end

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.

Options

: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.
[:data][:direct_upload_url] - Defaults to rails_direct_uploads_url.
[:data][:blob_url_template] - Defaults to rails_service_blob_url(":signed_id", ":filename").

Example

rich_text_area_tag "content", message.content
# <input type="hidden" name="content" id="trix_input_post_1">
# <trix-editor id="content" input="trix_input_post_1" class="trix-content" ...></trix-editor>
