I try creating as list with drag and drop ordering as described here: https://www.seblod.com/resources/tutorials/adding-drag-and-drop-ordering-functionality-to-your-front-end-managers
I use Joomla 4 with Seblod 4, exactly identical configuration as in another installation of Joomla 3. I think the former field "CCK" now is called "Core ID". In Joomla 4 I can drag a list item, but with mouseup, the item jumps back to the former position.
Dragging works, but the positions don't flip. Also in Joomla administration after dragging, there's an AJAX call like http://www.mydomain.com/administrator/index.php?option=com_content&task=articles.saveOrderAjax&tmpl=component&abcabcabcabcabcabcabc=1 . Seblod doesn't send the call.
StanislavR, can you please post a screenshot of the template config so we can see where you enter the data-draggable-group=... parameter? I don't see an option to enter it, nor was it in there by default. Thank you!
