{
    //on click the ">" button
    if(ONODETYPE_BROWSECOMBO == nEvent && lstrcmpi(lpcszNodeName,"test") == 0)
    { 
	//show a menu
    	Menu myMenu;
    	myMenu.Add("Item1", 1, MF_STRING);
    	myMenu.Add("Item2", 2, MF_STRING);
    	
    	int nSelCmd;
	POINT pt;
	GetCursorPos(&pt);
	myMenu.TrackPopupMenu(0, pt.x, pt.y, getNContainer.GetSafeHwnd(), &nSelCmd);
	if(nSelCmd > 0)
	{
		string strName;
		myMenu.GetMenuString(nSelCmd, strName, MF_STRING);
		tr.test.strVal = strName;
	}
    }
