Unfortunately i do not have this as a standalone module. I can tell you that we’re using jquery and jquery UI and without those libraries it will be impossible for you. You will probably do better though to pull the code out from what is generated rather than grabbing from the PHP file.
Hey there RockyS, I’m fairly certain someone answered this question in the gocart forums already. I don’t recall the specifics simply because it can be rather difficult to keep track of all the various posts in there. GoCart forums are at http://gocartdv.com/community
