The next pane is where you actually create attribute, assign
attributes to Attribute Group and Set. The column on the right contains
all unassigned attributes and in the middle you can see attribute groups
(as folders) and assigned attributes (as items in those folders).

Attribute Groups
As we mentioned above, in the middle pane you can see attribute
groups (as folders) and assigned attributes (as items in those folders).
You can drug them and drop into the Unassigned Attributes pane to
unassign them.
When you select different Attribute Sets, you will see a list of
groups assigned to this Set. Please note that the same Group can be
assigned only to one Attribute Set as well as attribute can be assigned
only to one Group in a specific Set. Also you can move the same
attribute between Groups withing one Set only.
You can see Attribute Sets/Groups pane under the Attribute Groups
pane. All Sets/Groups assigned to highlighted attribute (in the
Attribute Groups pane). Also you can move selected attribute between
Groups withing one Set and remove it from Group checking or unchecking
appropriate check-boxes.
You can check or uncheck Group or Set in order remove or add
attribute from/to the list. Note that you cannot remove system
attributes from any list.
You can perform the following Basic Operations:
- Add new product attribute group
calls blank Edit attribute group form, which is used to create a new
attribute group within this attribute set. Groups determine certain
display options/sort order in the front-end so you should use
informative names like "Hardware". - To edit attribute group you can double click on it or use edit attribute group
button. It calls edit attribute group form for highlighted attribute group.

- You can delete selected attribute group from your store
. Pay attention that you won't be able to undo delete from store operation unless you've made d-base backup. - Also you can expand or collapse groups list manually or use Expand/Collapse button.
There are 3 types of attributes:
User Defined Attributes - you can add, edit, delete them.
Visible System Attributes - You can move them between groups but you cannot add, modify or delete them.
Invisible System Attributes - Those are system attributes used by your
Shopping Cart - for internal use only. You cannot add, modify or delete
them.

selected attribute set. Select unassigned attribute from the list and
