I hope someone can help me
Is this for the SaaS product or the PaaS/OnPrem product? What I see is a question/answer combination. On our PaaS/Prem product you could install the FAQ feature which has something for this, but the backend is just basically a question/answer pair. How the frontend behaves is up to the implementation, especially in a headless implementation. There is a ftl implementation available, but even that is just for reference.
For SaaS you just need to create a document that has question/answer pairs. There are many ways you could possibly implement this, depending on your use case.
