Menu Overview

The Blazor Menu component displays data (flat or hierarchical) in a traditional menu-like structure. In addition to built-in navigation capabilities, you can browse through the items and their children, define templates for the individual nodes, render text and icons/images, and respond to events.

To use a Telerik Menu for Blazor:

1. add the TelerikMenu tag
2. provide a collection of models to its Data property (read more in the Data Binding article)
3. match the fields in the models with the binding schema for the nodes

Basic menu with hierarchical data binding and built-in navigation

Use a menu to navigate between views

<TelerikMenu Data="@MenuItems"
             UrlField="@nameof(MenuItem.Page)"
             ItemsField="@nameof(MenuItem.SubSectionList)"
             TextField="@nameof(MenuItem.Section)">
</TelerikMenu>

@code {
    public List<MenuItem> MenuItems { get; set; }

    public class MenuItem
    {
        public string Section { get; set; }
        public string Page { get; set; }
        public List<MenuItem> SubSectionList { get; set; }
    }

    protected override void OnInitialized()
    {
        MenuItems = new List<MenuItem>()
        {
            new MenuItem()
            {
                Section = "Company", // items that don't have a URL will not render links
                SubSectionList = new List<MenuItem>()
                {
                    new MenuItem()
                    {
                        Section = "Overview",
                        Page = "company/overview"
                    },
                    new MenuItem()
                    {
                        Section = "Events",
                        Page = "company/events"
                    },
                    new MenuItem()
                    {
                        Section = "Careers",
                        Page = "company/careers"
                    }
                }
            },
            new MenuItem()
            {
                Section = "Services",
                SubSectionList = new List<MenuItem>()
                {
                    new MenuItem()
                    {
                        Section = "Consulting",
                        Page = "consultingservices"
                    },
                    new MenuItem()
                    {
                        Section = "Education",
                        Page = "education"
                    }
                }
            }
        };

        base.OnInitialized();
    }
}

The result from the snippet above, after hovering the "Services" item

Component namespace and reference

@using Telerik.Blazor.Components

<TelerikMenu @ref="theMenu" Data="@menuData" TextField="Page" UrlField="Page">
</TelerikMenu>

@code {
    // the menu is a generic component and its type depends on the model it binds to
    Telerik.Blazor.Components.TelerikMenu<MenuItem> theMenu;

    List<MenuItem> menuData = Enumerable.Range(1, 3).Select(x => new MenuItem { Page = $"page{x}" }).ToList();

    public class MenuItem
    {
        public string Page { get; set; }
    }
}

Navigate Views

A menu is often used to list pages, views or sections in an application so the user can navigate through them. To do that with a menu, you have two options:

• Use the built-in UrlField in the bound data to populate the URLs in the anchors the menu will generate for you if an URL is provided for the given item. An example is available in the beginning of this article.
• Use a Template to generate the desired links (e.g., NavLink components) with your own code to enable fine-tuning.

You can find an example of a menu used to navigate between pages in an app in the Navigation article.
