I want to add a lightning quick action in the list view of opportunity. The quick action should use the Lightning component. How to add the quick action with lightning component in the List View?
I'm afraid that's currently not possible (Summer '18).
You can add quick actions to list view but not the ones that are invoking lightning components.
I tried for example to create quick action that creates a record then I added it to a list view from Setup-> Object Manager -> Desired Object -> Search layouts -> List View -> Click edit -> Move quick actions in duallistbox in List View Actions in Lightning Experience section. I was able to add quick action that creates or updates the record, but quick action that invokes lightning component is not visible at all in those lists
