[login to view URL] I have master categories, Beds, Mattresses etc. each having a unique set of sub categories. I need the plugin to provide the exact filter functionality as seen here, [login to view URL] Basic Functionality Requirements *************************** Each master category will have its own unique set of subcategories. When the product .xls spread sheet is uploaded the products must automatically filter into the predefined categories and unique sub categories for that category. The faceted search plugin must not display any subcategory if no products have been uploaded into those subcategories. Only populated subcategories must be displayed when a main category is selected from the homepage. The faceted search must have a reset button for each subcategory allowing the customer to step backwards or clear the search at any time. The faceted search plugin must be able to automatically update itself, for example if i decide to add new products which require NEW MASTER CATEGORIES and sub categories, or if I decide to delete old categories, sub categories via the admin area of the widget then the widget must identify these changes and refresh itself accordingly.
