❔ C# WPF ListView - How do you create expanded info on selection of a ListView Element?

I'm new to WPF and have decided to learn by creating a little tracker for the game Escape From Tarkov. I currently have a List of Tasks that I want to be able to select which in turn expands to an additional list of info. (I've posted the desired outcome and what I currently have) I'm not worried about styling just yet, I'm more concerned on the UI and how I can go about it. Any assistance or advice would be appreciated and if you have any questions or info you need to know and I'll get that across asap. Thanks 😄
