Hello, I have a fragrance shop on zencart and I would to categorize my subcategory in alphabetical order?
I mean they already are, but I would like it so that the customers can select the subcategory (or the product name) by the alphabet.

Here's an example http://www.fragrancenet.com/department/womens-perfume

on the left hand side, customers can click on the alphabet to find the product.

Please help how I can get this feature on my website.

Thank you.
