Administrators have the option to view the user interface as it appears for a specific user or group based on their permission settings (Quality assurance of user/group permissions). The grayed-out folders shown below indicate that the user does not have access to them. This can help provide an overview of the permissions granted to a specific user or group. Please note that as a project user, your permissions may be limited within the project. The permissions for project users are defined based on the group they are invited to.
The overview can be found by clicking on Project Settings in the menu on the left -> Select Groups & Permissions.
NB! As a project user, you may have limited permissions on the project. The permissions for project users are defined based on the group they are invited to.
