I am making an event app. I would like the user to be able to invite guests from a list of people. I am able to make the user invite one and one guest from the list of people, by tapping/klicking each one. But I have not found a way to let the user choose and add the whole list at once. Any tips?
Example: The Event has a many-to-many relationship to Users. The logged in user can make his own Lists of Users, e.g. a list called Family - a lilst of the people in his family. Then he should be able to invite the whole family to an event.
