Try something like this:

<ul class="nav clearfix">
@foreach (var level in @Model.AncestorsOrSelf(2).Where("Visible"))
{
    if (@level.Level == 2)
    {
        foreach (var item in @level.Children.Where("Visible").Where("NodeTypeAlias == \"Folder\"))
        {
        <li><a class="@{if(@Model.Url == @item.Url){@Html.Raw("selected");}}" href="@item.Url">@item.Name</a></li>
        }
    }
} 
</ul>

Or you might be able to do something like this:

foreach (var item in @level.Folder.Where("Visible")) {...}

Of course you'd have to replace Folder with the actual document type.

Dummy 5 is actually not a folder, it's a 'page' of content of a particular data type. 

Yeah, you'd have to substitude "Folder" with the actual document type alias.

As in this?

The problem here is that I have many types... Seems cumbersome to list every individual type that should or should not appear on the nav. 

If you in fact need only the first child item you can select it with:

@Model.Children.First()

I don't think he's looking for the first item. He's looking to filter the results. I  know of no other "magic" way to filter those results than by adding a property to the Document Type or using the NodeTypeAlias.

Hmm. Well that won't work either:

Dummy and Another Page need to show, but nothing else should.

My Sub Nav is in the master page, so I guess the only way around this is to add:

.Where("NodeTypeAlias" != "Gallery Item").Where("NodeTypeAlias" != "Promotion Item")

etc

Is that the only way to do it? No internal way of determining a data type is a stranged piece of content, or an actual page?

"I don't think he's looking for the first item. He's looking to filter the results. I  know of no other "magic" way to filter those results than by adding a property to the Document Type or using the NodeTypeAlias."

Yup. That's what I thought.

@foreach (var level in @Model.AncestorsOrSelf(2).Where("Visible"))

{

    if (@level.Level == 2)

    {

        foreach (var item in @level.Children.Where("Visible").Where("NodeTypeAlias" != "GalleryMediaItem"))

        {

        <li><aclass="@{if(@Model.Url == @item.Url){@Html.Raw("selected");}}"href="@item.Url">@item.Name</a></li>

        }

    }

} 

Doesn't seem to work...

I've thought that you could just declare some property for the document types you need to show without asigning it any value and filter you content with HasProperty() method.

.Where("NodeTypeAlias" != "GalleryMediaItem"))

Will do the job if I knew the syntax!

Got it thanks!

You can also use the parameterized syntax:

blablabla.Where("NodeTypeAlias != @0", "GalleryMediaItem")

 (Personally I prefer it so that not to mess about with backslashes)

Sweet cheers.

That's pretty neat. I didn't know about the parameterized syntax.

is working on a reply...
