On OSUTrade, when the user starts typing on the search input, a list of relevant suggestions will show up for the user to select, a la Google Suggest (or any other modern search engine). This is possible through the use of the undocument Google Suggest API and jQueryUI's autocomplete widget (although you can use pretty much any other JavaScript libraries out there, or even write you own code to accomplish the same).

This past week I have been working on refactoring the backend/behind-the-scene code for OSUTrade and moving away from Google App Engine's webapp framework. While I was refactoring the client-side of the code, I thought that there might be people who are interested in having the auto-suggest functionality on their site as well, so I wrote a jQuery plugin from the code that I had. I think people with shopping sites will be most interested in using this with the holiday season coming up (the Suggest API has an option to list only suggestions from Google Products).

Check it out on Google Code if you are interested and your feedbacks are welcomed, as always.
