How to add meta-box

Meta Box = Description?

Navigate to Jigoshop > Products > Attributes and then click on an Attribute Label name to go to the configuration page. On this page, you can add new variables to the attribute with a description. If you’ve already created the variable you can click on its Name and edit the variable on the next page.

Note: The proper way to set up variations is via Jigoshop > Products > Attributes.

The description should appear in tabs on product page. If not, you will need theme modification.
