Hi Luis,
I have read all the other threads on CMS nest in this forum and watched the videos. I cannot figure out why my Nest implementation is not working.
Can you please take a look

Hey @peacock! You are missing the fs-cmsnest-element = list attribute on your list. I also see you are hiding the child list directly on the designer, we recommend using a div wrapper set to display: none as this might also cause the solution to break.
The template page appears to be correctly setup so the above changes should be enough to have a working implementation.
Let me know how it goes! 
Ah man, I had a list defined for the filter and not the nest. And yes, my direct hides were also impacting it. Thanks for your help Luis.
