The horizontal screen coordinate of the visual stimulus where stimuli that are dragged and dropped onto it are positioned.
<button> <clock> <picture> <shape> <text> <video>
This property allows a script to get or set the horizontal position on the stimulus where dragged and dropped items are positioned. The coordinate can be specified in pixels or percents.
The following sets the drop position of a drop target to the upper left corner of the stimulus:
<trial example>
/ ontrialbegin = [shape.dropoption1.dropy = 10%; shape.dropoption1.dropy = 10%;]
</trial>
