Setting up Jelly fin collections

[Enquiries]

I am trying to set up collections of movies or TV shows that have seasons or episodes. For example, I am trying to organize Jessie Stone shows. There are 9 Jessie Stone shows and I would like to see one poster with the episodes displayed after I click on it. I read the Jellyfin help documents, but it doesn't seem to work for me. Can you help?

Thanks
