[SOLVED] Jquery - Autocomplete Question

I'm experimenting with Jquery Autocomplete using the car file. So far jquery is working quite nicely but I'm looking to tweak the html front screen.

How do I limit the dropdown list to 20 items instead of the full file?

I have a file which contains 10000 items and I do not want to show all the items when users click the dropdown.

Sample Jquery Autocomplete - Car file

DEFINE FILE CAR
CARLIST/A180  = '<OPTION VALUE="' || MODEL || '"> ' |CAR || ' ' | MODEL;
END
TABLE FILE CAR
SUM
CARLIST
BY CAR NOPRINT
ON TABLE SAVE AS CARPICK
END
