Dialogs contain text and UI controls. They retain focus until
dismissed or a required action has been taken. Use dialogs sparingly
because they are interruptive.
Some dialog types include:
Alerts are urgent interruptions
that inform about a situation and require acknowledgement.
Simple menus
display options for list items, whereas simple dialogs can provide
details or actions about a list item.
Confirmation dialogs
require users to explicitly confirm a choice.
