CMS: Deleting Fields from a Collection
You can delete a field from your CMS (Content Management System) collection if you no longer need the field or its stored values. Make sure the field is not used in any datasets, SEO settings, or connected page elements before you delete it to avoid breaking connections. To prevent broken URLs for dynamic pages, you cannot delete a field if it's used in the dynamic page's URL slug structure. Tips:

You can also create manual backups whenever you want to instantly save a copy of all your collections. Each backup includes all your collections' content, structure fields, settings, and named views. When you restore a backup, you choose whether to restore all your collections or specific ones. Restoring a collection permanently deletes any changes made to the collection after the backup was created. This includes site visitor submissions saved after the backup date. What happens to my CMS collection if I restore my site from site history?Restoring your site from site history reverts your site to a previous version but does not affect CMS collections. Wix apps, including the CMS, store their data in the apps themselves instead of in your site history. Your collections remain intact, even if you restore your site to a version that didn't have the CMS installed.
