dropdown animation set to false but not working

[Tirumalesh]

i used write this: 
  var lpDpt = $("#LpDepth").kendoDropDownList({
                optionLabel: "--Select--",
                dataTextField: "Depth",
                dataValueField: "Depth",
                index: 0,
                dataSource: dsLpDpt,
                animation: false ,
                change: function () {
                    var value = this.value();
                }
            }).data("kendoDropDownList");

but still i'm getting animation. i followed this :http://www.kendoui.com/forums/ui/tabstrip/setting-tab-animation.aspx
if i used the old version js files i'm getting no effects and optional label not displaying so upgraded to latest "kendoui.complete.2012.1.322.trial", then i'm getting optional label and effects by default,i want to disable effects by animation set to 'false' but this was not working.
