MVC Razor view nested foreach's model

Imagine a common scenario, this is a simpler version of what I'm coming across. I actually have a couple of layers of further nesting on mine....

But this is the scenario

Theme contains List<Category>
Category contains List<Product>
Product contains List<Order>

My Controller provides a fully populated Theme, with all the Categories for that theme, the Products within this categories and the their orders.

The orders collection has a property called Quantity (amongst many others) that needs to be editable.

@model ViewModels.MyViewModels.Theme

@Html.LabelFor(Model.Theme.name)
@foreach (var category in Model.Theme)
{
@Html.LabelFor(category.name)
@foreach(var product in theme.Products)
{
@Html.LabelFor(product.name)
@foreach(var order in product.Orders)
{
@Html.TextBoxFor(order.Quantity)
@Html.TextAreaFor(order.Note)
@Html.EditorFor(order.DateRequestedDeliveryFor)
}
}
}

If I use lambda instead then then I only seem to get a reference to the top Model object, "Theme" not those within the foreach loop.


Is what I'm trying to do there even possible or have I overestimated or misunderstood what is possible?

With the above I get an error on the TextboxFor, EditorFor, etc

Thanks.
