Open the product, choose Edit, and go to the allergen grid.
- Denmark and Finland: one button adds the allergens that must be declared, with level of containment Free from. Another adds the same allergens with Undeclared.
- Norway: the button adds Free from for the Norwegian list.
- Sweden: these buttons are not shown. Add each row yourself.
If an allergen is in the product, change that row from Free from to Contains. Then choose Save.
The buttons skip an allergen that is already on the grid, so a second click does not add a duplicate row.
Preparation state for nutrition is a different choice. See Preparation Type (Prepared or Unprepared) Can Be Misunderstood!.
