Website Navigation Structure for Large Sites: A Mega Menu Case Study

In the first phase of this project, we worked with Montana Digital Academy to define strategy, audience, and content priorities.

But strategy alone doesn’t create a successful website.

For large, content-heavy websites, the real challenge is turning that strategy into a clear, scalable website navigation structure-one that helps users find what they need quickly while keeping the site manageable long-term.

In this case study, we’ll walk through how we designed a mega menu navigation system to organize more than 80 pages, support multiple audiences, and create a seamless user experience across four distinct programs.

Why Website Navigation Structure Matters For Large Websites

When a website reaches this level of complexity, navigation isn’t just design—it’s site architecture that directly impacts user experience (UX).

Without a clear website navigation structure:

• Users get lost
• Content becomes harder to manage
• Key information is buried
• Engagement drops

For Montana Digital Academy, the goal was clear:

Build a structure that allows users to easily navigate four programs while maintaining a cohesive experience across the entire site.

The Challenge: Organizing 80 Plus Pages Across Multiple Audiences

A mega menu navigation system is an expanded approach often used on large websites to display multiple groups of links at once, rather than stacking them in a simple dropdown.

For a large, content-heavy website like Montana Digital Academy, a standard dropdown would have required too many clicks and made navigation harder to follow.

Using a mega menu allowed us to organize content clearly, surface key pages, and make it easier for users to find what they need quickly.

Wireframing: The Foundation of Website Navigation Structure

Before any design concepts were created, we moved into wireframing.

Wireframes allow us to define:

• Page layout
• Content hierarchy
• Navigation placement
• User flow

Homepage Wireframe

We started by wireframing the homepage to:

• Introduce all four programs clearly
• Guide users to the right section quickly
• Establish consistent navigation patterns

This ensured that every design decision moving forward was grounded in structure—not guesswork.

Mega Menu Wireframe

Because navigation was such a major component, we didn’t treat the menu as an afterthought.

We created a dedicated wireframe for the mega menu structure.

This allowed us to:

• Map out all program areas
• Organize links in a logical hierarchy
• Ensure clarity for users navigating large amounts of content

The result was a navigation system that could scale with the site without overwhelming users.

How We Designed a Scalable Website Navigation Structure

This phase was highly collaborative. We worked closely with the Montana Digital Academy team throughout wireframing, incorporating feedback at every stage to ensure the structure aligned with both user needs and their internal understanding of the programs.

This wasn’t a one-sided process. By combining our expertise in website navigation structure with their deep knowledge of their organization, we created a solution that was both intuitive and accurate.

Collaborating on a Sitemap for Better Website Navigation

One of the most important parts of this project was collaboration.

Montana Digital Academy knows its programs better than anyone.

They provided a detailed sitemap outlining:

• Program structure
• Content organization
• Relationships between pages

We worked closely with their team to refine that sitemap into a functional website navigation structure.

This collaboration ensured:

• Accuracy in content organization
• Alignment with real user needs
• A structure that supports long-term growth

Designing Around Structure (Not the Other Way Around)

Once the wireframes and sitemap were finalized, we moved into design samples.

Instead of designing dozens of pages individually, we focused on creating scalable templates.

Homepage Design

The homepage design brought the wireframe to life by:

• Highlighting all four programs
• Reinforcing navigation pathways
• Creating a clear visual hierarchy

Program Page Designs

Since the site is built around four main programs, we created:

• Four distinct program page designs
• Each with its own identity
• While maintaining overall brand consistency

Every page on the site would fall into one of two categories:

• A program-specific page
• A general content page

This approach enabled a consistent design across all 80+ pages to be applied efficiently.

Improving User Experience With Visual Navigation Cues

To help users always understand where they are within the site, we implemented a simple yet powerful solution.

We selected five stock images of Montana mountain landscapes:

• One for each of the four programs
• One for general site pages

Each image was used as the hero image across its section.

This created:

• Instant visual recognition
• Clear separation between program areas
• A more intuitive browsing experience

Users always know which section they’re in without needing to think about it.

Creating a Scalable Mega Menu for Website Navigation

With wireframes, sitemap, and design in place, we finalized the website navigation structure through a robust mega menu.

Rather than building a static navigation system, we developed the mega menu dynamically within WordPress, allowing the client to easily manage and update it from the backend as their content evolves.

The mega menu includes:

• Individual dropdowns for each program, along with a dedicated “Resources & About” section
• Organized links grouped by relevance

This structure allows users to:

• Quickly find what they need
• Navigate across programs easily
• Access key information with a “no more than two clicks away” approach

At the same time, it gives the Montana Digital Academy team full control to update navigation as programs grow, content changes, or priorities shift—without needing ongoing developer support.

Organizing Content by Program

To keep the site flexible and engaging, each program section in the mega menu includes dynamic areas where the client can feature:

• Blog posts
• Events
• Announcements

This ensures the site stays fresh while keeping content organized within the overall navigation structure.

From Navigation Strategy to Scalable Website Development

Once the navigation structure and designs were finalized, we moved into development.

We:

• Built the site framework
• Applied homepage and program page styles across all pages
• Ensured consistency across 80+ pages
• Maintained alignment with the established structure

Because the foundation was strong, development was efficient, and the final product remained consistent throughout.

Results: A Clear, Scalable Website Structure

The result of this process was a website navigation structure that handled complexity without overwhelming users.

Instead of forcing visitors to dig through layers of content, the new structure makes it easy to navigate across all four programs, find key information quickly, and understand exactly where they are within the site at all times.

By combining a well-defined sitemap, strategic wireframing, and a carefully structured mega menu, we created a system that:

• Simplifies navigation across 80+ pages
• Supports multiple audiences with different needs
• Keeps important content accessible within two clicks
• Allows our client to manage and update content easily

Just as importantly, the structure was built to scale.

As programs grow and new content is added, the navigation system can evolve without becoming disorganized or difficult to manage—ensuring the site remains effective long after launch.
