First, very nice plugin.


I try to use GSAP draggable with the "autoscroll" option, but there is a problem when I scroll down a tile the position is not correctly updated.


You can check in the following codepen demo :


It's seems to me the problem come from the "position:absolute" in the .st-menu CSS style.

If i remove this property the draggable autoscroll seems to work better.


But i can't remove this attribute in my site because it broke my menu.


Is there a workaround for this issue with the autoscroll option ?


Thank you.


Keep up the good work.

It looks to me like the problem had to do with the fact that you were creating your Draggable BEFORE you added your element to the DOM, so when Draggable tried to add its "scroll" listeners to all the ancestor elements, none existed. So if you can either:

  • Create your Draggable after you've added your element to the DOM
  • -OR- just disable() and then enable() the Draggable instance to trigger it to add the scroll listeners again (of course do this after you've added it to the DOM). 

Does that help? 


FYI, we'll be releasing a minor update to Draggable very soon which you can preview (uncompressed) at https://s3-us-west-2.amazonaws.com/s.cdpn.io/16327/Draggable-latest-beta.js
