As in title.

Is there any option to display item feed only if desired condition is true?

I see I can do kind of workaround by puting a container in "Show" and display this container only if condition is true but after linking it to "Feed" it still displays colums for hidden "Show items".

Or maybe there is another way to achieve something like public elements? The thing I want to achive is simple todo list but with owners and "isPublic" column/attribute. So if "isPublic" is true I want everyone to display this but if "isPublic" is false I want only owner can show/edit etc. this item.

Thanks for help in advance.
