Drupal HTMX Example Demonstrates Tabbed Interface Without Page Reload

A tutorial by Phil Norton demonstrates how HTMX can be used in Drupal to build a tabbed interface that loads content dynamically without requiring a full page reload. The example shows how server-rendered HTML can be updated in place while keeping frontend complexity low.

Published on Hashbangcode, the tutorial uses a single controller to handle both the initial page load and subsequent HTMX requests. It relies on Drupal services such as the request stack, route matching, and the HTMX renderer to generate partial responses, allowing only targeted sections of the page to update.

The implementation includes generating tab links with HTMX attributes, loading content dynamically from the database based on user interaction, and replacing a target container with returned markup. It also demonstrates handling HTMX request headers and applying cache metadata, offering a practical pattern for introducing lightweight interactivity within Drupal’s server-driven rendering model.
