Check carefully for the width of your ul after the ul is empty And when your ul is empty there is no width and as a result, you cannot drop li over it. You can check the width of ul by applying a border. The solution is only applied width to your all ul and the problem will be sorted. eg: .droptrue{width: 100%} (.droptrue is my ul)
