Need to create 'TO' field in Compose New Message simillar to Compose New Message "TO" Filed of hotmail.com;  it should have auto-fill (populated from contacts), and selected Contact goes into 'TO' filed textbox alongwith remove button and edit button,
or it may be like Compose New Message 'TO'  filed of linkedin.com


Any ideas will be appreciated.
