@*
    This snippet makes a list of links of all visible pages of the site, as nested unordered HTML lists.

    How it works:
    - It uses a custom Razor helper called Traverse() to select and display the markup and links.
*@

@{ var selection = Model.Content.Site(); }

<div class="sitemap">
    @* Render the sitemap by passing the root node to the traverse helper, below *@
    @Traverse(selection)
</div>


@* Helper method to traverse through all descendants *@
@helper Traverse(IPublishedContent node)
{
    @* Update the level to reflect how deep you want the sitemap to go *@
    const int maxLevelForSitemap = 4;

    @* Select visible children *@
    var selection = node.Children.Where(x => x.IsVisible() && x.Level <= maxLevelForSitemap).ToArray();

    @* If any items are returned, render a list *@
    if (selection.Length > 0)
    {
        <ul>
            @foreach (var item in selection)
            {
            <li class="level-@item.Level">
                <a href="@item.Url">@item.Name</a>
                
                @* Run the traverse helper again for any child pages *@
                @if (!item.HideSubPages) {
                    @Traverse(item)
                }

            </li>
            }
        </ul>
    }
}
