Rule action: Build item group

• Create a list of values, such as brands or colors, from your items based on a group ID.

Use the Build item group action to create lists based on a grouping identifier, such as item_group_id. For example, you can create a list using values from specific fields.

Let's say we have data for items of different brands and colors, and we want to create lists for all the brands and colors.

id	item_group_id	brand	color	brand_list	color_list
1	1	Nike	White
2	1	Adidas	Purple
3	1	Puma	Yellow
4	2	New Balance	Beige
5	2	Vans	Black
6	3	Crocs	Green

If you use the Build item group action and use the brand and color fields, the result will be a complete list of brands and a list of colors.

id	item_group_id	brand	color	brand_list	color_list
1	1	Nike	White	Nike, Adidas, Puma	White, Purple, Yellow
2	1	Adidas	Purple	Nike, Adidas, Puma	White, Purple, Yellow
3	1	Puma	Yellow	Nike, Adidas, Puma	White, Purple, Yellow
4	2	New Balance	Beige	New Balance, Vans	Beige, Black
5	2	Vans	Black	New Balance, Vans	Beige, Black
6	3	Crocs	Green	Crocs	Green
