Hello! The site works under the control of cms joomla 1.5 + virtuemart 1.1.6, added a filter on the parameters of the product, for example http://www.kover2.mnogomesta.ru/component/virtuemart/22- , tell me how you can prohibit the button "Pick up" If the filter has "default" values (i.e., any length, any width, any shape, any price, all manufacturers)? It seems like an Ajax is necessary, but I would not like to fasten the Aayakstut. Can there be any solution for it easier? Sincerely.
