I know this is a bit of a stretch, but I have been building this small React application that includes creating, editing and deleting these draggable cards. I now want to make some type of a system where I can create a list that holds those cards, so that I could possibly track their completeness that way. The issue is - I experimented with some placeholders, but the problem is I have not too much knowledge on how to approach this problem. Any advice (using React JS) would be greatly appreciated!

I tried creating the list functionality, but unfortunately I can't get it to work at all. I am not asking for a full on solution, but maybe advice on how to somehow target this problem! :)
