Side navigation is a website layout feature where the main menu or navigation links are positioned along the left or right side of the page. This structure allows users to access various sections of a website while keeping the content visible, making it a popular choice for dashboards, portfolios, and content-heavy sites.

How does side navigation work?

Side navigation, also called a sidebar menu or vertical navigation, works by anchoring the navigation panel along one edge of the page—usually the left. When visitors browse a website, they can use this side menu to easily explore different pages or categories without needing to scroll back to the top, like they would with a horizontal menu. In many responsive designs, side navigation can collapse into a hamburger menu on mobile devices for a cleaner look.

Why use side navigation in web design?

Side navigation improves usability and structure, especially for websites with a lot of content or deep navigation levels. It provides more vertical space for links compared to top navigation and can display hierarchy more clearly. Designers often use it in tandem with a website layout that prioritizes user flow and accessibility.

Types of side navigation

Static sidebar

Always visible on screen, even as users scroll. Common in admin panels and content management systems.

Collapsible sidebar

Can be expanded or collapsed, offering more screen space for content when needed. Ideal for tools or platforms where screen real estate matters.

Off-canvas sidebar

Hidden off-screen and slides into view when triggered by an icon or button. Frequently used in mobile-responsive AI website builder designs.

Best practices for implementing side navigation

• Limit the number of links: Avoid overwhelming users. Keep options grouped and clearly labeled.
• Use visual hierarchy: Indent sub-items and use font or color variation to show nesting.
• Make it responsive: Ensure your side navigation adjusts smoothly for different screen sizes.
• Highlight the active page: Use colors or icons to show which section the user is currently on.
• Test for usability: Make sure your sidebar works well with screen readers and meets accessibility standards.

FAQs about side navigation

What kinds of websites benefit most from side navigation?

Websites with lots of content, such as knowledge bases, dashboards, or e-commerce stores with multiple product categories, benefit the most from a side navigation layout.

Not at all. As long as your links are crawlable and properly structured with semantic HTML, SEO can remain strong. It’s more about how the content is indexed than where the navigation appears.

It depends on your content volume and user needs. Side navigation is ideal for complex sites, while top navigation works well for simpler websites.
