Update CMS items

Update CMS items

Updates the fields of one or more items in a CMS collection, holding changes to published items in draft until they are published.

On the MCP server, use the update_collection_items action of data_cms_tool with collection_id and each item's id and fieldData; the CLI updates one item at a time with --collection, --item and --data. A published item keeps its live version and shows "Changes in draft" until you publish it, so follow an update with a publish when the change should go live.
