Hi Hubert,

This is a partial view I use for a doctype grid editor I use in one of the older projects.

There is some stuff you don't need for instance a title and all the markup but it should at least get you started. If you have any questions please do ask.

@if (Model != null && Model.MediaFolder != null)
{
    if (Model.Title != null)
    {
        <h2>@Model.Title</h2>
    }
    if (Model.MediaFolder.DocumentTypeAlias != "Folder")
    {
        <a href="@Model.MediaFolder.Url">@Model.MediaFolder.Name</a>
    }
    else
    {
        <ul class="DownloadTree tree">
            @foreach (IPublishedContent node in Model.MediaFolder.Children)
            {
                if (node.DocumentTypeAlias == "Folder")
                {
                    @RenderFolder(node, false)
                }
                else
                {
                    @RenderFile(node, false)
                }
            }
        </ul>
    }
}


@helper RenderChildren(IEnumerable<IPublishedContent> nodes)
    {
        <ul>
            @foreach (var node in nodes)
            {
                if (node.DocumentTypeAlias == "Folder")
                {
                    @RenderFolder(node, true)
                }
                else
                {
                    @RenderFile(node, true)
                }
            }
        </ul>
}

@helper RenderFolder(IPublishedContent node, bool hide)
    {
        int childrenCount = node.Children.Count();
        <li class="treeFolder @(childrenCount != 0 ? "branch":"")" style="@(hide ? "display: none;": "display: list-item;")">
            <i class="indicator fa fa-folder"></i>
            <a href="#" class="@(childrenCount == 0 ? "empty":"")">@node.Name (@childrenCount)</a>
            @if (childrenCount > 0)
            {
                @RenderChildren(node.Children)
            }
        </li>
}

@helper RenderFile(IPublishedContent node, bool hide)
    {
        <li class="treeDownload" style="@(hide ? "display: none;": "display: list-item;")">
            @{
                <a href="@node.Url" target="_blank" download>@node.Name</a>
            }
        </li>
}
