Autocomplete textbox? Different datasources?

Hi, 

I am currently developing a stock rental control system utilizing XUL as
the GUI.

What I require is a widget that operates like the Windows Forms
drop-down list box which will automatically select the best matching
item as the user is typing. This functionality could be replicated using
the 'autocomplete' textbox in XUL however, there only seems to be 2
available datasources (history and form-history).

I have tried using a menulist however, typing a key when the list is
displayed only causes it to match on the first character.

Is there a way to add a custom datasource to a XUL autocomplete textbox?

Thanks for your help,

Wayne
