Rich text fields can have custom code embedded in them (<> symbol). See the University. You basically are using it as a container to hold code since Webflow will not encode the contents. It is a workaround that works.
Thank you. I understand it can contain a code, but I don’t understand, how can I add this rich text field to the page template custom code with the +Add Field. This function doesn’t show rich-text fields. Or I shouldn’t add it there, and I can add a hidden rich-text element with this field somewhere in the body with the page designer?
I am trying to the same thing with schema.org customisation in collection settings. When I want to tie schema.org description with my custom rich text field Description by clicking +Add Field, it won’t display my rich text field in the dropdown of the the +AddField. Any work around for this, or maybe provide an answer with some steps I need to follow/do/implement?
