MVC Code-First migration scaffold self-referential model

I have a constructed a model using code first in C#. The model literally represents a container element for a website building application, in other words, the model defines a Div tag or some such HTML element. Like a Div tag which can contain multiple child elements, I have tried to represent this in my model, but the scaffolding to the DB, does not give me what I'd expect.

I should get a new many to many joins table, but instead I only get a single column in the DB which expects a single int data type.

Here is the model:

public class ElementContainer
    {
        public int ElementContainerID { get; set; }
        public int PageId { get; set; }
        public int? ParentElementContainerID { get; set; }
        public string ElementContainerName { get; set; }
        public ElementType ElementType { get; set; }
        public string ElementClass { get; set; }

        public List<ElementContainer> NestedContainers { get; set; }
    }

Select allOpen in new window

The last line is the self-referential attribute which just appears as a column called ElementContainer_ElementContainerID

Thanks in advance!
