To group items together by color (or any other Attribute), you can use multiple gspro-item-list elements on a single page. You can do this by using “item-attribute-#".
Read item-attribute-# documentation here.
Filtering by item attribute corresponds to the attributes that are set in your Goodshuffle Pro inventory.
Note: item-attribute-#-name & item-attribute-#-value are case sensitive
