The InfoBar control is for displaying app-wide status messages to users that are highly visible yet non-intrusive. There are built-in security levels to easily indicate the type of message shown as well as the option to include your own call to action or hyperlink button.

import { InfoBar } from "fluent-svelte";


Text Contents - title and message

There are two areas of text that can be customized - the title and the message. Both are optional, but at least one is recommended.

  • You can specify a title for the InfoBar using title property.
  • You can set the InfoBar’s message using the message property.

If you need to include HTML content into the message, you can also just use the default slot.

InfoBars can take in a severity prop, which represent the type of information you wish to convey to the user. The default severity is information.

Severity Badge Usage Preview
information Non-critical messages containing general information.
attention Messages that are non-critical, but still important to the user.
success Messages that convey an action that has postively been completed.
caution Messages that serve to warn the user of a potentially dangerous action.
critical Higher-severity messages that convey a dangerous or failed action.

Action Buttons

An action button can be passed in using the action slot. It’s recommended that you use the Button component for this, but any HTML element is valid.

<Infobar title="Title" message="Message">
    <Button slot="action">Action</Button>

Controlling Visibility

Flyouts by default are open. This means that they are rendered into the DOM. When the close button is pressed, they will be removed from the DOM and the open property will be set to false.

You can configure a flyout’s default visibility state when it is rendered by setting the open property.

<InfoBar open={false} />

You can also use two-way binding to programatically control a bar’s visibility.

    import { InfoBar, Button } from "fluent-svelte";

    let open = false;

<Button on:click={() => open = !open}>Toggle InfoBar</Button>

<InfoBar bind:open />

If you don’t want an InfoBar to be closable by the user, you can set the closable property to false which will hide the close button.

Custom Icons

The icon slot can be used to override the default badge for the InfoBar and provide your own.
