The Blazor Sidebar is an expandable and collapsible component that typically acts as a side container in which to place primary or secondary content alongside the main content. It provides a flexible container that can be expanded or collapsed based on user interactions. Any type of HTML content or component can be placed in the Blazor Sidebar control for quick access and for easy navigation, like quick references, menus, lists, and tree views.

Transitions and animation

Different types of slide-out content in the Blazor Sidebar component give users the flexibility to view or hide content over or above the main content by pushing, sliding, or overlaying it.

HTML side content position

The Blazor Sidebar component positions its content to the left or right side of the main content area. This allows the placement of two sidebars in a page, both at the left and right, to show primary and secondary content simultaneously.

Dock the HTML side panel content

When you dock the side content to give the main content more space, the navigation text is represented as a shortened view of icons.

Toggle sidebar menu

Bind custom actions to any element (hamburger menu or buttons) to toggle a sidebar.

Responsive sidebar

Auto closing the Blazor Sidebar component’s content allows the main content area to be more readable.

Mobile-friendly side navigation menu

The Blazor Sidebar component’s responsive mode gives an adaptive, redesigned UI appearance for mobile devices.

Shows the Blazor sidebar inside the mobile panel.

Developer-friendly APIs

Developers have control over all the UI elements and behaviors of the components to provide the best experience to end users with a rich set of developer-friendly APIs.

Other supported frameworks

Sidebar is also available in JavaScript, Angular, React and Vue frameworks that are built from their own TypeScript libraries. Check out the different Sidebar platforms from the links below,

No, our 1,800+ components and frameworks for web, mobile, and desktop, including our Blazor Sidebar, are not sold individually. They are only available as part of a team license. However, we have competitively priced the product, so it only costs a little bit more than what some other vendors charge for their Sidebar component alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 1,800+ components and frameworks for a subscription fee that starts at $395 per month for a team of 5 developers. Additionally, we might be able to offer discounts based on currently active promotions. Please contact our product specialists today to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue, 5 or fewer developers, and 10 or fewer total employees.

A good place to start would be our comprehensive getting started documentation.
