The Featured product is the product that will be used for both the Product focus and Product goal features. Set it up in the Theme settings before adding sections to either your home page or product page.
Choose the product to feature
Go to Customize > Theme settings > Featured product and select the product you want to feature from the Product dropdown at the top.
The dropdown menus below control the layout sequence of your Featured product sections on the assigned Product. You can opt to use one or none or both of these features. The Product focus feature allows you to display the core highlights of your product using an image and up to four text sections with icons, while the Technical specifications feature displays all the details about your product in an accessible, visually-appealing way.
