HI,

Thanks for your reply much appreciated.

I tried your code and it throws an 'object doesnt support this property or method' error on the lines:-

if (nodes.Id != nodeId)
       nodes.setExpanded(false);

any suggestions please?

thanks again

regards,
onan.

HI onan,

What version of NetAdvantage are you using. This javascript function was tested with 7.3.1043. It works

function UltraWebTree1_NodeExpand(treeId, nodeId){
 //Add code to handle your event here.
 
 //Add code to handle your event here.
 // debugger;
 var node = igtree_getNodeById(nodeId);
 var tree = igtree_getTreeById(treeId);
 var level = node.getLevel();
 if (level == 0)
 {
    
     var nodes =  tree.getNodes();
     for (var i = 0; i < nodes.length; i++)
     {
       if (nodes.Id != nodeId)
       nodes.setExpanded(false);
     }
 
 
 
// node.setExpanded(true);
 

}
}
