+Widgets of smaller or equal size to the dragged widget (player) +will swap places with the original widget. + +This causes tiles to swap left and right as well as up and down. + +By default smaller players will shift larger widgets down. + +I have added an option to prevent this behavior: + + $.gridster({ + shift_larger_widgets_down: false + }); + +By setting shift_larger_widgets_down to false,
