Linking a static 'link block' element to CMS Collection Data

Hey everyone. I’ve been trying to figure out how I can get a static link block element to connect somehow to CMS Collection data. In a nutshell, when a user hovers over each dot in my interactive map, I want a card to appear (this works using interactions) but I want the content in the card to be dynamic, ie. linking to the specific dot I’m hovering over. I have a feeling I need to be using custom attributes to do this but I don’t know enough about these. I have however, labelled each of these dots with it’s own unique custom attribute as an identifier.
Any help much appreciated, TIA!

Hi Julia, here’s one approach.
You can put the modals inside of the collection list so that each of them has the correct collection item data.

Thanks so much for the tip. This solution will work, and I guess I will need to add a CMS filter in as a custom attribute to ensure the dot links then filters to the correct collection item?
