Hello, The code : http://codepen.io/hemels/pen/WQGqLB I'm working on project with draggable and works perfect, BUT i cant get one thing working. After you drag a div over a grid of divs the draggable div is append to the cell from the grid. This works fine. But when you drag the div for the second time, the div has to be 'de'-preppend (works) only its on the wrong position. I guess its the transform that needs to be reset. But what ever i try i cant get the result i want. There must be a simple sollution somehow, but after 2 hours of try and error i ask... Thanks for the great software and the support ! gr Mels
