Activate the option"Allow editing the catalogue"in the warehouse settings] in order to enable the displaying of product groups.
Product groups are managed on the "Product Groups" page, which is located in the "Warehouse" section of the "Activities" area in the system. The lines can be moved and the order of the groups in the catalogue can be changed.
The folder icon indicates that there are subgroups within a product group. The number next to the folder shows the number of subgroups. If you click on the folder or the number, a list of subgroups will open. You can return to the root of the catalogue using the line/string where the catalogue path is written.
To edit a group or subgroup, simply click on its name.
