How to create a collapsible section in a knowledge article

[thomashansson]

We will migrate content from IBM Notes to ServiceNow KB. Lot of documents which are more than one page have collapsible sections which makes them easy to overview and read. 

Has anyone found out how to create a collapsible section in a knowledge article?

I am trying that as well. I am able to collapse/expand but it only works fine for first link and not others.

My coworker had developed this when we went into SN in 2017.  Unfortunately, it doesn't work on the Service Portal in our configuration, but it's been working in Native UI since 2017.  See the attached files for details.
