data-gs-animate: turns animation on (for grid)
data-gs-column: amount of columns (for grid)
data-gs-max-row: maximum rows amount, defaults to 0 (for grid)
data-gs-current-height: current rows amount (for grid)
data-gs-id: unique ID (for item)
data-gs-x, data-gs-y: element position (for item)
data-gs-width, data-gs-height: element size (for item)
data-gs-max-width, data-gs-min-width, data-gs-max-height,data-gs-min-height: element constraints (for item)
data-gs-no-resize: disable element resizing (for item)
data-gs-no-move: disable element moving (for item)
data-gs-auto-position: tells to ignore data-gs-x and data-gs-y attributes and to place element to the first available position (for item)
data-gs-locked: the widget will be locked. It means another widgets couldn't move it during dragging or resizing. The widget is still can be dragged or resized. You need to add data-gs-no-resize and data-gs-no-move attributes to completely lock the widget (for item)
data-gs-resize-handles: resize handles (for item)
