Ability to add non-disabled checkboxes

Hey @endless_wander, I will work on it.

hello @endless_wander
I've added MR with a new filter which will remove the disabled attribute from to-do list (it will be present in the text format edit form in the section Enabled filters). Please check if it works for your case.

MR from #5 works for me. Thank you very much for adding that. The solution feels a bit strange still. What is the use-case for adding disabled checkboxes to a page? I wonder if having the checkboxes be enabled shouldn't be the default? What would be amazing is if the checkbox button within CKEditor had its own option for disabling the checkbox so that both options are available for all users directly from the editor.

Yes, this is a workaround solution, To-Do List is a plugin provided by the core of CKEditor5, we only implement it in Drupal, so we can't easily change how it behaves, your proposed changes should be added to the official ckeditor5 repo on GitHub.

Understood. On the example page for the CKEditor plugin, the checkboxes do not insert as disabled however: https://ckeditor.com/docs/ckeditor5/latest/features/lists/todo-lists.html

On the demo page, there is the editor instance like in the node edit form in Drupal where checkboxes are also not disabled.

@dolszewski I'm not sure what demo page you are referring to

He meant the page you linked. Checkboxes are enabled when content is being edited. However the content retrieved to save into database (editor.getData()) will return disabled checkboxes. So it is the default behavior of CKEditor 5 itself. You can see it briefly before editor is loaded or when JS is disabled or by executing console.log(editor.getData()) in the developer console.

This we can easily altered in Drupal with text filter, by removing disabled attribute on content load.
In order to have ability to save checkboxes not disabled to database the "To-do lists" CKEditor 5 plugin itself had to be changed. Such change can be requested on CKEditor 5 github https://github.com/ckeditor/ckeditor5/issues

I have created an issue with CKEditor. An easier way to check that CKEditor is creating disabled checkboxes by default is to go to their full feature example at https://ckeditor.com/docs/ckeditor5/latest/examples/builds-custom/full-f... and check the source when adding a to-do list.

CKEditor maintainer responded that they will not add this feature and checkboxes can only be added in "disabled" state
