If Drag Layer is unavailable, you probably have a layer selected. For pop-up menu. 4 Select the layer that you want to make draggable from the Layer pop-up menu. 5 Select either Constrained or Unconstrained from the Movement pop-up menu. For slider controls and moveable scenery such as file drawers, curtains, and mini-blinds, choose constrained movement.
Values are relative to the starting position of the layer.
To constrain movement within a rectangular region, enter positive values in all four fields. To allow only vertical movement, enter positive values for Up and Down and 0 for Left and Right. To allow only horizontal movement, enter positive values for Left and Right and 0 for Up and Down. The drop target is the spot to which you want the user to drag the layer. A layer is considered to have reached the drop target when its left and top coordinates match the values you enter in the Left and Top fields.
