Ckeditor 5 is wrapping html tags inside p tag

I feel like this may already have been asked.

Hi cilefan, Could you please replicate the issue.These issues were not there in ckeditor4.

Hi Someone ,can please check. This is issue is impacting our whole site after migration to cke5editor from ckeditor4

Hi @Drupalite1411,
Did you manage to resolve this? I have the same problem

Please find out if this is a CKEditor behavior or a Drupal integration or filter. Use https://ckeditor.com/ckeditor-5/demo/

@torresrecife No I am still using ckeditor 4 due to this issue.

Moving to CKEditor5 component. The component 'ckeditor.module' refers to CKEditor 4, it was the simplest way to distinguish them when they were both in core.

@cilefen, this definitely is a CKeditor behavior. To get some context, why that happens in CKeditor5, please read https://github.com/ckeditor/ckeditor5/issues/16203.

Some support from the Drupal Core team there might be helpful.

checked in drupal 11, CKEditor5 automatically adds paragraph tags to elements. Currently, this issue cannot be resolved without an update from the CKEditor 5 maintainers.

NOTE: Pasting into ckeditor5 works on their website without it adding the extra wrapping p tag: https://ckeditor.com/docs/ckeditor5/latest/examples/builds-custom/full-f...

Given that, this is something we should be able to fix in drupal...

I'm still seeing the issue at the link from emanaton.

From the Source view, enter this outside any other element:
<span class="test">test</span>

Click Save and it turns into:

<p>
  <span class="test">test</span>
</p>

Same problem here. For example, if you add a dl-list:

<dl>
    <dt>Some text</dt>
    <dd>Some text too</dd>
</dl>

Will result in this after saving:

<dl>
    <dt><p>Some text</p></dt>
    <dd><p>Some text too</p></dd>
</dl>

I tried it with all format filter unchecked (/admin/config/content/formats/manage/full) , and with the filters like html corrector, newline
etc. on = same result.

Some simila issues:

Workaround for specific cases:

/**
 * Implements hook_preprocess_HOOK().
 */
function THEME_preprocess_TEMPLATENAME(&$variables) {
  // Remove the <p>tags inside <dt> and <dd> tags.
  if ($text = $variables['items'][0]['content']['#text']??NULL) {
    if (str_contains($text, '<dt')) {
      $result = preg_replace(
        pattern: '#<(dt|dd)\s*>\s*<p>(.*?)</p>\s*</\1>#si',
        replacement: '<$1>$2</$1>',
        subject: $text
      );
      $variables['items'][0]['content']['#text'] = $result;
    }
  }
}

But be careful, for complex scenarios you go better with the DOM-API.
