Lightning Quick Action Without Header

Add the force:lightningQuickActionWithoutHeader interface to an Aura component to allow it to be used as a custom action in Lightning Experience or the Salesforce mobile app. You can use these components as object-specific or global actions in both Lightning Experience and the Salesforce mobile app.

When used as actions, components that implement the force:lightningQuickActionWithoutHeader interface display in a panel without additional controls. The component should provide a complete user interface for the action. If you implement force:lightningQuickActionWithoutHeader, you can’t implement force:lightningQuickAction within the same component.

This interface is a marker interface. A marker interface is a signal to the component’s container to add the interface’s behavior to the component. You don’t need to implement any specific methods or attributes in your component, you simply add the interface name to the component’s implements attribute.
