I'm building a Section Menu which is nearly there. However when I get to the bottom level or a level where there are no children i want to display all the immediate parents items. So far I have

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage


@* Ensure that the Current Page has children, where the property umbracoNaviHide is not True *@
@if (CurrentPage.Children.Where("Visible").Any())
{
@* Get the first page in the children, where the property umbracoNaviHide is not True *@
var naviLevel = CurrentPage.Children.Where("Visible").First().Level;

@* Add in level for a CSS hook *@
<ul class="portfolio-categ filter">      
    @* For each child page under the root node, where the property umbracoNaviHide is not True *@
    @foreach (var childPage in CurrentPage.AncestorOrSelf(2).Children.Where("Visible"))
    {
        <li>
            <a href="@childPage.Url">@childPage.Name</a>

            @* if the current page has any children, where the property umbracoNaviHide is not True *@
            @if (childPage.Children.Where("Visible").Any())
            {                    
                @* Call our helper to display the children *@
                @childPages(childPage.Children)
            }
        </li>
    }
  </ul>
  }


  @helper childPages(dynamic pages)
    {
   @* Ensure that we have a collection of pages *@
  if (pages.Any())
{
    @* Get the first page in pages and get the level *@
    var naviLevel = pages.First().Level;

    @* Add in level for a CSS hook *@
    <span class="level-@(naviLevel)">
        @foreach (var page in pages.Where("Visible"))
        {
            <li>
                <a href="@page.Url">@page.Name</a>

                @* if the current page has any children, where the property umbracoNaviHide is not True *@
                @if (page.Children.Where("Visible").Any())
                {                        
                    @* Call our helper to display the children *@
                    @childPages(page.Children)
                }
            </li>
        }

    </span>
}else{<span> <p>hello</p> </span>}
}
