Dialog
A dialog is a window that passes on information to a user and prompts him for a response.
Usage
When to use
Use a dialog in the following cases:
- When you need to draw attention to an important piece of information.
- When you need the user to input information, especially if that information is necessary to continue.
- When you want to show additional information without losing the context of the parent page, for example showing larger images or videos.
- When you want to show information that is not directly related to the parent page, for example “What’s new” dialog.
Types
There are the following dialog types:
Dialog with forced interaction
Use this type when an interaction is needed from the user to continue.
Confirm dialog
Use this type to reduce the risk that people automatically agree to a warning without realizing the consequences. For more information see chapter Confirm dialog.
Dialog with a detail view
Use this type to display detail information about an object.
General construction
A dialog consists of the following elements:
Type: Dialog with forced interaction
1. Header bar
- The header bar contains the title.
2. Descriptive title
- The button label which launches the dialog window should generally match with the dialog title or at least be recognizably related to it.
3. Content
- Content of a dialog with forced interaction can be for example a form, an image or text.
4. Footer bar with buttons
- A footer bar helps to separate the content area from the submit and cancel buttons.
- The button labels inform the user about the action that is triggered by clicking the button.
5. Overlay
- The screen dimming overlay is always located above all other content.
- It lets the user know that the page is currently not active.
6. Background
- The dialog has a drop shadow.

Options
The following dialog options are available:
Sizing
- The dialog adapts to the size of its content.
- There are three widths that can be used: small, medium and large.
- The height of a dialog is determined by the length of its content. The maximum height of the container is determined by its exterior margin. If the content is longer than the length of the dialog, the user can scroll within the dialog.
- The heights of the header bar and the optional footer bar are fixed.
Frameless
Use the frameless option if the content does not require a margin, for example:
- Image
- Graphic elements like a map
- Framed table, which already has a spacing
