Override Standard Actions in Lightning Communities
Personalize your communities users’ experience by adding a custom
Lightning component to replace standard forms when users click the New or Edit button. Use action
overrides when your community and portal users require a more customized user experience than the
Salesforce standard page provides.
Where: This change applies to Lightning communities accessed through Lightning Experience and Salesforce Classic in Enterprise, Performance, Unlimited, and Developer editions.
How: To override actions in a community, select the Override standard actions with the Lightning component option in Experience Workspaces > Administration. The action you choose in Lightning Experience is the same action that you use to override actions in Lightning communities.
