Menu On Textfield And Its Id On Another ?

Have you ever used google? If we typed somewords into it, then google would eventually appeared the suggestion words.... I wonder, if we use jquery or javascript manually, how to create the dropdown menu on that textfield? I mean, ya, how to create the suggestion list menu on that textfield....? since the plugin that jquery ~autocomplete has worked well but, I need some adjustment that not just receiving 1 type of values.

Let say;

If we have these table on mysql;

Code:

Then... so suppose I want to do ajax request that retrieves names & id(s) and extract it into two different elements;

1) textfield suggestion menu (name).

2) another html element (id).
