Autocomplete with multiple value fields

Hi I am wondering how can I set multiple value fields for the auto complete component.

What I want to do is:

Once that the user has selected the autocomplete value, let’s say email, I would like to insert this info into a database, the problem is that I can only set one value (e.g. email). but I would like to add email, first name, last name and user id.

How can I do this?

Thanks

Juan
