Banners can also include a link to perform an operation (e.g. file transfer) or navigate to another view.

Used for:
Announcements and alerts
Use Banners to announce important updates, promotions, or events to users. For example, notify users about system maintenance, new features, or upcoming events.
Critical information
Display urgent or critical information that requires immediate attention, such as system errors, security alerts, or service disruptions.
System status
Display Banners to communicate the current status of a system, service, or application, such as maintenance downtime, service disruptions, or performance issues.
Don’t use for:
Overuse
Avoid overwhelming users with excessive Banner notifications, as this can lead to Banner fatigue and desensitization. Reserve the Banners for really important information.
Non-Essential notifications
Refrain from using Banners for trivial or non-urgent messages that do not require immediate attention from the users. Consider using the regular notifications panel.
Redundant information
If the information conveyed by a Banner is already available or accessible through other means, such as within the application interface or through system notifications, don’t use Banners.

Behavior
Positioning & Usage
Banners should always be placed at the top of the view they refer to, in order to maintain their hierarchical importance in the view.
The banner has four possible states: informative, success, warning and error.
You can add an action to each Banner. These are links in the text. Depending on the type of message to be presented to the user, you can define the Banner’s appearance.
When there are two Banners, they must be of different types.
Do not use more than two Banners.
