Hello, I have never created a site before so I am learning as I go, I have no idea what I’m doing so I will try to explain my train of thought as best I can 
I am hoping my question makes sense! Any help is greatly appreciated! Here is what I am looking to do…
I am creating a site that has databases of different collectibles. I have made dynamic pages for each collection so that when you click on the collection name, it takes you to a page that shows the individual items…when you click on an item, it takes you to the details page of that item.
When a member is either on the collections (all) page or the collections (item) page I want them to be able to click a button that is associated with that specific collectable and have a form pop up that will allow the member to answer a few questions about the item they personally own and then “add” it to their collection.
By add to their collection, I mean, when the user completes the form and clicks an “add to collection” button, they can then go to their member page and see a list that is specifically their collection.
Is this possible?? Any help is greatly appreciated! Thank you!
