3.5.0 Theme breaks Drupal drag and drop functionality

[LOBsTerr]

after update to 3.5.0 we can drag the item, but we can't drop them anymore. For example when we edit a node with paragraphs or table with drag and drop feature. To reproduce we need sortable table, where we can drag and drop items and also set their weight

Actually, we found the reason the select components doesn't apply necessary Drupal classes in ecl-select.html.twig:

{% set _css_group_class = 'ecl-form-group' %}
{% set _css_class = ['ecl-select'] %}
{% set _css_class = _css_class|join(' ') %}

And this breaks drag and drop. This our fix:

{% set _css_group_class = 'ecl-form-group' %}
{% set _css_class = ['ecl-select'] %}
{% set _css_class = _css_class|merge(attributes.class) %}

To be more precise we are missing this class "table-sort-weight".

Hi @LOBsTerr, could you please point to some pages where this can be seen? Using oe_theme for editing and creating content doesn't seem to allow drag&drop at all and the oe_theme table.html.twig template uses the ECL Table component (ecl-table.html.twig).

The ecl-select.html.twig template is used for the select form element.

Hi @22Alexandra, we managers the admin is not allow and they are using oe_theme to update the content and change the configuration of their groups.

I think the easiest way to add a paragraph field and add a few paragraphs then you can see drag and drop feature there. And it is broken, because of the missing classes
