What feature must be enabled to display a Smartsheet Form on a Dashboard?

To display a Smartsheet Form on a Dashboard, the feature that must be enabled is the Web Content Widget. This widget allows you to embed various types of web content, including Smartsheet Forms, directly into your Dashboard. By utilizing the Web Content Widget, you can input the form's URL, enabling users to interact with the form seamlessly from the Dashboard interface.

Other features, such as Attachments and Images, focus on displaying files or visual content rather than interactive components like forms. Publishing is related to sharing access to sheets or reports externally but does not specifically pertain to embedding forms within Dashboards. Only the Web Content Widget is designed for this purpose, making it the essential feature needed for showing Smartsheet Forms on a Dashboard.
