Fields or tabs for public only

I may be tired but I cannot figure how can I make tabs or fields public eyes only ?
I mean only visible by the public but not by the registered members or higher group level ?

thanks

You need Joomla 2.5 or 3.0 for that.

Then define a Joomla public group (if on 2.5, as 3.0 has that group by default)
And define a Joomla access level for only that group.

Then use that access level in CB.

Well joomla 2.5 has also a public group !
Do you mean that we need to set up a second public group with another name ?

What we want is public eyes only, not registered or above

Exactly, Public-ONLY

What Beat is saying is you need to create a new Joomla ACL group outside the current tree. This is because in the current tree, Registered inherits the Public permissions.

Well I dont get this. If I set up a new public-only group it obviously become outside the current one, so CB config default to public does not allow to see this public-group tabs

Then if I change CB config for public-only, higher levels are not on the same tree then are not able to see tabs for registered , special or else.

So is it possible to change CB config to have public AND public-only by default ??
