Create and Edit Field Sets in Lightning Experience
Where: This change applies to Lightning Experience in all editions.
Why: Admins love Lightning Experience, but they were missing the ability to create and edit field sets.
A field set is a grouping of fields. For example, you could have a field set that contains fields describing a user's first name, middle name, last name, and business title. When a field set is added to a Visualforce page, developers can loop over its fields and render them. If the page is added to a managed package, administrators can add, remove, or reorder fields in a field set to modify the fields presented on the Visualforce page without modifying any code. The same Visualforce page can present different sets of information, depending on which fields a subscriber prefers to keep.
How: From Setup, enter Objectin the Quick Find box, and select Object Manager. Select an object that supports field sets, go to Field Sets, and then click New.
