To select and organize related products:
On the Catalog page, navigate to the product to which you want to add related products.
On the product’s Related Products tab, click Manage Products.
Select products to display.
To select products, begin by typing or pasting some text in the box. The list of products that appears matches letters or numbers that you type, wherever they appear in the asset name or ID, not just at the beginning.
Note: If you select inactive products, the Related Products widget will not display them. For more information about active and inactive products, see Understand the base product type.
When you finish adding related products, click Display Products.
The Related Products widget will display the products in the order they appear here. You can rearrange them by dragging them to new positions.
Click Save.
