Responsive viewports with iframes

Created on 19 August 2025, about 1 month ago

Problem/Motivation

Follow-up of ✨ Manage breakpoints & add viewports switcher Active . We may need to use iframe HTML element in Builder & Preview, in order to let the browser recalculate the viewport dimension.

Proposed resolution

So, with an HTTP HTML endpoint to open only a display builder instance, with a specific profile and only one island, whatever this island is. The island rendering on the main window will "only" be a iframe to this HTTP HTML endpoint.

Careful:

  • In general, about performance issue and implementation complexity
  • Do the islands in the iframe react well to HTMX events from the main page? And the other way around? We may need ✨ Add real-time collaboration Active to land and maybe move OOB swap to SSE
  • Can we drop a draggable to an an iframe island with SortableJS? This may be the main challenge to overcome.

A commit was already pushed in a dedicated branch of ✨ Manage breakpoints & add viewports switcher Active : https://git.drupalcode.org/issue/display_builder-3538435/-/tree/iframes
