Generally speaking it means an accumulation of objects gathered for study, comparison, exhibition or as a hobby.

When you talk about a collection on your online store it means a group of products gathered into collections to make it easier for your customers to find them by category.

To make it clearer here are a few examples of collections that you might see on a store page:

  1. Clothing items for men, women, or children
  2. Items for home decor such as lamps, cushions, or rugs
  3. Items that have a certain size or color
  4. Seasonal products like holiday cards and decorations
