<wa-dialog> Stable Since 2.0

Dialogs appear above the page and require the user’s immediate attention. Use them for confirmations, forms, or focused tasks that interrupt the main flow.

<wa-dialog label="Dialog" id="dialog-overview">
  This is a standard dialog. You can put any content you want in here!
  <wa-button appearance="filled" slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('#dialog-overview');
  const openButton = dialog.nextElementSibling;

  openButton.addEventListener('click', () => (dialog.open = true));
</script>

Dialog without Header dialog without header link

Headers are enabled by default. To render a dialog without a header, add the without-header attribute.

<wa-dialog label="Dialog" without-header class="dialog-without-header">
  Look ma, no header! Sometimes you just need a clean, simple dialog.
  <wa-button slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('.dialog-without-header');
  const openButton = dialog.nextElementSibling;

  openButton.addEventListener('click', () => (dialog.open = true));
</script>

Footers can be used to display titles and more. Use the footer slot to add a footer to the dialog.

<wa-dialog label="Dialog" class="dialog-footer">
  Check out the footer below — it's a great place for actions and buttons.
  <wa-button slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('.dialog-footer');
  const openButton = dialog.nextElementSibling;

  openButton.addEventListener('click', () => (dialog.open = true));
</script>

Opening and Closing Dialogs Declaratively opening and closing dialogs declaratively link

You can open and close dialogs with JavaScript by toggling the open attribute, but you can also do it declaratively. Add the data-dialog="open id" to any button on the page, where id is the ID of the dialog you want to open.

<wa-dialog label="Dialog" id="dialog-opening">
  This dialog was opened declaratively — no JavaScript required!
  <wa-button slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled" data-dialog="open dialog-opening">Open Dialog</wa-button>

Similarly, you can add data-dialog="close" to a button inside of a dialog to tell it to close.

<wa-dialog label="Dialog" id="dialog-dismiss">
  Click the button in the footer to close this dialog declaratively.
  <wa-button slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled" data-dialog="open dialog-dismiss">Open Dialog</wa-button>

Custom Width custom width link

Just use the --width custom property to set the dialog’s width.

<wa-dialog label="Dialog" class="dialog-width" style="--width: 50vw;">
  This dialog is wider than the default — handy when you need more room for content.
  <wa-button appearance="filled" slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('.dialog-width');
  const openButton = dialog.nextElementSibling;

  openButton.addEventListener('click', () => (dialog.open = true));
</script>

Scrolling scrolling link

By design, a dialog’s height will never exceed that of the viewport. As such, dialogs will not scroll with the page ensuring the header and footer are always accessible to the user.

<wa-dialog label="Dialog" class="dialog-scrolling">
  <div style="height: 150vh; border: dashed 2px var(--wa-color-surface-border); padding: 0 1rem;">
    <p>Scroll down and give it a try! 👇</p>
  </div>
  <wa-button slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('.dialog-scrolling');
  const openButton = dialog.nextElementSibling;

  openButton.addEventListener('click', () => (dialog.open = true));
</script>

Header Actions header actions link

The header shows a functional close button by default. You can use the header-actions slot to add additional buttons if needed.

<wa-dialog label="Dialog" class="dialog-header-actions">
  <wa-button class="new-window" slot="header-actions" appearance="plain">
    <wa-icon name="arrow-up-right-from-square" variant="solid" label="Open in new window"></wa-icon>
  </wa-button>
  You can add custom actions to the header, like the icon button up there!
  <wa-button slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('.dialog-header-actions');
  const openButton = dialog.nextElementSibling;
  const newWindowButton = dialog.querySelector('.new-window');

  openButton.addEventListener('click', () => (dialog.open = true));
  newWindowButton.addEventListener('click', () => window.open(location.href));
</script>

Light Dismissal light dismissal link

If you want the dialog to close when the user clicks on the overlay, add the light-dismiss attribute.

<wa-dialog label="Dialog" light-dismiss class="dialog-light-dismiss">
  This dialog will close when you click on the overlay.
  <wa-button slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('.dialog-light-dismiss');
  const openButton = dialog.nextElementSibling;

  openButton.addEventListener('click', () => (dialog.open = true));
</script>

Preventing the Dialog from Closing preventing the dialog from closing link

By default, dialogs will close when the user clicks the close button or presses the Escape key. In most cases, the default behavior is the best behavior in terms of UX. However, there are situations where this may be undesirable, such as when data loss will occur.

To keep the dialog open in such cases, you can cancel the wa-hide event. When canceled, the dialog will remain open and pulse briefly to draw the user’s attention to it.

You can use event.detail.source to determine which element triggered the request to close. This example prevents the dialog from closing unless a specific button is clicked.

<wa-dialog label="Dialog" class="dialog-deny-close">
  This dialog will only close when you click the button below.
  <wa-button slot="footer" variant="brand" data-dialog="close">Only this button will close it</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('.dialog-deny-close');
  const openButton = dialog.nextElementSibling;
  const closeButton = dialog.querySelector('wa-button[slot="footer"]');

  openButton.addEventListener('click', () => (dialog.open = true));

  // Prevent the dialog from closing unless the close button was clicked
  dialog.addEventListener('wa-hide', event => {
    if (event.detail.source !== closeButton) {
      event.preventDefault();
    }
  });
</script>

Setting Initial Focus setting initial focus link

To give focus to a specific element when the dialog opens, use the autofocus attribute.

<wa-dialog label="Dialog" class="dialog-focus">
  <wa-input autofocus placeholder="I will have focus when the dialog is opened"></wa-input>
  <wa-button slot="footer" variant="brand" data-dialog="close">Close</wa-button>
</wa-dialog>

<wa-button appearance="filled">Open Dialog</wa-button>

<script>
  const dialog = document.querySelector('.dialog-focus');
  const input = dialog.querySelector('wa-input');
  const openButton = dialog.nextElementSibling;

  openButton.addEventListener('click', () => (dialog.open = true));
</script>
