The D-Tools Library is where you can easily search for products to add to your products list. Use the left side facets to narrow your search, or check a box to narrow it further by brand. You also have the ability to search through categories or brands to assist in helping narrow your results.
You can quickly add products to your catalog by hovering over an item. To view further details about that product, double click on the product to bring up the detailed view. Once a product is in your catalog, you can freely edit the quantity and other information.
