Alert

An alert is a notification that provides brief information to the user without blocking their workflow.

Examples

Variant examples

PatternFly supports several alert variants for different scenarios. Each variant has an associated status icon, background, and alert title coded to communicate the severity of an alert. Use the variant property to apply the following styling options. If no variant is specified, then the variant will be set to "default".

Variant
Description
Default
Use for generic messages with no associated severity
Info
Use for general informational messages
Success
Use to indicate that a task or process has been completed successfully
Warning
Use to indicate that a non-critical error has occurred
Danger
Use to indicate that a critical or blocking error has occurred

Default alert:Default alert title

Info alert:Info alert title

Success alert:Success alert title

Warning alert:Warning alert title

Danger alert:Danger alert title

Alert variations

PatternFly supports several properties and variations that can be used to add extra content to an alert.

  • As demonstrated in the 1st variation below, use the actionLinks property to add one or more <AlertActionLink> components that place links beneath the alert message. You must pass in href and component="a" properties to have an <AlertActionLink> act as a proper link, rather than as a button.

  • As demonstrated in the 2nd variation below, use a native HTML <a> element to add links within an alert message.

  • As demonstrated in the 3rd and 4th variations below, use the actionClose property to add an <AlertActionCloseButton> component, which can be used to manage and customize alert dismissals. actionClose can be used with or without the presence of actionLinks.

  • As demonstrated in the 5th and 6th variations below, use the component property to set the element for an alert title.

    • If the description prop is not passed in, then the component prop should be set to a non-heading element such as a span or div.
    • If the description prop is passed in, then the component prop should be a heading element. Headings should be ordered by their level and heading levels should not be skipped. For example, a heading of an h2 level should not be followed directly by an h4.

Success alert:Success alert title

Success alert description. This should tell the user more information about the alert.

Success alert:Success alert title

Success alert:div success alert title
Success alert:h6 Success alert title

Short alert description

Alert timeout

Use the timeout property to automatically dismiss an alert after a period of time. If set to true, the timeout will be 8000 milliseconds. Provide a specific value to dismiss the alert after a different number of milliseconds.

    Expandable alerts

    An alert can contain additional, hidden information that is made visible when users click a caret icon. This information can be expanded and collapsed each time the icon is clicked.

    It is not recommended to use an expandable alert with a timeout in a toast alert group because the alert could timeout before users have time to interact with and view the entire alert.

    See the toast alert considerations section of the alert accessibility documentation to understand the accessibility risks associated with using toast alerts.

    Truncated alerts

    Use the truncateTitle property to shorten a long title. Set truncateTitle equal to a number (passed in as {n}) to reduce the number of lines of text in the alert's title. Users may hover over or tab to a truncated title to see the full message in a tooltip.

    Danger alert: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur pellentesque neque cursus enim fringilla tincidunt. Proin lobortis aliquam dictum. Nam vel ullamcorper nulla, nec blandit dolor. Vivamus pellentesque neque justo, nec accumsan nulla rhoncus id.

Mauris et rhoncus leo.

    Custom icons

    Use the customIcon property to replace a default alert icon with a custom icon.

    Default alert:Default alert title

    Info alert:Info alert title

    Success alert:Success alert title

    Warning alert:Warning alert title

    Danger alert:Danger alert title

    Inline alerts variants

    Use inline alerts to display an alert inline with content. All alert variants may use the isInline property to position alerts in content-heavy areas, such as within forms, wizards, or drawers.

    Default alert:Default inline alert title

    Info alert:Info inline alert title

    Success alert:Success inline alert title

    Warning alert:Warning inline alert title

    Danger alert:Danger inline alert title

    Inline alert variations

    All general alert variations can use the isInline property to apply inline styling.

    Success alert:Success alert title

    Success alert description. This should tell the user more information about the alert.

    Success alert:Success alert title

    Success alert description. This should tell the user more information about the alert. This is a link.

    Success alert:Success alert title

    Success alert:Success alert title

    Success alert:Success alert title

    Plain inline alert variants

    Use the isPlain property to make any inline alert plain. Plain styling removes the colored background but keeps colored text and icons.

    Default alert:Default inline alert title

    Info alert:Info inline alert title

    Success alert:Success inline alert title

    Warning alert:Warning inline alert title

    Danger alert:Danger inline alert title

    Plain inline alert variations

    It is not recommended to use a plain inline alert with actionClose nor actionLinks because these alerts are non-dismissible and should persist until the error or action related to the alert is resolved.

    Success alert:Success alert title

    Success alert description. This should tell the user more information about the alert.

    Static live region alerts

    Live region alerts allow you to expose dynamic content changes in a way that can be announced by assistive technologies.

    By default, isLiveRegionalerts are static.

    Info alert:Default live region configuration

    This alert uses the recommended isLiveRegion prop to automatically set ARIA attributes and CSS classes.

    Info alert:Customized live region

    You can alternatively omit the isLiveRegion prop to specify ARIA attributes and CSS manually on the containing element.

    Dynamic live region alerts

    Alerts that are asynchronously appended into dynamic alert groups via the isLiveRegion property will be announced to assistive technology the moment the change happens, following the strategy used for aria-atomic, which defaults to false. This means only changes of type "addition" will be announced.

      Asynchronous live region alerts

      This example shows how an alert could be triggered by an asynchronous event in the application. Note that you can customize how the alert will be announced to assistive technology. See the [https://www.patternfly.org/2023.02/components/alert/accessibility](alert accessibility) for more information.
