How do I fix this menu system [PLEASE HELP]

So working on my game in CS2, I need a scrolling box for the menu system. I've read a bunch of useless tuts either barely explaining what to do, how it works and how to accomplish this with sprites. Not text boxes. So if someone could please help me that would be great

Here's what I'm trying to accomplish:



I want to add multiple items to the player's inventory system while being able to be dragged down.

How would I do so? Any help is appreciated and I'm also kinda noobish when it comes to CS2, but I know most Beginner and Intermediate stuff.

you can pin your sprites at various points to a larger sprite then use drag and drop to scroll up and down.
