Hi,

This widget is not (yet? ;-)) exposed in Studio, but you can still use it. Here are the requirements:

• Two fields are needed in the schema:
• One (String) to store the content
• and another (String) to store the mime-type (html, markdown, …)
• Using a “Generic” widget and forcing the name to richtext_with_mimetype

So, say you have the MyDocType document, with a schema prefix mdt and two fields, details and details_mimetype. In your layout, drop a “Generic” widget and:

• Click “Add field”, enter met:details (the list of fields is ordered, first one must be the storage field)
• Click “add field” again and enter met:details_mimetype
• As “Widget type”, enter richtext_with_mimetype
• (save. Of course :-))

I owe a big thanks to Anahide who helped me a lot on this answer :-)
