Link Button to CMS - To open sidebar for specific collection item

I am working on a sample website for a fake coffee company. I am using a CMS with the coffee blend in a grid. When you click each coffee a sidebar opens with more information about that coffee blend.

I have created the sidebar and all works fine when working with only one item visible in the CMS grid. But when I have multiple products in the CMS grid and I select the ‘find out more button’ it opens the sidebar but seems to only open one collection item rather than the specific item that you select.

I basically need to link the button to the collection somehow so it opens each one and then the information for the one clicked shows up in the sidebar.

ANy ideas on how to do this? ( I cannot code btw so if code is needed I would appreciate the help)
