CKEditor 5 Style plugin configuration tab does not appear

I came across this issue too.

The work around suggested in #5 did not work in my case. Even I click anywhere else in the UI before clicking save button, it still did not work.

The reason is that I have a contribute module called 'Events Log Track' installed which adds a submit handler function to every single form including the format config form. This causes following code at line 686 in Drupal\ckeditor5\Plugin\Editor::CKEditor5 failed to recognise it is a special AJAX updates.

      // Special case: AJAX updates that do not submit the form (that cannot
      // result in configuration being saved).
      if ($form_state->getSubmitHandlers() === ['editor_form_filter_admin_format_editor_configure']) {

If I change that line to:

if (in_array('editor_form_filter_admin_format_editor_configure', $form_state->getSubmitHandlers())) {

then it works.

That seems like a reasonable change!

Thanks for tracking that down 😊👏

The patch from the MR. In case anyone need it to test with your site.

Sorry the #14 patch is failed to apply to 10.0.x branch.
Here is the new patch.

Committed fc024f3 and pushed to 11.x. Thanks! Cherry-picked all the way to 9.5.x since this is a non-disruptive bug fix.

Automatically closed - issue fixed for 2 weeks with no activity.

Hello. I'm reopening this issue because I'm facing a issue that seems related.

Core: 10.1.2 (also in 10.0.9 )

Steps to reproduce:

1. Open configuration page for some text format, i.e. Full HTML
2. Drag and drop Style button to active toolbar

Expected result:

- Show up a "Select Style tab" under CKEditor5 plugin settings, to be able to edit such styles.

Current result:

Nothing happen. "Select Style tab" missing.
Also, if configuration is summited, show up this error: "Enable at least one style, otherwise disable the Style plugin. "

Not sure if this could be addressed here, or a new issue should be created.

Facing same problem on Drupal 10.2.1. Any solution?

Same as #24 in 10.2, but I had to disable all filters in order to add styles.

Same problem in 10.2.5

Re-opening this.
