I have a body field (Text field with summary) with WYSIWYG CKeditor enabled.
However, the "summary" part of the field lacks a WYSIWYG editor.
How can I enable it?
Under your content type -> manage fields for the summary field you can enable text processing to be filtered text (user selects input format). Hope that helps.
I had created my own summary field in CCK. I use the CKeditor and this only worked after I realised I had to configure the field as a multiline text area and not as a single line text field.
I just tried WYSIWYG module version 7.x-2.x-dev with CKEditor (the editor, not the Drupal module), and it actually worked -- the summary field now displays with a wysiwyg editor instead of the plain textarea.
If you are using the wysiwyg module you can enable/disable this in the wysiwyg profile settings. It’s in the fieldset at the bottom: «Basic settings - Enable on summary fields».
