The bulk of the footer is divided into a maximum of 5 content blocks. Determine which blocks are featured by selecting [+] Add content.
There are four types of items you can add to your footer. The Social accounts and Newsletter items can be used once, but you can have multiple Menus or Rich text blocks (up to a maximum of 5 footer blocks).
Menu: Display a quick list of links for your customers to easily find your catalog and store policies. To set up a specific menu for this section, head to your Shopify Admin > Online Store > Navigation.
Rich text: Use bold, italics, and hyperlinks in this paragraph to summarize your store’s mission and vision .
Social accounts: Display your social media accounts with stylized icons. Add your accounts via the Theme settings tab > Social media.
Newsletter: Include a signup form for your customers to be added to your mailing list. For more information on how this works, check out Shopify’s guide.
