Output Formats

Our HtmlEditor can output the markup in HTML and Markdown formats. To specify the format, use the valueType property. If you use Markdown, import the Markdown converter as described in the valueType article.

The HtmlEditor stores the markup in the value property. In this demo, the value is displayed under the HtmlEditor. You can click the Html and Markdown buttons to switch between output formats.
