Embed

H5P equivalent

H5P Iframe Embedder

When to use

Use Embed for sandboxed third-party content — external tools, legacy pages, or partner widgets that must stay in an iframe.

Configure config.embed.allowedHosts in production so only approved origins load.

Requirements

  • Always set a descriptive title for screen readers.

  • Optional allow sandbox tokens and aspectRatio for layout.

Try it

Documentation demo

Use the Live demo, React, AI prompt, and Packaging / Manifest tabs below. Embedded demos disable telemetry, xAPI, and the LMS bridge. For production delivery, use the CLI template src/courseConfig.ts and LMS Go-Live.

Open demo in full tab 

<Text>Allowlist embed hosts in production course config.</Text>
<Embed blockId="policy-embed" src="https://approved.example.com/widget" title="Policy lookup" />

Copy into Cursor, Copilot, or ChatGPT after the vibe coding starter context:

Read lessonkit.json and src/App.tsx before editing.

Add a Embed block (H5P-style: Iframe Embedder) like this example inside the active <Lesson>:

<Text>Allowlist embed hosts in production course config.</Text>
<Embed blockId="policy-embed" src="https://approved.example.com/widget" title="Policy lookup" />

Requirements:
- Import only from @lessonkit/react; use block types from block-catalog.v3.json.
- Keep existing courseId, lessonId, and navigation stable unless I ask to add a lesson.
- After edits, list changed files and what to verify in the browser (lessonkit dev).
