hi i am doing a project in angular material whaich have many components in side bar i want to implement a select option in side bar to show only selected ones.Any hint or reference to some documentation will be highly appreciated.Thanks
as per your explanation: your sidebar is a parent component that includes child components and you want a way to communicate interaction with these children through the parent.
