Setting up allowed content types for spaces
You can set which content types a space supports, and hide the others.
Fastpath
Admin Console: Spaces > Settings > Space Settings
Spaces can support a variety of content types, which you can configure. For example, by clearing the Documents check box, you'll remove the Create > Document link from the space's Actions list. In addition, users won't be able to select that space from the place picker before posting a new document.
warning
If users have created documents in the space already, and then you clear the Documents check box to remove support for them, existing documents will no longer be viewable in the space (although they'll still exist).
