Alert
Alerts are used to display important messages either inline or as toast notifications.
<six-alert open>
<six-icon slot="icon">info</six-icon>
This is a standard alert. You can customize its content and even the icon.
</six-alert>
warning
Alerts will not be visible if the open
attribute is not present.

</six-alert>
closable
Add the closable
attribute to show a close button that will hide the alert.
<six-alert type="primary" open closable class="alert-closable">
<six-icon slot="icon">info</six-icon>
You can close this alert any time!
</six-alert>
<script type="module">
(() => {
const alert = document.querySelector('.alert-closable');
alert.addEventListener('six-alert-after-hide', () => {
setTimeout(() => {
alert.open = true;
}, 2000);
});
})();
</script>
Without Icons
Icons are optional. Simply omit the icon
slot if you don't want them.
<six-alert type="primary" open> Nothing fancy here, just a simple alert. </six-alert>
Duration
Set the duration
prop to automatically hide an alert after a period of time. This is useful for alerts that don't require acknowledgement.
<div class="alert-duration">
<six-button type="primary">Show Alert</six-button>
<six-alert type="primary" duration="3000" closable>
<six-icon slot="icon">info</six-icon>
This alert will automatically hide itself after three seconds, unless you interact with it.
</six-alert>
</div>
<script type="module">
(() => {
const container = document.querySelector('.alert-duration');
const button = container.querySelector('six-button');
const disappearingAlert = container.querySelector('six-alert');
button.addEventListener('click', () => disappearingAlert.show());
})();
</script>
<style>
.alert-duration six-alert {
margin-top: var(--six-spacing-medium);
}
</style>
Toast Notifications
To display an alert as a toast notification, or "toast", create the alert and call its `toast()` method. This will move the alert out of its position in the DOM and into the toast stack where it will be shown. Once dismissed, it will be removed from the DOM completely. To reuse a toast, store a reference to it and call toast()
again later on.
You should always use the closable
prop so users can dismiss the notification. It's also common to set a reasonable duration
when the notification doesn't require acknowledgement.

<script type="module">
(() => {
const alertToastContainer = document.querySelector('.alert-toast');
Object.entries({
primary: 'primary',
success: 'success',
info: 'secondary',
warning: 'warning',
danger: 'danger',
}).map(([alertType, buttonType]) => {
const button = alertToastContainer.querySelector(`#${buttonType}-button`);
const alert = alertToastContainer.querySelector(`#${alertType}-alert`);
button.addEventListener('click', () => alert.toast());
});
})();
</script>
Angular and Vue Utilities
The wrapper libraries for Angular and Vue offer a simpler way to create toast alerts:
- Angular: Inject the `alertService` and utilize the `showAlert` method
this.alertService.showAlert('The Alert Message');
- Vue: Use
showAlert
by importing it from'@six-group/ui-library'
and then invoke itshowAlert('The Alert Message');
Creating Toasts Imperatively
You can also create your own utility that emits toast notifications with a function call rather than composing them in your HTML. To do this, generate the alert with JavaScript, append it to the body, and call the toast()
method as shown in the example below.
<div class="alert-toast-wrapper">
<six-button type="primary">Create Toast</six-button>
</div>
<script type="module">
(() => {
const alertToastImpContainer = document.querySelector('.alert-toast-wrapper');
const toastCreatorButton = alertToastImpContainer.querySelector('six-button');
let count = 0;
// Always escape HTML for text arguments!
function escapeHtml(html) {
const div = document.createElement('div');
div.textContent = html;
return div.innerHTML;
}
// Custom function to emit toast notifications
function notify(message, type = 'primary', icon = 'info', duration = 3000) {
const alert = Object.assign(document.createElement('six-alert'), {
type: type,
closable: true,
duration: duration,
innerHTML: `
<six-icon slot="icon">${icon}</six-icon>
${escapeHtml(message)}`,
});
document.body.append(alert);
return alert.toast();
}
toastCreatorButton.addEventListener('click', () => {
const possibleTypes = ['primary', 'success', 'info', 'warning', 'danger'];
const drawnNumber = Math.round(Math.random(0, 1) * 5) + 1;
notify(`This is custom toast #${++count}`, possibleTypes[drawnNumber]);
});
})();
</script>
The Toast Stack
The toast stack is a fixed position singleton element created and managed internally by the alert component. It will be added and removed from the DOM as needed when toasts are shown. When more than one toast is visible, they will stack vertically in the toast stack.
By default, the toast stack is positioned at the top-right of the viewport. You can change its position by targeting .six-toast-stack
in your stylesheet. To make toasts appear at the top-left of the viewport, for example, use the following styles.
By design, it is not possible to show toasts in more than one stack simultaneously. Such behavior is confusing and makes for a poor user experience.
Properties
Property | Attribute | Description | Type | Default |
---|---|---|---|---|
closable | closable | Set to true to make the alert closable. | boolean | false |
duration | duration | The length of time, in milliseconds, the alert will show before closing itself. If the user hovers over the toast alert, the timer will pause. On leaving the element with the mouse, the timer resets. | number | Infinity |
open | open | Indicates whether or not the alert is open. You can use this in lieu of the show/hide methods. | boolean | false |
type | type | The type of alert. | "danger" | "info" | "primary" | "success" | "warning" | 'primary' |
Events
Event | Description | Type |
---|---|---|
six-alert-after-hide | Emitted after the alert closes and all transitions are complete. | CustomEvent<undefined> |
six-alert-after-show | Emitted after the alert opens and all transitions are complete. | CustomEvent<undefined> |
six-alert-hide | Emitted when the alert closes. Calling event.preventDefault() will prevent it from being closed. | CustomEvent<undefined> |
six-alert-show | Emitted when the alert opens. Calling event.preventDefault() will prevent it from being opened. | CustomEvent<undefined> |
Methods
hide() => Promise<void>
Hides the alert
Returns
Type: Promise<void>
show() => Promise<void>
Shows the alert.
Returns
Type: Promise<void>
toast(adjustPosition?: boolean) => Promise<void>
Displays the alert as a toast notification. This will move the alert out of its position in the DOM and, when dismissed, it will be removed from the DOM completely. By storing a reference to the alert, you can reuse it by calling this method again. The returned promise will resolve after the alert is hidden.
Parameters
Name | Type | Description |
---|---|---|
adjustPosition | boolean | If true, the top and right position of the toast stack is shifted according to the six-root header's height and the presence of a vertical scrollbar. |
Returns
