<paper-dialog>

<paper-dialog> is a dialog with Material Design styling and optional animations when it is opened or closed. It provides styles for a header, content area, and an action area for buttons. You can use the <paper-dialog-scrollable> element (in its own repository) if you need a scrolling content area. To autofocus a specific child element after opening the dialog, give it the autofocus attribute. See PaperDialogBehavior and IronOverlayBehavior for specifics.

For example, the following code implements a dialog with a header, scrolling content area and buttons. Focus will be given to the dialog-confirm button when the dialog is opened.

<paper-dialog>
  <h2>Header</h2>
  <paper-dialog-scrollable>
    Lorem ipsum...
  </paper-dialog-scrollable>
  <div class="buttons">
    <paper-button dialog-dismiss>Cancel</paper-button>
    <paper-button dialog-confirm autofocus>Accept</paper-button>
  </div>
</paper-dialog>

Styling

See the docs for PaperDialogBehavior for the custom properties available for styling this element.

Animations

Set the entry-animation and/or exit-animation attributes to add an animation when the dialog is opened or closed. See the documentation in PolymerElements/neon-animation for more info.

For example:

<script type="module">
  import '@polymer/neon-animation/animations/scale-up-animation.js';
  import '@polymer/neon-animation/animations/fade-out-animation.js';
</script>

<paper-dialog entry-animation="scale-up-animation"
              exit-animation="fade-out-animation">
  <h2>Header</h2>
  <div>Dialog body</div>
</paper-dialog>
