Drupal.behaviors.xbDisableLinks doesn't disable links added to the DOM later

Created on 9 July 2025, 18 days ago

Overview

When you click "Preview" in XB, you can see a preview of the page you're building, without the XB sidebars and canvas overlay, so you can click on the page's interactive elements. However, we disable clicking links to navigate away from the page entirely. We do this with Drupal.behaviors.xbDisableLinks.

However, Drupal behaviors only run after the page is initially loaded, and after Drupal AJAX operations complete. Drupal behaviors don't run when, for example, React components that are on the page re-render in response to a state change, such as when using the Navigation component in 📌 Build a navigation code component Active .

Proposed resolution

Change xbDisableLinks from a Drupal behavior to a mutation observer (or any other technique for monitoring links that get added to the DOM). Or, keep the Drupal behavior but also add a mutation observer for catching subsequent links added outside of Drupal's AJAX operations.

I think I hit this with a "simpler" scenario. I have a button link component within the slot of a another component. The page is then visited within the iframe. The problem does not occur if the button link is on its own and not in a slot.

Oh, and this effects anything using dynamic code components – menus for example.

Unassigning as I'm not working on this right now, in case anyone would pick it up.
