just put an a href around the label and put a ?itemid=xxx type of thing it, that calls the script and shows the page with the correct item selected.
When creating the list just put the items number into the href. Typically I use phplib template so i have the html all sitting there statically with a {ITEMID} sitting in the places I need it and I only have to set up the value once.
if you want to use the template for this type of application let me know (via this forum) and I'll send a "good" version as the one I downloaded (ages ago admittedly) was buggy for the block row functionalilty.
