1) Open up the Items dropdown on the left of your screen and click on the Modifiers page; this will bring you to the Modifiers screen. Click on the "+ Add Modifier" button on the right side of your screen.
2) This will open up a dialog for adding a modifier. Fill in your modifier to your liking and assign it to either items or categories. Depending on which items and categories you have added prior will show in the dropdown.
You can add multiple Items or Categories to each modifier just by clicking on the dropdown after assigning it to either Items or Categories and either clicking and choosing or searching for your desired choice.
After filling out the modifier details, click the "Save Changes" button.
3) Now, you should add an Item to the modifier. On the same modifiers screen, scroll down until you see the "Modifier Items" table. Click on either of the "Add" buttons.
4) This will open up a dialog for adding a modifier Item, such as extra sides, etc. You can add the name of the modifier item and the price. After adding the information needed, click "Create".
5) After creating, you should see your modifier item in the modifiers table. Now, go to the item/category of the modifier you added, scroll down inside the item, and you should see the "Modifiers" table with your new modifier inside there. The screenshot below shows inside the "New Category" created previously in the Create Category section. Because this specific modifier was added to the whole category, all items in that category will hold this same modifier.
Edit a Modifier
1) To edit a modifier, first, find the Modifiers page again to see all of your added modifiers.
2) Click on the vertical ellipsis on the right-hand side of the row you want to edit. This will show a dropdown for either edit or delete. You can also click on the modifier name itself of the row you want to edit, and it will take you straight to the edit page.
(Note: When clicking delete on a modifier, it shows a dialog, once confirming to delete, you cannot get this modifier back and will have to add everything manually again.)
3) Clicking edit will open a new page for the modifier. In here, you can add or edit any of the items added or the fields for the modifier itself.
