---------------------------------

Hi, this works fine for me

 onexpand=" var scrollOffsets = Position.realOffset(this.layer);        
                      this.layer.style.top=parseInt(this.layer.style.top) - parseInt(scrollOffsets[1])+'px';"

my all code: 
 <rich:panel id="panelFolderTree" style="border-top-width:0px; height:573px; overflow:auto; overflow-x:auto;">

 <rich:contextMenu onexpand="
                    var scrollOffsets = Position.realOffset(this.layer);        
                    this.layer.style.top=parseInt(this.layer.style.top) - parseInt(scrollOffsets[1])+'px';"
                    binding="#{appContext.dynamicComponents['folderTreeMenu']}"
                    id="folderTreeMenu" attached="false" submitMode="ajax"/>
 
 <rich:tree id="folderTree"  ....     >
   <rich:recursiveTreeNodesAdaptor ... >
     <rich:treeNode ...> 
     </rich:treeNode>
   </rich:recursiveTreeNodesAdaptor>
  </rich:tree>
</rich:panel>

> I have a lot of context menu's placed inside a scrollable div. When the scrollbar is at the top the pop up shows correctly but when I scroll down the pop up moves more towards the bottom. 
> The context menu is created as followed
> <rich:contextMenu  attached="false"
> 				   disableDefaultMenu="false"
> 				   styleClass="left"					   			   
> 				   id="contextMenu"					   					   
> 				   style="z-index:1500"					   
> 				   >		...
> And is summoned by a rich:componentControl onclick event
> <h:panelGrid columns="2">
> 	<h:outputText value="Actions" styleClass="actions" />
> 	<h:graphicImage value="#{root}/img/arrow_down.png" />	
> 	<rich:componentControl event="onclick" for="contextMenu" operation="show"></rich:componentControl>
