# ResponsiveHtmlPreview Resource

**Note:** Responsive Signing is disabled by default. To use this functionality, an account administrator must switch the account setting `enableResponsiveSigning` to **true.**
Also note that Smart Sections (creating a signable HTML document that uses collapsible sections and rotating tables) are premium features. To request them, contact your Docusign account manager.
