An editor extension collection is a group of related extensions in the same app. If your app has two or more extensions that are designed to work together, group them in a collection to let merchants know that they should add the entire collection. The following is an example of how an editor extension collection shows up in the **Apps** tab of the checkout and accounts editor: ![The editor extension collection in the checkout and accounts editor](/assets/apps/customer-accounts/editor-extension-collections/extension-collection-overview.png) ## How it works Apps in customer accounts often include multiple extensions that need to work together to provide a complete experience. Instead of expecting merchants to figure out which extensions these are, you can create an editor extension collection. Merchants need to add each extension from a collection one by one. They cannot add the entire collection all at once. This ensures that merchants can preview each extension and configure extension settings before adding the next one. To create an editor extension collection, you'll need to generate a new config-only extension in the [shopify.extension.toml](/docs/apps/build/app-extensions/configure-app-extensions#editor-extension-collection) file within your app. This file is used to specify the details of each editor extension collection. ## Limitation Currently, collections can only contain customer account UI and checkout UI extensions. ## Next steps
