I'm quite new to EPiServer so maybe there is a really easy solution to my problem, but I can't find any good information about this.

In a current project there is a demand that the editor should be able to add document lists on pages. These document lists should be able to list files and subfolders in the selected folder.

I was thinking that I could create a nested ul-list and expand/minimize the folders when the user clicks them.

My problem is how do I loop through content folders and their subfolders and create links to the files that are inside?

Can I use a ContentReference property to get a reference to the top-level folder and then loop through all the childnodes?

Should I create a custom object (like below) and render that in the Block View or is there a better way?

public class Folder {
    public string Name{get; set;}
    public IENumerable Files {get; set;}
    public IENumerable ChildFolders {get; set;}
}
