Available for Jekyll sites.
Provide default front matter and/or content for new drafts and collection items.
Defaults for collection item files are copied from _defaults.md in the root collection folder.
Defaults files are hidden in the Collections section to prevent changes from non-developers and clients.
Set the default extension for new files to .html by using _defaults.html instead.
For example:
/_staff/_defaults.mdcontains defaults for new staff members/_posts/_defaults.mdcontains defaults for new draft posts
New items created will use these values. If the title and name attributes are present, they are set to the name used when a user creates a file.
