[sant3]

Hi to all,

is it possible to create in StartMenu/ToolConfig menuItem with sub level?

I've tried this, there is no error, but sub level menuItem will not created...

<ToolConfig>
                <ext:Toolbar runat="server">
                    <Items>
                        <ext:MenuItem Text="first level" Icon="Wrench" MenuAlign="right" HideOnClick="false" Handler="debugger;">
                            <Menu>
                                <ext:Menu ID="Menu4" runat="server">
                                    <Items>
                                           <ext:MenuItem Text="sub level"></ext:MenuItem>
                                     </Items>
                                </ext:Menu>
                            </Menu>
                          </ext:MenuItem>
