provide you a list of person name/email with image, when you select from the list, it will be underline and no way to edit it, except to delete it and enter an new.
• then when you use a seperator like semicolon ";" when you type again it also provide you a list of person name/email

Can someone point me where or how can i accomplish something like that. I hope this is available on AJAX or any form.Thank you very much.
