I want to embed content from an external source on the internet. Which interface component is best suited for this scenario?

The best interface component for embedding content from an external source on the internet is the Web Content component. This component is specifically designed to render web pages or any other external HTML content directly within an Appian interface. By using the Web Content component, you can specify a URL from which the content will be retrieved and displayed, allowing users to interact with that external content seamlessly within the Appian application.

This capability to embed live content directly from the web enhances user experience and facilitates the integration of various web services or resources without leaving the Appian platform. It supports a wide range of content types, including documents, videos, and interactive web applications.

Other options like the Document Viewer are meant for displaying documents uploaded within Appian rather than content from external URLs. The Interface Grid is tailored for displaying structured data in a table format, and the Text Area is primarily for entering or displaying plain text, making them unsuitable for embedding external content.
