Autocompleter - complete form from autocomplete field

Autocompleter - complete form from autocomplete field

Using the Autocompleter, is it possible to fill in multiple fields from the data returned?  I am looking for a tool to make this possible with ease.
 
Example:
 
Employee field:  user selects an employee from a field using this autocomplete.  Once the selection is made I need 3 other fields completed from this selection.  Is this possible?  If so, would this data be passed to the autocomplete or from a function called after autocomplete success?  Would love an example if possible.
