Attributes General Data tab
If at any point you wish to change an attribute that you created incorrectly. You may quickly enable the edit functionality by clicking on the attribute itself.
When you click on an attribute, a tab with editable fields for Name, Type, Default/Values, Description, and Status opens. Every field on the list is editable based on your preferences.
The default/values section should only be used when a certain attribute is required repeatedly. For instance, you always want the currency to be set with default value of 25 Euro.
