On edit: it has .innercontent{display: none;} and the content loads, but is only seen after the user clicks on the letter B for example to see the products that start with "B". Will goog see this as cheating?

No - it's a very standard show/hide div script. When ordinary (and even explicitly called for) user action displays the content, you're fine.
