Just as you can customize your home page, you can customize page layouts for different record types and objects.
For example, the Contact page layout can hold a lot of detailed information to help keep you organized.
To add more information to the page, such as tabs that contain additional fields, go to Setup and choose Edit Page:
You are now in the Lightning App Builder. There are components listed on the left side that you can add to your layout:
Simply drag and drop the preferred component onto your page. For example, drag Tabs over to the desired area on the page. Be sure to click Save and Activation:
Select Rethink CRE and click Next
Please reach out to Product Support (email@example.com) if you have any questions about adding tabs or other components to page layouts.
