how can i make a menu?

The menu for the MVC application is defined in the file "Views" folder->"Shared" folder ->_Layout.cshtml file

If you open the file and browse it through you will see entries like

<nav>
    <ul id="menu">
        <li>@Html.ActionLink("Home", "Index", "Home")</li>
        <li>@Html.ActionLink("About", "About", "Home")</li>
        <li>@Html.ActionLink("Contact", "Contact", "Home")</li>
    </ul>
</nav>

This is where you will defined your new menu and please google it, if you needs to know the parameter for

@Html.ActionLink

Hope this helps

create an entity class with menu and sub menu relalted logic, that work as model.

public int Id { get; set; }
public string Name { get; set; }
public string Action { get; set; }
public string Controller { get; set; }
public List<Menu> SubMenu { get; set; }

In controller you have to add one method in your base class.This base class should be exectued by each and every pages of your application.

public ActionResult MenuBar()
        {
            var menuItems = from t in dbContext.GetMenuItem(Session["LoggedInID"])
                            select t;

            return PartialView("Menubar", menuItems);

        }

create one basePage that inherited by every controller.

and then finally create one view that need to put in Layout.cshtml page.

@Html.Action("Menubar");

and In View you have to put loop for your model and will create relavant html to load your menu based on your desing.
