Collection list sections are designed to help you showcase new or seasonal collections on your home page. With Empire you can feature up to twenty collections per section.
You can apply whatever heading you like to your collection list using the Heading field under Settings. Note that this is optional, and if you do not want to include a heading, you can leave the field blank and nothing will appear.
Here, you can select the collection(s) you want to display by clicking Add collection or one of the existing Collection blocks, then selecting the collection you want to feature from the Collection dropdown. You can set up collections in the Products > Collections section of your Shopify admin. For instructions on how to set up collections see here: Getting Started: Shopify Basics.
By default, Empire will pull either the collections image (set on the right side of the collections screen in your Shopify admin) or the first product. If you'd like to use an alternate image, you can click the Upload image button and select one from your computer (or library).
