 Descripcion: 

Spider Catalog for Joomla! is a convenient tool for organizing the products represented on your website into catalogs. Each product on the catalog is assigned with a relevant category, which makes it easier for the customers to search and identify the needed products within the catalog. It is possible to add an unlimited number of parameters for each of the categories in the catalog in order to allow a detailed representation of the product on the catalog. Moreover, each product on the catalog can be accompanied with an image. Customers are provided with the possibility of rating the products available on the catalog, as well as writing customer reviews that will appear under the catalog products. Spider Catalog provides you with a high level of customization concerning almost all the aspects of the catalog, ranging from background colors and text size inside the product cell to the number of products in the row and the number of customer reviews per catalog page.
