Adding Media, Videos & Callouts

Contributor

The Lexical editor includes six custom block types that make your articles more engaging and interactive. To insert any block, place your cursor at the desired location and click the "+" button in the toolbar.

Video Embed

Embed videos from YouTube or Vimeo directly into your article. PATHS does not host video files — all video content is delivered via third-party embeds.

Click the "+" button and select Video Embed.
Paste the full YouTube or Vimeo URL into the URL field (e.g., https://www.youtube.com/watch?v=...).
Optionally add a caption to describe the video content.

Use the standard watch URL for YouTube videos, not the shortened youtu.be format. The embed block will extract the video ID automatically.

Quiz Question

Add multiple-choice knowledge checks directly within your article. Quizzes help reinforce key concepts and keep learners actively engaged.

Click the "+" button and select Quiz Question.
Enter the question text in the question field.
Add at least two answer options. Click "Add Option" to add more choices.
Mark the correct answer by selecting the radio button next to it.
Optionally add an explanation that displays after the learner answers, explaining why the correct answer is right.

Quiz best practices

Write clear, unambiguous questions with one definitively correct answer. Avoid trick questions. Include 3-4 options for the best balance of challenge and usability.

Callout

Callouts are styled boxes that draw attention to important information. Four types are available:

  • Info — general supplementary information or context
  • Warning — cautions, prerequisites, or potential pitfalls
  • Tip — helpful suggestions and best practices
  • Success — positive outcomes, confirmations, or achievements
Click the "+" button and select Callout.
Choose the callout type (info, warning, tip, or success).
Write the callout content in the text area. You can use basic formatting inside callouts.

Do not overuse callouts. If everything is highlighted, nothing stands out. Reserve callouts for genuinely important points that learners should not miss.

Audio Embed

Embed podcast clips or narrated explanations. Select Audio Embed from the "+" menu, upload a file or provide a URL, and add a title.

Image Gallery

Display multiple images in a gallery layout. Select Image Gallery, upload images or choose from the Media library, and add captions.

PDF Viewer

Embed PDF documents for viewing or download. Select PDF Viewer, upload a PDF or choose from the Media library, and add a title.

Choosing the right block

Use video embeds for demonstrations, quiz questions after teaching a concept, callouts for critical reminders, and image galleries for visual evidence or processes.
