This block lets you divide your content into tabs vertically.
NOTE: This block is only available for the PRO plan. You can configure this block normally in the Theme Editor; however, you need to upgrade your plan to apply them to the front end.
From the Shopify theme editor, click on Tabs on the sidebar to view the details of settings.
