Your newest collection field is Social Accounts, which enables you to add social accounts / social icons to your Dynamic Pages.
Collections and Dynamic Pages make it easier to build multi-page websites for your clients. Your newest field addition is Social Media accounts and it enables you to automatically add social media info that’s saved in a collection to a Dynamic Page.
For example, let’s say you’ve used a Dynamic Page to build a team page on your site. You can now add social account info for each member of the team to the collection connected to that page. If a team member’s details change, or a new team member is added, you can just update the collection and the website will update accordingly.
Social accounts are available in all collection types: Internal Collections, Google Sheets, Airtable and External Databases.
