The Challenge

What we needed to solve.

  • Managing thousands of colorways, sizes, and fabric weights caused severe navigation overload for shoppers.
  • B2B wholesale buyers needed fast matrix-style bulk ordering without visiting individual product pages.
  • Collection pages with hundreds of items suffered from slow DOM rendering.
The Approach

How it was built.

01

Dynamic Multi-Column Mega Nav

Built an ultra-fast mega navigation drawer with image previews, popular search tags, and instant sub-category links.

02

Quick-Order Bulk Matrix

Engineered a wholesale variant table allowing buyers to select quantities across all sizes/colors in one grid and add to cart simultaneously.

03

Virtual Scroll Collection Grid

Implemented lazy DOM rendering for collection pages to keep scrolling buttery smooth regardless of SKU counts.
