3 years ago Looking into this, it seems to be a clash with the Yoast SEO plugin. For some reason Yoast's select2.full.min.js seems to be rewriting the list elements for this custom fields select UI. The elements end up with data-select2-id attributes, but the ID in the data that this Select2 plugin's script.js (line 21) is looking for is gone, creating a JS error when a drag-and-drop happens.
I'm not sure if the Yoast code is interfering where it shouldn't or if the code here isn't written in the right way to not be interfered with?
Is there an issue with ordering when using Gutenberg?
I've been using this plugin's drag-and-drop ordering for a while, but this issue has just arisen. The field saves the correct items, but always in the order that they're in in the hidden select (not the drag-and-drop UI).
I've traced this back to /cmb2/includes/CMB2.php line 753 (in save_fields()), where the values in $_POST are passed through - and there, the values for my field are in the order of the hidden select element, not the drag-and-drop UI. Might there be an issue here with the JS - presumably it would have been responsible for re-ordering things before submission, but the Gutenberg environment is interfering with this?
