Your shop contains huge number of products and this could be difficult for your customers to reach their best fit or desired product. This BigCommerce Add-on will help solve this problem for your customers. This add-on can apply product filters upto 4 levels of categories.
The best example for this add-on is vehicle parts shops. Customers often find it difficult to search for their desired part. Our add-on will help solve this problem by adding Make/Model/Year drop downs for searching.
You can also see extended 5 level category filter live implementation here.
