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. # Method Code Examples: *** Note: do not assume any prop names or enum values other than the ones in the example. ## bulkUpdateModifierGroups example for dashboard page code ```javascript import { itemModifierGroups } from 'wix-restaurants.v2'; async function bulkUpdateModifierGroups(modifierGroups, options) { try { const result = await itemModifierGroups.bulkUpdateModifierGroups(modifierGroups, options); return result; } catch (error) { console.error(error); // Handle the error } } ``` ## bulkUpdateModifierGroups example for exporting from backend code ```javascript import { itemModifierGroups } from 'wix-restaurants.v2'; import { webMethod, Permissions } from 'wix-web-module'; import { elevate } from 'wix-auth'; const elevatedBulkUpdateModifierGroups = elevate(itemModifierGroups.bulkUpdateModifierGroups); export const bulkUpdateModifierGroups = webMethod( Permissions.Anyone, async (modifierGroups, options) => { try { const result = await elevatedBulkUpdateModifierGroups(modifierGroups, options); return result; } catch (error) { console.error(error); // Handle the error } } ); ``` ---
