The customer's problem
Turbo Powersports sells parts and accessories for ATV, snowmobile, and jet ski — a very wide catalog with many category levels. The theme they were using had only a simple header menu and a hamburger slide menu on mobile.
Two clear problems:
1. No mega menu — the whole catalog was hidden behind a short dropdown in the header. Visitors landing on the store couldn't tell what was being sold, there were no representative images, and no easy way to glance through the main product groups.
2. Slide menu was basic, not properly tiered — the theme's default slide menu was there, but it only listed top-level items, without enough sub-levels for a catalog this deep.
