- It is actually using the textareamimetypeselector pattern. i'm not
sure you want that for anon. I'm not very familiar with the details of
the pattern. I think this is a bit complicated in how it integrates with
z3c form and the pattern.
OK, I'm looking over the rich text widget. All the docs I've found use plone.app.textfield.RichText, which is what is using the textareamimetypeselector. pattern. I switched the fields to use plone.app.z3cform.wysiwyg.WysiwygFieldWidget, which works with the JS you had originally suggested, but there is a deprecation warning that it will be removed in Plone 5.1.
What widget do you recommend using?
