"Draggable" Drag vertical only?

Question

I have this page that prompts you to drag it upwards to reveal the actual page. I want to know if there's any option so that you only can drag it vertically (Y-axis) i.e. "up". Is there any way to do this?

Answer 1

Yes, this is possible.

$( "#draggable" ).draggable({ axis: "y" });
