Collection inside accordion

Hello, I am trying to combine the collection-repeat type of view with accordion expandable list…

Basically combining this and this

It does not seem to work…

How can I go about it? Thank you!

I think that you can’t use multiple collection-repeats on the same page (which is what you are trying to do); e.g. Collection-repeat throwing error when using multiple lists

Thank you, @dansharp. I guess I can solve it with this gallery method then?

Do you found any work around for this?
