<paper-toast>

paper-toast provides a subtle notification toast. Only one paper-toast will be visible on screen.

Use opened to show the toast:

Example:

<paper-toast text="Hello world!" opened></paper-toast>

Also open() or show() can be used to show the toast:

Example:

<paper-button on-click="openToast">Open Toast</paper-button>
<paper-toast id="toast" text="Hello world!"></paper-toast>

...

openToast: function() {
  this.$.toast.open();
}

Set duration to 0, a negative number or Infinity to persist the toast on screen:

Example:

<paper-toast text="Terms and conditions" opened duration="0">
  <a href="#">Show more</a>
</paper-toast>

<paper-toast> is affected by the stacking context of its container. Adding <paper-toast> inside elements that create a new stacking context - e.g. <app-drawer>, <app-layout> or <iron-list> - might result in toasts partially obstructed or clipped. Add <paper-toast> to the top level (<body>) element, outside the structure, e.g.:

  <!-- ... -->
  </app-drawer-layout>
  <paper-toast id="toast"></paper-toast>
</template>

You can then use custom events to communicate with it from within child components, using addEventListener and dispatchEvent.

Styling

The following custom properties and mixins are available for styling:

Custom property	Description	Default
`--paper-toast-background-color`	The paper-toast background-color	`#323232`
`--paper-toast-color`	The paper-toast color	`#f1f1f1`

This element applies the mixin --paper-font-common-base but does not import paper-styles/typography.html. In order to apply the Roboto font to this element, make sure you've imported paper-styles/typography.html.

See: Documentation, Demo.
