jQuery/JS Common - Object Structures - positionConfig - boundaryOffset
Specifies the offset of boundaries from the boundary element.
The offset is specified in pixels. To set this property, use an object with the x and y fields. These fields specify horizontal and vertical offsets, respectively. Alternatively, you can use a string value that indicates the offsets separated by a whitespace character. A positive offset narrows the boundaries; a negative offset widens the boundaries.
In the following code, left and right boundaries are narrowed (x is 50), but top and bottom boundaries are widened (y is -50).
