[web2py] drop down list as auto-complete

[max]

In my dependancy tables I have thousands of entries.
e.g.

frg.define_table('group',
   Field('name','string'),
)
 
frg.define_table('kundenstamm',
Field('a20',frg.group),
)

frg.kundenstamm.a20.requires = IS_IN_DB(frg, frg.group.id, '%(id)s , 
%(name)s',zero=T('Choose'))


I  have thousands of values in group.
So in my SQLFORM in kundenstamm , I need a auto-complete instead of a drop 
down.
is it possible?
