Slab provides a flexible topic permission system to control a topic's read and edit permissions and the posts inside. The system also covers a wide range of access-level, allowing you to hide a topic from everyone or to share it with everyone on the Internet.
In this article, you will learn how Slab's topic permission works and how it affects the posts inside the topic.
Each topic has two permission-related settings:
Who can access: controls the visibility of the topic and its posts in your Slab organization
Members can edit...: controls what a topic member is allowed to do
Those two settings determine each team member's permissions based on user type and topic membership status. Admins can use their superpower to override any topic permission settings, except they need to be explicitly invited into a secret topic to see it.
Those settings are modified in topic settings.
Who can access setting
Regardless of user type, a member of a topic can always see the topic and its content. The topic's access level setting controls the visibility of the topic and its posts to non-members.
Access level setting also affects what types of subtopics are allowed – it wouldn't work if you try to have an Open topic underneath a Secret one.
All standard users and admins can see the topic and its posts.
It can have any type of subtopics.
All standard users and admins can see the topic's existence but not its content.
It can only have private or secret subtopics.
Non-members cannot see the topics' existence.
It can only have secret subtopics.
Anyone with the topic URL can see posts within without needing to log into Slab.
It can only have public subtopics.
Any teammate can be added to a topic. Topic membership has two levels: topic member and topic owner. Owners have all permissions to a topic, while members' permissions can be limited by the Member can edit... setting.
A subtopic can inherit its parent's membership, both the parents' members and owners. Topic owners can add or remove the inheritance.
It's possible to add a group to a topic. It's even possible to set the group as an owner. All group members share the same permission the group has.
Member can edit... setting
Owners can always edit everything. Members always have read permission for a topic. The Member can edit... setting only affects what a topic member can edit. Unlike the access level settings, the parent's setting value does not affect its subtopics.
There are 3 values for the setting:
Members can edit...
Topic members have both the topic and post edit permission. In this setting, the members have the same permission as owners besides not being able to promote a member to an owner.
Topic members have the post edit permission but not the topic.
Topic members only have read access to the topic and its posts.
