Override a Standard Action with an Aura Component
You can override a standard action with an Aura component in both Lightning
Experience and mobile.
You need at least one Aura component in your org that implements the lightning:actionOverride interface. You can use a custom component of your own, or a component from a managed package.
Go to the object management settings for the object with the action you plan to
override.
- Select Buttons, Links, and Actions.
- Select Edit for the action you want to override.
- Select Lightning component for the area you want to set the override.
- From the drop-down menu, select the name of the Lightning component to use as the action override.
- Select Save.
