Doorhangers provide a way to present decisions to users which is less intrusive than a modal dialog.
Doorhangers are used for prompt and notification; they are used for full featured UI; or they are used for list and menu as in the example on the left.
Doorhangers opening on the right side of the view show the directional arrow on the right.
Doorhangers opening on the left side of the view show the directional arrow on the left.
Never place the directional arrow at the center of doorhangers.
