Abstract: A method for dynamically re-sizing virtual board lists during a drag and drop operation. The method includes rendering a virtual board on a display including a first list and a second list, each having list objects. The method includes storing a total size of the first list and second list, and sizes of list objects in the first list and the second list in a corresponding first list cache and second list cache; detecting selection and movement of a list object from the first list to the second list; adding the size of the selected list object to the second list cache; and rendering and displaying a placeholder area of the selected list object, the placeholder area having the same size as the size of the selected list object, and displaying an increased size of the second list based on the updated total size of the second list.
