# Why are modifiers not showing in the online checkout?

## Problem

You have stock modifiers with the **Is required** setting enabled, but they do not appear in the online checkout.

## Cause

Modifiers can only be used at [POS](/v1/docs/sell-stock-products-at-pos) and [Food & Beverage checkouts](/v1/docs/create-your-food-beverage-f-b-checkout), but are not available in the online checkout.

## Solution

Add variations to stock items and assign them as add-ons to products. [By creating stock variations](/v1/docs/create-your-stock-products), you can add stock items as an easy upsell opportunity after guests add an associated product to their cart. Variations also allow you to more easily track demand and availability in your inventory.

> [!CAUTION]
> Available on all plans (except Lite Legacy)
> 
> Add different varieties for your stock products (all plans except Lite Legacy). For Lite Legacy customers, contact your customer success manager or the [support team](/v1/docs/contact-roller-support) to unlock this feature.
