rich_text_area_tag(name, value = nil, options = {})

Returns a trix-editor tag that instantiates the Trix JavaScript editor as well as a hidden field that Trix will write to on changes, so the content will be sent on form submissions.


  • :class - Defaults to “trix-content” so that default styles will be applied. Setting this to a different value will prevent default styles from being applied.
