This question is more about professional advice, than programming. That said, yes - there's zero reason not to list projects that may never be directly viewable.
If you're concern is showing like work, well guess the first thing you need to realize is that when you take on work like this, there a tradeoff in the overall value of the project to you long term. Just like if you were to work on an open source project where it would be okay to not only see the website, but the code behind it; for example, Ruby Koans (GitHub) and Ruby Koans (Online).
The phrase "like this project not in online" is unclear to me, since it might mean you're attempting to compare the work to work you did, or that it's like someone's work that is online that's not yours; don't compare your work to others, just cite your own as best as possible. I'd suggests something like:
- Project-Name-01 (www.name.com)
- Project-Name-02 (offline)
Just to be clear, I'm NOT saying how to organize/present the information, only to add the metadata of a URL or 'offline' to your existing project metadata.
