To open groups click Security > Groups. A list of all groups is displayed on the right side. You can search for existing groups, edit them, add a new member or create a new group.
Clicking the + button displays a modal window where a new group can be created.
Clicking on a group name from a page extends to two lists that contain users and projects belonging to that group.
You can add or remove users from the selected group.
To add a new user to a group, use the search field located at the top of the list. A search of users can be done by name, surname, or email address. If the user you searched for is already in the database and has not been previously assigned to a group, they can be added to the group by clicking the + button. If you want to delete a user from the group when you hover over the user name with the mouse, the "bin" icon will appear on the right side, by clicking on it, the user will be removed from the group.
