Can I use 1 attribute value list for multiple attributes?
There is currently no option (yet) to share 1 list of attribute values among multiple attributes.
Attributes (for products, shipping units, projects, etc.) can be setup as single or multi select. This means that the user can select 1 (single select) or multiple (multi select) values. The list of attribute values is unique for each attribute. So there is currently no option (yet) to share 1 list of attribute values among multiple attributes.
