[antoreegan]

This is my asp.net snippet

 <ext:FormPanel ID="FormContTemplate" runat="server" Frame="true" Cls="bordernone">
        <Items>
            <ext:Container ID="ContTemplate" runat="server">
            </ext:Container>
        </Items>
    </ext:FormPanel>

this is my C# snippet

        Container container = new Container();
        Ext.Net.DropDownField combo = new Ext.Net.DropDownField();
        combo.ID = "CompoTemplate" + 1;
        combo.IndicatorCls = "red-text";

        Ext.Net.Panel panel = new Ext.Net.Panel();
        panel.ID = "Panel1";
        panel.Height = 200;
        panel.Layout = "Accordian";

        Ext.Net.MenuPanel menuPanel = new Ext.Net.MenuPanel();
        menuPanel.ID = "MenuPanel1";

        Ext.Net.Menu menu = new Ext.Net.Menu();
        menu.ID = "Menu1";

        Ext.Net.MenuItem menuItem1 = new Ext.Net.MenuItem();
        Ext.Net.MenuItem menuItem2 = new Ext.Net.MenuItem();
        Ext.Net.MenuItem menuItem3 = new Ext.Net.MenuItem();

        menu.Items.Add(menuItem1);
        menu.Items.Add(menuItem2);
        menu.Items.Add(menuItem3);

        menuPanel.Add(menu);

        panel.Items.Add(menuPanel);

        combo.ContentContainer.Controls.Add(panel);

        container.Items.Add(combo);

Solved danill

I tried to add accordian in dropdown field

now i solved that problem.

my mistake is

combo.ContentContainer.Controls.Add(panel);

the right one

combo.Component.Add(panel);

My code

  Ext.Net.Container container = new Ext.Net.Container();
        Ext.Net.DropDownField combo = new Ext.Net.DropDownField();
        combo.ID = "CompoTemplate" + 1;
        combo.IndicatorCls = "red-text";


        Ext.Net.Panel panel = new Ext.Net.Panel();
        panel.ID = "Panel1";
        panel.Height = 200;
        panel.Layout = LayoutType.Accordion.ToString();

        Ext.Net.MenuPanel menuPanel = new Ext.Net.MenuPanel();
        menuPanel.ID = "MenuPanel1";

        Ext.Net.Menu menu = new Ext.Net.Menu();
        menu.ID = "Menu1";

        Ext.Net.MenuItem menuItem1 = new Ext.Net.MenuItem();
        Ext.Net.MenuItem menuItem2 = new Ext.Net.MenuItem();
        Ext.Net.MenuItem menuItem3 = new Ext.Net.MenuItem();

        menuItem1.Text = "1";
        menuItem2.Text = "2";
        menuItem3.Text = "3";

        menuPanel.Menu.Items.Add(menuItem1);
        menuPanel.Menu.Items.Add(menuItem2);
        menuPanel.Menu.Items.Add(menuItem3);

        panel.Items.Add(menuPanel);

        combo.Component.Add(panel);

        container.Items.Add(combo);
        ContTemplate.Items.Add(container);

 <ext:FormPanel ID="FormContTemplate" runat="server" Frame="true" Cls="bordernone">
        <Items>
            <ext:Container ID="ContTemplate" runat="server">
            </ext:Container>
        </Items>
    </ext:FormPanel>
