Assigning a modifier group to an item is a straight forward step, but when an integration with a POS system is involved, the process becomes a little bit different. Below are the steps that you need to follow to accomplish your task:
Make sure the modifier group is created and assigned to the item in the POS System
Go to FineDine Dashboard,>Market Place>My Integrations>(Your POS) Configuration page, and select "Sync Settings" Tab
Select the modifiers only the be the ones to be synced (This will import any new modifier groups you created in the POS to FineDine
Go to the Sync Menu Tab and select "Sync by item"
Find the item you want and click the update button
