I have been trying to write a money drop function in single player using scripthookVdotnet and NativeUI. I cant for the life of me figure this out. I have tried rewriting it in multiple ways. The problem is if i don't use a loop it only drops once. When i do loop, it doesn't stop dropping and I cant open the menu again for some reason. So what i'm really trying to do is open the menu while its dropping so i could possibly stop it.

void DropMoney()
        {
            var moneyDrop = new UIMenuCheckboxItem("Money Drop", ketchup, "This took wayy too long.");
            moneyMenu.AddItem(moneyDrop);
            moneyMenu.OnCheckboxChange += (sender, item, checked_) =>
            {
                if (item == moneyDrop)
                {
                    DropFunction(true);
                }
            };
        }

public void DropFunction(bool dropTrue)
        {

            while (dropTrue)
            {
                UI.ShowSubtitle("Dropped money");
                int money_bag = Function.Call<int>(Hash.GET_HASH_KEY, "prop_money_bag_01");
                int pickup_title = Function.Call<int>(Hash.GET_HASH_KEY, "PICKUP_MONEY_CASE");
                Vector3 dropPos = Game.Player.Character.GetOffsetInWorldCoords(new Vector3(0f, 0f, 2f));
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);
                Function.Call(Hash.CREATE_AMBIENT_PICKUP, pickup_title, dropPos.X, dropPos.Y, dropPos.Z, 0, 200000, money_bag, false, true);

                Wait(200);

            }
        }
