[c#] Foreach in a Foreach in MVC View

Controller

public ActionResult Index()
    {


        //you don't need to include the category bc it does it by itself
        //var model = db.Product.Include(c => c.Category).ToList()

        ViewBag.Categories = db.Category.OrderBy(c => c.Name).ToList();
        var model = db.Product.ToList()
        return View(model);
    }


View

you need to filter the model with the given category

like :=> Model.where(p=>p.CategoryID == category.CategoryID)

try this...

@foreach (var category in ViewBag.Categories)
{
    <h3><u>@category.Name</u></h3>

    <div>

        @foreach (var product in Model.where(p=>p.CategoryID == category.CategoryID))
        {

                <table cellpadding="5" cellspacing"5" style="border:1px solid black; width:100%;background-color:White;">
                    <thead>
                        <tr>
                            <th style="background-color:black; color:white;">
                                @product.Title  
                                @if (System.Web.Security.UrlAuthorizationModule.CheckUrlAccessForPrincipal("/admin", User, "GET"))
                                {
                                    @Html.Raw(" - ")  
                                    @Html.ActionLink("Edit", "Edit", new { id = product.ID }, new { style = "background-color:black; color:white !important;" })
                                }
                            </th>
                        </tr>
                    </thead>

                    <tbody>
                        <tr>
                            <td style="background-color:White;">
                                @product.Description
                            </td>
                        </tr>
                    </tbody>      
                </table>
