Mixitup for two collection lists

So @sabanna 's tutorial for mixitup is working great, but it seems only for one collection list. When I duplicate the collection list, it only filters the first, not the second. How to deal with this?

Thanks

You’ll need additional custom code to move all items into one collection list before calling mixitup.

Thank you @samliew. It worked!

@samliew Are you able the share the additional custom code solution for this?
Many thanks. Matt
