Dynamic MenuItems as Checkboxes

[Jerome]

I'm trying to create a menu such that the second level items are checkboxes and added programmaticly.
Here is what I would like to create, an options menu such that it shows it show Export and Columns.  Then Columns will show the checkbox items which need to be created dynamically.

Options
 - Export
 - Columns
   -- CheckBox Item 1
   -- CheckBox Item 2

Hello Jerome,

You should use templates in order to have checkboxes in the menu items. Here is explained how to add templates dynamically.

The link that you provided was a great help in how to use the templates.  I am able to add menu items to the first level menu, what I need is to add menu items to a level 1 menu item so that the new menu items are level 2 menu items.  Here is the code that I'm using in the page load event to try adding level 2 menu items.

 foreach (RadMenuItem menuItem in this.RadMenuOptionsColumns.Items)
                {
                    if (menuItem.Items.Count > 0)
                    {
                        //find the level 1 menu item that we want to add items under.
                        foreach (RadMenuItem nestMenuItem in menuItem.Items)
                        {
                            if (nestMenuItem.Value == "columns")
                            {

                                //Clear any old menu items
                                nestMenuItem.Items.Clear();

                                foreach (string column in view.Columns)
                                {
                                    RadMenuItem item = new RadMenuItem(column);
                                    item.ItemTemplate = new CheckBoxTemplate();

                                    nestMenuItem.Items.Add(item);
                                }

                                nestMenuItem.DataBind();
                                break;
                            }
                        }
                    }
                }

                this.RadMenuOptionsColumns.DataBind();
