Hi,

Currently it is not possible to control this out of the box. Implementation is here: http://fisheye.jboss.org/browse/RichFaces/trunk/ui/tree/src/main/resources/org/richfaces/renderkit/html/scripts/tree.js?r=12086 - lines 219 - 234

Hi,

you can control it with java script.

function setScrollHeight(){
var scroll = document.getElementById('the:element');
var scroll_higher = scroll.scrollTop + 400;
scroll.scrollTop = scroll_higher;
}

I used a similar approach:

See line 9.  Thanks for the tip.

<rich:treeNode 
  type="branch"
  toggleListener="#{itemCategoryController.processTreeToggle}"
  expanded="#{node.expanded}"
  rendered="#{!node.hide}"
  iconExpanded="/resources/default/1_0/img/tree/Folder.gif"
  iconCollapsed="/resources/default/1_0/img/tree/Folder.gif"
  ondblclick="#{mnat:concat(popUpId,'PrcBrnchSel()')}"
  ontoggle="this.scrollIntoView(true);">
 #{node.category.categoryName}
</rich:treeNode>
