Hi PointC, Thank you for your reply and it does work. I am wondering when will the new version be released officially and is the beta version stable for productions? Thank you again!
I set the draggable to horizontal move (type: 'x') for a svg slider button. Sometimes while mouse was moving, the button kept staying at the same location. The vertical drag(type: 'y') worked just fine. You could see the test in Codepen link. Does anybody have any ideas about that?
