You can create option group hierarchies based on your business requirement. You can also create sub-option groups in the existing option group. The option group for which you are creating a sub-option group is considered a parent option group. 

To create a sub-option group

  1. Go to ADMIN SETUP > Product Administration > Option Groups. The Option Groups page is displayed.
  2. Click the parent option group to create a new option group. The option group details page is displayed.
  3. Click the vertical ellipsis () icon next to the option group name and click New Sub Option Group. 
  4. In the right panel, in the Details tab, enter the option group name. The Label field is filled automatically.
  5. From the Type dropdown, select the option group type. The supported values are Standalone and Shared.
  6. Enter the description of the new sub-option group. 
  7. Click Save. A new sub-option group is tagged to the existing option group as a hierarchy. 

Repeat from step 3 to step 7 to add more sub-option groups. You can create multiple levels of sub-option groups.
