The sbb-dialog component provides a way to present content on top of the app's content.
It offers the following features:

  • creates a backdrop for disabling interaction below the modal;
  • disables scrolling of the page content while open;
  • manages focus properly by setting it on the first focusable element;
  • can host a sbb-dialog-actions component in the footer;
  • has a close button, which is always visible;
  • can display a back button next to the title;
  • adds the appropriate ARIA roles automatically.
  <sbb-dialog-content>Dialog content.</sbb-dialog-content>


There are three slots: title, content and actions, which can respectively be used to provide an sbb-dialog-title, sbb-dialog-content and an sbb-dialog-actions.

  <sbb-dialog-content>Dialog content.</sbb-dialog-content>
    <sbb-block-link sbb-dialog-close>Link</sbb-block-link>
    <sbb-secondary-button sbb-dialog-close> Cancel </sbb-secondary-button>
    <sbb-button sbb-dialog-close> Confirm </sbb-button>


In order to show the dialog, you need to call the open(event?: PointerEvent) method on the sbb-dialog component.
It is necessary to pass the event object to the open() method to allow the dialog to detect
whether it has been opened by click or keyboard, so that the focus can be better handled.

  label="Open dialog"
  click="openDialog(event, 'my-dialog')"

<sbb-dialog id="my-dialog">
  <sbb-dialog-content>Dialog content.</sbb-dialog-content>

  const openDialog = (event, id) => {
    const dialog = document.getElementById(id);

To dismiss the dialog, you need to get a reference to the sbb-dialog element and call
the close(result?: any, target?: HTMLElement) method, which will close the dialog element and
emit a close event with an optional result as a payload.

The component can also be dismissed by clicking on the close button, clicking on the backdrop, pressing the Esc key,
or, if an element within the sbb-dialog has the sbb-dialog-close attribute, by clicking on it.

You can also set the property backButton on the sbb-dialog-title component to display the back button in the title section which will emit the event requestBackAction when clicked.


It's possible to display the component in negative variant using the self-named property.

<sbb-dialog negative>
  <sbb-dialog-content>Dialog content.</sbb-dialog-content>


When using a button to trigger the dialog, ensure to manage the appropriate ARIA attributes on the button element itself. This includes: aria-haspopup="dialog" that signals to assistive technologies that the button controls a dialog element,
aria-controls="dialog-id" that connects the button to the dialog by referencing the dialog's ID. Consider using aria-expanded to indicate the dialog's current state (open or closed).

The sbb-dialog component may visually hide the title thanks to the hideOnScroll property of the sbb-dialog-title to create more space for content, this is useful especially on smaller screens. Screen readers and other assistive technologies will still have access to the title information for context.
