Hi Everyone,

I want to implement a feature in ServiceNow Knowledge Articles where when a user hovers over a hyperlink in the article body, a preview popup shows a summary or snippet of the linked content.

 

Could someone please guide me on how to implement this?

  • Should I modify the Knowledge Article?

  • How can I safely fetch and display the preview content?

  • Are there any recommended APIs or best practices for this kind of hover preview?

Thanks in advance for your help!
