呈现复杂类型的文本框？

Question

I have been reading the various blog posts on how to deal with a Complex Type in EF including the brad wilson post which most everyone seems to link. owever i dont really get it. I am using EF code first development, MVC and VB. From what i have read so far to render a editor field for a complex types requires a custom object, right? However i dont really understand what code i need to put into the custom template. Can someone break it down for me as to what code needs to go into custom templete so i can render a textbox for the PostTags icollection?

My classes:

 Public Class Post
    Inherits EntityBase

    <Key()> Property PostId As Integer
    <DisplayName("Title")> <Required()> Property PostTitle As String
    <UIHint("MultilineText")> <DisplayName("Text")> Property PostText As String

    ReadOnly Property PostExcerpt As String
        Get
            If PostText.Length > 100 Then
                Return Helpers.TruncateHelper.TruncateAtWord(PostText, 250)
            Else : Return PostText
            End If
        End Get
    End Property

    <ScaffoldColumn(False)> Property PostDateCreated As DateTime
    <ScaffoldColumn(False)> Property PostDateModified As DateTime?
    <ScaffoldColumn(False)> Property PostDatePublished As DateTime?

    <DisplayName("Publish?")> Property PostIsPublished As Boolean
    <DisplayName("Allow Comments?")> Property CommentsAllowed As Boolean
    <ScaffoldColumn(False)> Property CategoryId As Integer?
    <UIHint("Text")> <DisplayName("Category")> <Required()> Property PostCategory As String
    Property Comments As IList(Of Comment)

    'Post has collection of Tags
    <DisplayName("Tags (comma separated)")> Overridable Property PostTags As ICollection(Of Tag)
End Class


    Public Class Tag
    Dim _rdsqlconn As RDSQLConn

    <Key()> Property TagId As Int32
    Property PostId As Int32
    Property TagWord As String

    'Overridable property to access Post
    Overridable Property Post As Post

End Class

Solved.

Created the template Tags.vbhtml in the EditorTemplates folder and applied to PostTags. the template has the textbox which is shown in the view.
