Blazor 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.

The Menu component is part of Telerik UI for Blazor, a professional grade UI library with 100+ native components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.

Creating Blazor Menu

1. Use the TelerikMenu tag to add the component to your razor page.

2. Populate the Data property with the collection of items that you want to appear in the menu. The Menu will automatically recognize property names like Id, ParentId, Text and a few others. Otherwise, use bindings to configure custom property names.

<TelerikMenu Data="@MenuItems"/>

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

    public class MenuItem
    {
        public string Text { get; set; }
        public string Url { get; set; }
        public List<MenuItem> Items { get; set; }
    }

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

        base.OnInitialized();
    }

Data Binding

To show any items, the Blazor Menu requires a data source that you can provide through the Data property. The Menu allows you to display the items both as flat data and hierarchically. Read more about the Blazor Menu data binding...

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 that the menu will generate if you provide a URL for the given item. This approach is demonstrated in the Creating Blazor Menu example.
• Use a Template to generate the desired links (e.g., NavLink components) with your own code to enable fine-tuning.

Orientation

The Blazor Menu allows you to control its orientation and display the items horizontally or vertically. Read more about the Blazor Menu orientation...

Show and Hide Behavior

By default, the Menu child items are displayed on mouse hover over the parent item and hidden on mouse leave. You can configure the Menu to show and hide child items by clicking or tapping the parent.

Templates

You can use the functionality of the built-in templates and customize what is rendered in the items. Read more about the Blazor Menu templates...

Menu Icons

To illustrate the purpose of each menu item, the Blazor Menu allows you to add images, icon classes, or font icons. Read more about the Blazor Menu icons...

Events

The Blazor Menu generates events that you can handle and further customize its behavior. Read more about the Blazor Menu events...
