CB Package Builder - Including package search on packages display page

I'm using CB Package Builder in a very similar display fashion as the "Downloads" link on the Joomlapolis site.

On this page...
www.joomlapolis.com/downloads
How is the search included at the top of the page?

I'd like to do the same thing on my downloads page. www.alphadataiq.com/index.php/adiq-downloads

Thanks,
Jim
