I am looking for a way to add expandable /collapsible text to Knowledge Articles. I am unable to use the HTML5 <details> tag as it does not work in IE. Has anyone found a way to do this without editing the kb_view UI page?
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.
