Dialog is a window that opens over the application content, focusing the user’s attention on a particular task or piece of information. It can communicate new information, errors, warnings, or successful completion of a process or task.


The dialog displays with a header, content area, and action bar. The component is modal, meaning it prevents interaction with the rest of the UI while open and must be addressed by clicking one of the action buttons or dismissing with the close button. If the content of the dialog extends beyond the end of the screen, the DialogContent area will become scrollable.
