I did it so.

I have td as label with selected value, show hide button and div with the tree.

I am not sure how to intelligently hide the div when one cliks outside the div.

        document.onclick = doc_onclick;

        function doc_onclick()

        {

            var evt = window.event;

            if (evt.srcElement.id != "MyTreeCombo_tdLabel" &&

                evt.srcElement.id != "MyTreeCombo_imgShowHide") 

            {

                var divSHele = document.getElementById("MyTreeCombo_divDataContainer");

                if (divSHele.style.visibility == "visible")

                    divSHele.style.visibility = "hidden";

            }

        }        

        function MyTreeCombo_tree_NodeCollapse(treeId, nodeId)

        {

            var evt = window.event;

            evt.cancelBubble = true;

        }

        function MyTreeCombo_tree_NodeExpand(treeId, nodeId)

        {

            var evt = window.event;

            evt.cancelBubble = true;

        }

It's also fairly easy to put a tree in a div and have a show/hide button. Absolutely position the div and grab the "dropdown button" images from the infragistics image directory...but i'm guessing the WebDropDown is basically that anyway.

I can send you a project with my code in it if you need it. I required the same functionality in a project that uses 2008 volume 1...

version 20091

I would like the same as here :
