Return group in SelectionPrompt and MultiSelectionPrompt

Is your feature request related to a problem? Please describe. I would love when using SelectionPrompt or MultiSelectionPrompt with choice groups, that I could get both the selected item, but also the group it belongs to as output.

Consider this code:

var api = AnsiConsole.Prompt(
    new SelectionPrompt<string>()
        .Title("What API do you want to explore?")
        .PageSize(10)
        .MoreChoicesText("[grey](Move up and down to reveal more options)[/]")
        .AddChoiceGroup("Cloud API", new string []
        {
            "Booking API"
        })
        .AddChoiceGroup("Site API", new string[]
        {
            "Booking API"
        }));

If I have the same choice in different groups, I would like to know which group it belongs to.

Right now I would have to wrap the strings in my own little class such as:

public class Choice
{
    public string Name { get; set; }
    public string Group { get; set; }

    public override string ToString() => Name;
}

Describe the solution you’d like A clear and concise description of what you want to happen.

Would be great if somehow SelectionPrompt and MultiSelectionPrompt could somehow also return the choice group when returning a value.

@Cheesebaron I totally get what you’re after, but the problem is that AddChoiceGroup is just a convenience method to add a single level to the tree. It’s also possible to build a selection tree with an arbitrary number of levels.

The result would need to look something like the code below, which I think would make things more complicated than it should be.

public class SelectedChoice<T>
{
    public T Value { get; }
    public bool Selected { get; }
    public Choice<T>? Parent { get; }
}

Perhaps we could add a method to the tree itself to get the parent of a choice?

var group = api.GetParent("Booking API")

Go ahead, have been busy with other things. So please do take a stab at it.
