So in my game i need a panel that I can drag it down with touch. So its kind like how items are placed in a grid where the user is able to scroll through the list with the mouse by clicking it and dragging the items in the grid . I need my panel to be able to spring down when i click on it and drag it down and when i swipe it up the panel will then spring back to the top where the user cant see the menu anymore.
BTW this game is for an iphone, any suggestions how i can approach this sort of behavior.
