The top right is the child and the bottom left is the parent

I want it so that if the top right or middle is dragged it doesn't move, but if the bottom left is dragged it does move

I've tried a ton of combinations of Draggable and Active and none of them seem to work. I think there's a simpler way than having it start dragging using MouseButton1 and end dragging when it's lefted but I can't figure out how
