multiple models in mvc view, no EditFor field showing

I have an issue, I am creating a blog based website and one of the things I wanted was to allow Tags on Posts. The relationship in my database and model is a many to many relationship between Post and Tags. However I am struggling to use tags in my Posts create view, the other issue I have is with Entity Framework and my SQL, because it is a many to many relationship no foreign key was assigned in either table. Just the association, when creating a post with a tag will my PostController handle it correctly?

@model MyBlogger.Post

@{
    ViewBag.Title = "Create";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Create</h2>

@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>Post</legend>

        <div class="editor-label">
            @Html.HiddenFor(model => model.BlogUserEmail, User.Identity.Name)
        </div>
        <div class="editor-field">
            @Html.ValidationMessageFor(model => model.BlogUserEmail)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.CategoryId, "Category")
        </div>
        <div class="editor-field">
            @Html.DropDownList("CategoryId", String.Empty)
            @Html.ValidationMessageFor(model => model.CategoryId)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Tags)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Tags) // does not show on the webpage
            @Html.ValidationMessageFor(model => model.Tags)
        </div>

When I run the application no EditorFor field appears. Just the Label for it. I read that you have to decorate something with UIHint however I tried that and it did nothing.

PostController:

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create(Post post, Tag tag)
    {

        int maxLength = 50;
        var Title = post.Title;
        string str = Title.ToLower();
        // invalid chars, make into spaces
        str = Regex.Replace(str, @"[^a-z0-9\s-]", "");
        // convert multiple spaces/hyphens into one space       
        str = Regex.Replace(str, @"[\s-]+", " ").Trim();
        // cut and trim it
        str = str.Substring(0, str.Length <= maxLength ? str.Length : maxLength).Trim();
        // hyphens
        str = Regex.Replace(str, @"\s", "-");

        var TitleTag = tag.Name;
        string tagstr = Title.ToLower();
        // invalid chars, make into spaces
        tagstr = Regex.Replace(str, @"[^a-z0-9\s-]", "");
        // convert multiple spaces/hyphens into one space       
        tagstr = Regex.Replace(str, @"[\s-]+", " ").Trim();
        // cut and trim it
        tagstr = str.Substring(0, str.Length <= maxLength ? str.Length : maxLength).Trim();
        // hyphens
        tagstr = Regex.Replace(str, @"\s", "-");

        post.UrlSlug = str;
        post.BlogUserEmail = User.Identity.Name;
        post.PostedOn = DateTime.Now;

        tag.UrlSlug = tagstr;
        tag.Description = tag.Name;
        try
        {
            if (ModelState.IsValid)
            {
                db.Tags.Add(tag);
                db.Posts.Add(post);
                //how do I make the association between the post and tag?
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            ViewBag.CategoryId = new SelectList(db.Categories, "Id", "Name", post.CategoryId);
            return View(post);
        }
        catch (DbEntityValidationException e)
        {
            var newException = new FormattedDbEntityValidationException(e);
            throw newException;
        }

    }
