X-Cart 4 Advanced Filters Module – Show large filter options using a letter index

I use the advanced filter module from BCSE Engineering for X-Cart 4. This filter has less functionality than X-Carts refine filters module, but I prefer it for large stores where I usually import data from 3rd party databases.

The problem I always had with product filters is the size of each filter. The example in this video is a store with over 60K products and the filters can be really long on initial page load. So I came up with a way to show these lists more effectively by ust using javascript and some additional styling.
