This component is managed in the company module, direct link to the company module:
The role module allows to define different roles for specific contact types. E.g. for different departments. In contrast to contacts roles have the possibility to inherit from other roles.
To add a role you can click on the "Create role" button which will open a new form. After submitting the creation form you will be forwarded to the role configuration.
After you created the role you can access multiple settings for the created role:
To remove roles you can use the trash button to delete the role which is no longer required.
The permissions of a role will be implicit inherit from other roles. E.g. (compared to the screenshot) The Role "Research & Development" inherits implicit the permissions of the roles "IT-Administration", "Technical Engineering" and "Product Development". If the "Technical Engineering" has the permission to edit order lists, the "Research & Development" role has no need to get these permission explicit. It is possible to drag'n'drop a role before, after or as a child role.
