I am trying to create collapsible content in a knowledge base article and it appears that the following HTML attributes are being stripped on rendering the article: data-toggle and id.
Per this article: https://solutions.teamdynamix.com/TDClient/KB/ArticleDet?ID=6392 , it does not state that any HTML attributes are being filtered. Is this expected behavior? It would be really helpful to atleast have data-toggle available. Then you can use CSS classes to target items to collapse.
