@@ -109,6 +109,7 @@ Front matter variables have unique functions, including the following:
 - `hide-boilerplate`: defaults to false. When true, none of the content from `destination-footer.md` is appended to the destination page.
 - `hide-cmodes`: defaults to false. A renaming of "rewrite" for more clarity, hides the connection modes table in the boilerplate.
 - `hide-personas-partial`: defaults to false. When true, hides the section of content from `destination-footer.md` that talks about being able to receive personas data.
+- `hide_actions`: used to hide individual actions. Requires the `id` and `name` of each action.
 - `integration_type`: This is set in the `_config.yml` on three paths to add a noun (Source, Destination, or Warehouse) to the end of the title, and the end of the title tag in the html layout. It also controls the layout and icon for some of these.
 - `source-type`: These are only used to supplement when a Cloud App in the sources path doesn't appear in the Config API list, and needs its type explicitly set. It runs some logic in the `cloud-app-note.md` to explain which cloud-apps are object vs event sources.
 - `private`: Used to indicate that a destination is not publicly available (Private Beta or Pilot status), and is not available in the public catalog. When `private: true`, the build pulls integration metadata from `src/_data/catalog/destinations_private.yml`. To update the list of private destinations, use the `make private_destination` command, and enter the integration's ID when prompted.
