SmithCart supports building and displaying a cross-matrix of products by category or department. For example, a parts manufacturer could display a matrix of products with thumbnail images to customers as follows:
The matrix supports one or two x and y axis titles, nine product matrix columns and unlimited product matrix rows. When a user clicks on a thumbnail image or the sku link for a product in the matrix above they will be taken to the product details page where they can select product variants and checkout.
