[PHP] Drop down Menu

[The New Source]

Hi, I need to do a drop down menu that loads the contents from a msql
database.
Like this: I need a select that has the name of every salesman of a
certain department, and this info is dynamic and is recorded in a
database (MySql). 
So what would the select have to be like?
Also the load value is obvious diferent from the value that is sent from
the form when the submit button is pressed, this value would be another
column in the same table of the name.
Thanks,
Rodrigo
