    [CLOSED] Multicombo with partially readonly listitems

    Hi
    Is it possible to make a multicombo have some items disabled/readonly? here is an example how it should look like, it is not multicombox but a button with menu that emulates a multicombo.

     <ext:Button 
            ID="Button1" 
            runat="server" 
            Icon="Rgb" 
            Text="[Select Colors]" 
            Width="200">
            <Menu>
                <ext:Menu runat="server" Width="200">
                    <Defaults>
                        <ext:Parameter Name="HideOnClick" Value="false" Mode="Raw" />
                    </Defaults>
                    <Items>
                        <ext:CheckMenuItem runat="server" Text="Red" CheckHandler="updateButtonText" Width="194" />
                        <ext:CheckMenuItem runat="server" Text="Green" CheckHandler="updateButtonText" />
                        <ext:CheckMenuItem runat="server" Text="Blue" CheckHandler="updateButtonText" Disabled="true" Checked="true" />
                    </Items>                    
                </ext:Menu>
            </Menu>
        </ext:Button>

            new {value = 1, text = "Item 1", disabled = false},
            new {value = 2, text = "Item 2", disabled = true},
            new {value = 3, text = "Item 3", disabled = false}
