Hi Phil,
On your demo, under the left panel section "Categories", rollover the main items. As you go down the list of main items, each of the second level subcategories fly out. However, there is no indication of whether there is a third level subcategory. This would be helpful for the shopper to see.

I give three possibilities on how to show this:
1. As you rollover the main category, all subcategories automatically fly out.
2. As you rollover the main cat, a red (or different color) > symbol appears only on the second level cats that have a third level cat.

Otherwise the shopper has no way of knowing if there are products in the third level, and most will assume not.
