Certain user roles automatically grant access to modify templates, but you can allow content creators to modify content while restricting your templates from modification.
To make sure that your new collaborators do not inadvertently alter your templates, we recommend setting default roles for new content contributors and groups to Draft Author. You may also assign users and groups the role of Viewer, but you later will have to give them permission to author or edit content on pages.
To batch edit user roles, select multiple checkboxes to the left of the users and click Change Roles.
Users with Author, Editor or Admin roles will be able to access and modify the templates that you have created.
If you assigned users or groups Viewer roles in the control panel, but you want them to contribute to and collaborate on specific content, you need to grant them Author or Editor access on those pages:
Although you can apply permissions to all sub-pages, the higher in the hierarchy you apply permissions, the easier it will be to manage your permissions.
