Ajax Checkboxes Products Filter by Extra Fields Values

Unique filter by extra fields values to help store customers with searching or filtering products. The contribution is similar to our "Advanced Ajax Search for Oscommerce with Extra Fields" but customers are able to choose more then one value for one extra field.

Filter can be used for any Oscommerce based stores (MS *, CREloaded, OscMax, WAI etc) with installed Extra fields contribution.
