Multiple panels in the same side

[rrfranco92]

Hey,
nice library!

Do you think is possible dooing something like this?

I was using your example of nested panels but when defining the width/distanceX of each panel, it is relative to the parent panel and I need it to be relative to the size of document, in my case 1024px.

I tried changing the distanceX of the level 1 panel using beforePanelOpen when opening level 2 panel but it is not working..

Any advice?
