Garmin device retail Shopify Wide catalog

At a glance

Industry: Garmin device retail (GPS, smartwatch, marine…)

Challenge: A wide catalog — no single menu can handle it all
Navi+ menus: Desktop Mega Menu · Slide Menu · Tab Bar (a coordinated trio)
Focus: A complete solution: desktop + mobile + tab bar

The customer's problem

GPS Nation sells almost the entire Garmin ecosystem: smartwatches and wearables, handheld outdoor devices, marine (sonar, chartplotter, radar), road GPS, cycling computers, hunting dog tracking, all the way to refurbished gear — a wide, multi-level catalog organized by how it's used.

With a catalog like this, no single type of menu can handle it all: desktop needs to cover a lot so customers can see everything the store carries; mobile needs to go deep and stay tidy through many levels; and actions like search and cart must always be within reach. Use just one menu and you always fall short on some front — a mega menu is useless on mobile, the default hamburger can't showcase the catalog, and an action bar can't hold an entire category tree.

What Navi+ solves

This is where Navi+'s power trio shines brightest: it's not about choosing one menu, but using all three as one complete solution — each handling a context, working together to cover everything from discovery to purchase, on every device.

Desktop Mega Menu — covering the whole catalog by use case

On desktop, the Mega Menu is split into columns by use case: Smartwatch & Wearables, Outdoor, Marine, Road, Sport & Fitness, Refurbished — each column with familiar sub-groups (running, cycling, golf, fishfinder…) alongside imagery. A quick hover and customers see exactly the branch they care about, without needing to know the product line name in advance.

Slide Menu — going deep: use case → line → model

The Slide Menu handles the deep part of the catalog: customers go from a need group (Sport & Fitness) into a specific sport (Running) and then to each product line, screen by screen like a native app. On mobile this is the main navigation axis; on desktop it's the option for customers who prefer browsing as a list.

Tab Bar — putting Search and Cart within thumb's reach on mobile

For a store with many SKUs, search is the most important shortcut. The Tab Bar is fixed at the bottom of the mobile screen with Home, Shop/Menu, Search, Cart, Account — and opens the Search panel or Cart panel right where the customer is. Customers comparing many models don't have to scroll back up to the header every time.

The key point: these three menus don't work in isolation. They split roles by device context and share a single catalog structure — forming one complete navigation solution, not three patched-on features.

The intended outcome

Instead of patching each part separately, GPS Nation gets one complete navigation solution: every device has the right tool, and the trio works together to cover everything from the moment a customer explores to the moment they add to cart. That's the power of using all three Navi+ menus as one system, not as separate pieces.

Desktop covers the catalog broadly with the Mega Menu — customers see the entire Garmin ecosystem at once.
Mobile goes deep and tidy through the Slide Menu, sharing the same structure as desktop.
Search and cart are always within thumb's reach thanks to the Tab Bar.
One complete solution, consistent across every device — no theme swap needed.

Key principles

Points that apply to most stores with a wide catalog — not just GPS Nation.

A wide catalog needs a system, not a single menu: no single type of menu handles every context.
Each menu does its own job: desktop covers a lot, mobile goes deep, the tab bar handles actions.
Coordination creates more value than the sum of the parts: only when all three menus share one structure does navigation become seamless.
Add a layer, don't replace the foundation: deploy the whole trio without changing themes or dropping any app you're running.
