Single Accordion with Multiple Collapsible Sections

[gingw]

Hi @ejbenke - Hope you are doing well. Thank you for your help on the Collapsible/Expandable Webpart Title last year which is working great.

I'm looking at having the accordion Webpart to be able to have a second subtitle to be entered to create multiple collapsible sections in the accordion. So it will have three levels where the first level is the Title, the second level to be another Title (subtitle), and the third level will pull the content from the SP list. Pictured below.

I tried several days to figure out the code but wasn't successfully.

Any help with this would be great.

Thank you for all your help and looking forward to hearing from you.
