I need to use a rich text editor on a web application. I've chosen Toast UI editor: .editor/latest/.

The application is developed in python using cherrypy. My forms are managed using WTForms.

I can't understand how to create a custom widget in WTForms based on the TUI Editor. More generally speaking, the problem is to use WTForms on 3rd party "complex" web widgets.

Can you help me?

Thanks a lot!
