## Introduction

> **Note:** The Item Modifier Groups API only works with the Wix Restaurants Menus app. Make sure you downloaded this app from [Wix App Market](https://www.wix.com/app-market/wix-restaurants-menus-new).

Updates multiple item modifier groups at once. This function supports partial updates.
Each time a modifier group is updated, its revision increments by 1. The existing revision must be included when updating an item modifier group. This ensures you're working with the latest item information, and prevents unintended overwrites.
Up to 100 modifier groups can be returned per request.

### Examples

### bulkUpdateModifierGroups
```javascript
import { itemModifierGroups } from '@wix/restaurants';

async function bulkUpdateModifierGroups(modifierGroups,options) {
  const response = await itemModifierGroups.bulkUpdateModifierGroups(modifierGroups,options);
};
```

### bulkUpdateModifierGroups (with elevated permissions)
```javascript
import { itemModifierGroups } from '@wix/restaurants';
import { auth } from '@wix/essentials';

async function myBulkUpdateModifierGroupsMethod(modifierGroups,options) {
  const elevatedBulkUpdateModifierGroups = auth.elevate(itemModifierGroups.bulkUpdateModifierGroups);
  const response = await elevatedBulkUpdateModifierGroups(modifierGroups,options);
}
```

### bulkUpdateModifierGroups (self-hosted)
Self-hosted SDK calls require you to [create a client](https://dev.wix.com/docs/sdk/articles/work-with-the-sdk/about-the-wix-client.md).

```javascript
import { createClient } from '@wix/sdk';
import { itemModifierGroups } from '@wix/restaurants';
// Import the auth strategy for the relevant access type
// Import the relevant host module if needed

const myWixClient = createClient ({
  modules: { itemModifierGroups },
  // Include the auth strategy and host as relevant
});


async function bulkUpdateModifierGroups(modifierGroups,options) {
  const response = await myWixClient.itemModifierGroups.bulkUpdateModifierGroups(modifierGroups,options);
};
```
