Here's how to create a product modifier:
- Sign in to your administrator user account on the web,
- in the sidebar, go to Products -> Modifiers,
- click +ADD to add New modifier set,
- under the 'Name' label, type in the title of a modifier (i.e. temperature),
- in the drop-down menu, specify the modifier type:
- Single (only one option can be selected)
- Multiple (more options can be selected)
- Add modifier options (i.e. hot, cold),
- add modifier prices optionally (you can either set a price or leave this field blank for zero price),
- click SAVE.
After the modifiers have been created, assign them to a product.
