A static list is a tag (StaticList) that can be applied to group products together. They are similar to brands, genders, styles, etc. However, static lists are unique in that you can upload a CSV file of products and assign a static list to each one.
This article details how to create a new StaticList tag using a CSV upload then use that tag in recommendations.
Before you begin, you'll need to create a CSV file for the upload similar to the image at the right, with products entered for cell 1A and, starting at cell 2A, the product IDs for each product that you want to associate (or disassociate) with the StaticList tag.
You will only see your static list when you navigate to Catalog > Product Lists if the list is named exactly StaticList.
Once products have been uploaded to a static list, associate the products to a related catalog object so you can use your static list in recipe exclusions and boosters.
