        .Add("Sub_One", () => SomeAction("Sub_One"))
        .Add("Sub_Two", () => SomeAction("Sub_Two"))

		.Configure(config =>
        {
          config.Selector = "--> ";
          config.EnableFilter = true;
          config.Title = "Submenu";
          config.EnableBreadcrumb = true;
          config.WriteBreadcrumbAction = titles => Console.WriteLine(string.Join(" / ", titles));
        });
        
      var menu = new ConsoleMenu(args, level: 0)
        .Add("One", () => SomeAction("One"))
        .Add("Two", () => SomeAction("Two"))
        .Add("Three", () => SomeAction("Three"))
        .Add("Sub", subMenu.Show)
        .Add("Change me", (thisMenu) => thisMenu.CurrentItem.Name = "I am changed!")
        .Add("Close", ConsoleMenu.Close)
        .Add("Action then Close", (thisMenu) => { SomeAction("Close"); thisMenu.CloseMenu(); })
        .Add("Exit", () => Environment.Exit(0))
        .Configure(config =>
        {
          config.Selector = "--> ";
          config.EnableFilter = true;
          config.Title = "Main menu";
          config.EnableWriteTitle = true;
          config.EnableBreadcrumb = true;
        });

      menu.Show();

Running app from console with pre-selected menu items

To do this, use public ConsoleMenu(string[] args, int level) constructor during initialization. Use double quotes for item names and digits for item numbers. Here are some examples:

--menu-select=0.1                      //run first at level 0 and second at level 1
--menu-select="Sub.Sub_One.'Close...'" //run "Sub" at level 0 and "Sub_One" at level 1, and "Close..." at level 2
--menu-select="Sub.2"                  //run item "Sub" at level 0, and then run third item at level 1

Configuration

You can also define configuration via .Configure() method. The default config looks like:

  public class MenuConfig
  {
    public ConsoleColor SelectedItemBackgroundColor = Console.ForegroundColor;
    public ConsoleColor SelectedItemForegroundColor = Console.BackgroundColor;
    public ConsoleColor ItemBackgroundColor = Console.BackgroundColor;
    public ConsoleColor ItemForegroundColor = Console.ForegroundColor;
    public Action WriteHeaderAction = () => Console.WriteLine("Pick an option:");
    public Action<MenuItem> WriteItemAction = item => Console.Write("[{0}] {1}", item.Index, item.Name);
    public string Selector = ">> ";
    public string FilterPrompt = "Filter: ";
    public bool ClearConsole = true;
    public bool EnableFilter = false;
    public string ArgsPreselectedItemsKey = "--menu-select=";
    public char ArgsPreselectedItemsValueSeparator = '.';
    public bool EnableWriteTitle = false;
    public string Title = "My menu";
    public Action<string> WriteTitleAction = title => Console.WriteLine(title);
    public bool EnableBreadcrumb = false;
    public Action<IReadOnlyList<string>> WriteBreadcrumbAction = titles => Console.WriteLine(string.Join(" > ", titles));
  }

Example:

      new ConsoleMenu()
        .Add("One", () => SomeAction("One"))
        .Add("Two", () => SomeAction("Two"))
        .Add("Close", ConsoleMenu.Close)
        .Configure(config => { config.Selector = "--> "; })
        .Show();
