A mega menu panel with 25 subcategory links arranged randomly is hard to scan. The same 25 links organized into five labeled groups of five items each becomes instantly navigable. Grouping transforms a wall of text into a structured overview.
Grouping by product type
The most common approach: group subcategories by what the product is. Under “Women,” the groups might be “Clothing,” “Shoes,” “Bags,” “Jewelry,” and “Beauty.” Each group contains the specific product types within it.
This works for most ecommerce stores because it matches how shoppers think about products. A shopper looking for shoes scans the headings, finds “Shoes,” and drills into that column. They don’t need to read the other columns.
Grouping by audience
For stores selling to distinct audiences, grouping by who the product is for makes sense. A family clothing store might group by “Women,” “Men,” “Kids,” and “Baby” within a broader “Clothing” mega menu.
Audience grouping works when the products are similar across audiences but the shopper identifies with one group. A parent shopping for kids’ shoes doesn’t want to scan past adult shoes to find the children’s section.
Grouping by use case
Intent-based grouping organizes products by why the shopper is buying. Under “Shoes,” the groups might be “Running,” “Casual,” “Formal,” “Hiking,” and “Beach.” Each group crosses traditional product type boundaries (sneakers, sandals, boots) and focuses on the occasion.
This is effective for stores where the use case is the primary decision factor. A shopper buying running shoes doesn’t think “I need athletic footwear in the sneaker subcategory.” They think “I need shoes for running.”
Group sizing and balance
Each group should contain 4–8 items. Fewer than 4 makes the group feel sparse. More than 8 makes it too long to scan quickly.
Groups should be roughly balanced in size. A panel with one group of 15 items and three groups of 3 items looks lopsided. If one category has significantly more subcategories than others, split it into two groups or move the less important items to a “View all” link.
The “View all” link at the bottom of each group (or at the bottom of the panel) catches everything that doesn’t fit in the curated list. “View all Women’s Shoes (89)” gives the shopper a path to the complete collection while keeping the mega menu panel focused.
Heading clarity
Group headings should be clear and distinct from the subcategory links below them. Visually: bold, slightly larger font, maybe a different color. Semantically: the heading should describe the group, not just be the first item in the list.
“Clothing” as a heading with “Tops, Bottoms, Dresses” below it is clear. “Tops” as a heading with “T-shirts, Blouses, Sweaters” below it is also clear. “Shop” as a heading with random product links below it is not helpful.
