>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3513611. --> Reported by: [murz](https://www.drupal.org/user/157092) Related to !57 >>> <h3 id="summary-problem-motivation">Problem/Motivation</h3> <p>Now the content blocks use the submit action and reload the full page, which works pretty slowly.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>It would be great to implement AJAX reload of all related blocks of the configured "product_list_index" on the submit event of one of the product list modifier blocks (Search, Filters, Order).</p> <p>Would be good to implement a universal way to trigger the re-rendering of the blocks from the backend by a subscribed JS event. You can take a look at the BigPipe module implementation as an example.</p> <p>And, together with this, get rid of the legacy <code>/ajax/[catalog-url]</code> endpoint.</p>
