CMS: Accessing and Syncing Your Sandbox and Live Collections
If you've enabled the sandbox in your CMS (Content Management System), each collection on your site comes in two versions: a sandbox version for testing and a live version for your visitors. Both versions share the same structure but can hold different content.The sandbox collection is a test environment you use with the editor while building your site. Its content stays private until you decide to sync it with your live collection. This syncing process copies all content from the sandbox to the live collection, provided the sandbox is enabled. Remember, syncing can't be undone, so it's important to understand the differences between sandbox and live collections before proceeding.The live collection is what displays content on your live site for your visitors to see and interact with. When you sync the sandbox collection to the live collection, new items get added to the live collection, and updated items in the sandbox overwrite the same items in the live collection. However, if you remove an item from the sandbox and then sync, the item won't be removed from your live content.In this article, learn about:
