Dynamically Calculate "Set Position" about vue-my-dropdown

[aphofstede]

I think @zanematthew meant:
It would be nice to be able to clamp the dropdown to the window edges. (Don't render outside the visible canvas, regardless of :position prop)

e.g.

// around line 89
  switch (p3) {
    ...
    default:
      outStyle.left = Math.max(Math.round(cornerPos.left - dpSize.width), 0) // don't go beyond left edge
      origin.left = 'right'
  }
