Making menu dynamic

[andrewwilkin]

I desperately wanted to use this library to create a menu system, the biggest blocker for me is being able to create dynamic menus that can add and remove options, and those menus act on an instance of an object to interact with it.

For example a menu system that allowed you to select a file from a directory listing and work with it. Ideas?

A simple -probably not the best- solution would be to add the following to your Input.cs:

public static string ReadList(string prompt, List<string> items)
{
    Output.WriteLine(prompt);
    var menu = new Menu();

    var choice = string.Empty;

    foreach (var value in items)
        menu.Add(value, () => { choice = value; });

    menu.Display();

    return choice;
}

Thanks. I used the code as a starting point, and opened up the permissions to allow me to extend the behaviour.

Ultimately the approach I took was overriding the Display method, which allowed me to change the page title, add options etc.

Something like this:

        public override void Display()
        {
            Menu = new Menu();
            foreach (var environment in _registryEngine.Environments.OrderBy(x => x.Order))
            {
                Menu.Add($"{environment.Name} ({environment.ApiUrl})", () =>
                {
                    _registryEngine.SetEnvironment(environment.Name);
                    Program.NavigateHome();
                });
            }

            base.Display();
        }
