- Yes its possible to provide read-only access to dashboard only in a folder
An Access Control List (ACL) model is used to limit access to the dashboard folders.
A user can be assigned permissions to a folder or to a single dashboard. For more information, see the
Folder Permissions section.
If a user has editor access and the admin wants to grant only viewer access, the admin must first remove the existing edit access
before adding view access to that user since higher access takes precedence.
Also granting permission at the folder level automatically applies to all dashboards in that folder,however
Admin can modify permissions at the dashboard level.
2 . No its not possible to provide read-only access to particular chosen dashboard panels
Permissions are only supported at dashboard and folder level and not at the dashbaord panel level
