Performance issue

[samuus]

Hello

We are trying to implement Xonomy in our website.

But we encounter a perfomance issue on IE11 and Edge :

As you can see on our test page « Test2.html», it’s difficult to expand/collapse Xml

With profiler tool (F12), we can see that action "event" seems take long time : we are under the impression that jQuery animation (fadeIn,slideUp) is part of the issue.

Any advice to optimize our code ?

Is it possible to create an option to disable animation ?

Best regards

We have found an explanation :
We think that part of the issue is in xonomy.css.
If we delete this class: .xonomy.nerd * { position: relative; }, performance problem solved in IE11 and Edge.
But there are some impacts :

1)plus/minus issue : modify this class :
.xonomy.nerd .element .connector :{ border-top: 1px dotted #b6b6b6; width: 24px; height: 10px; position: relative; top: 9px; left: -10px; }

2. Chewed selectable text issue : modify this class :
   .xonomy.nerd .element > .children > .textnode .char { position : relative;}
   with this last modification, performance issue reappears a little.

Maybe, InlineMenu could be restructured without using a "position:relative" ?
