Create a Category Page

Create a view for your category called _Category.cshtml and use it in the layout controls in Sitecore. You need a view for relationships displayed on the category page called _CategorySummary.cshtml.

Category.cshtml

@model CategoryViewModel
@{
    ViewBag.Title = Model.DisplayName;    
}
 
<div class="row">
<h1>@Model.DisplayNameRender</h1>
    <p>@Model.DescriptionRender</p>
</div>
<div>
    <ul class="thumbnails">
        @foreach (var product in Model.ChildProducts)
        {   
            <li class="span3">
                @Html.Partial("~/Views/Catalog/_ProductSummary.cshtml", new ProductViewModel(product))
            </li>  
        }
    </ul>
</div>

ProductSummary.cshtml

@model ProductViewModel
@{
    var mod = (ProductViewModel)Model;
}
 
<a href="@Sitecore.Links.LinkManager.GetDynamicUrl(mod.Item)">
    <div class="thumbnail">
        <img src="@mod.FirstImagePath(ImageSize.Detail)" alt="">
        <div class="productLabel">
            <span class="label label-success">@mod.ListPriceRender</span><span class="label label-productName">@mod.DisplayNameRender</span>
        </div>
        <div class="detailsFloatOver">
                <h4>@mod.DisplayNameRender </h4>
                <p>@mod.ListPriceRender</p>
        </div>
    </div>
</a>

Create your basic view model for categories.

    public class CategoryViewModel : Sitecore.Mvc.Presentation.RenderingModel, IImageEntity
    {
        private Item _item;
 
        public CategoryViewModel() { }
        public CategoryViewModel(Item item) { this._item = item; }
 
        public override Item Item
        {
            get
            {
                if (this._item == null)
                    return base.Item;
 
                return this._item;
            }
        }
 
        public string DisplayName { get { return this.Item.DisplayName; } }
        public HtmlString DisplayNameRender
        {
            get
            {
                return PageContext.Current.HtmlHelper.Sitecore().Field(Sitecore.FieldIDs.DisplayName.ToString(), this.Item);
            }
        }
 
        public string Description
        {
            get { return this.Item["Description"]; }
            set { this.Item["Description"] = value; }
        }
 
        public HtmlString DescriptionRender
        {
            get
            {
                return PageContext.Current.HtmlHelper.Sitecore().Field("Description", this.Item);
            }
        }
 
        public string ImageFilename
        {
            get { return this.Item["Image_filename"]; }
            set { this.Item["Image_filename"] = value; }
        }
 
        public List<Item> ChildProducts { get; protected set; }
        public List<Item> ChildCategories { get; protected set; }
 
        [System.Xml.Serialization.XmlIgnore]
        protected ViewContext CurrentViewContext { get { return ContextService.Get().GetCurrentOrDefault<ViewContext>(); } }
 
        public void Initialize(Rendering rendering, List<Item> products, List<Item> childCategories)
        {
            base.Initialize(rendering);
 
            if (products != null && products.Count > 0)
                this.ChildProducts = products;
 
            if (childCategories != null && childCategories.Count > 0)
            {
                this.ChildCategories = childCategories;
            }
        }
    }

Create an action controller.

public ActionResult Category()
        {
            var viewModel = GetCategoryViewModel(this.Item, this.CurrentRendering);
            return View(this.CurrentRenderingView, viewModel);
        }

        protected virtual CategoryViewModel GetCategoryViewModel(Item categoryItem, Rendering rendering)
        {
            if (HttpContext.Items[_CurentCategoryViewModelKeyName] == null)
            {
                var categoryViewModel = new CategoryViewModel();
                var childProducts = categoryItem.Children.ToList();
                categoryViewModel.Initialize(rendering, childProducts, new List<Item>());
                HttpContext.Items[_CurentCategoryViewModelKeyName] = categoryViewModel;
            }
 
            var viewModel = (CategoryViewModel)HttpContext.Items[_CurentCategoryViewModelKeyName];
            return viewModel;
        }
