Let me ask you a simple question.

[ghost]

I happened to see a blog and was fascinated by how it works similar to notion, so I started using gitbook. But I wanted to make the sublist look like the picture above, but I failed. How can I organize my writing like the picture above?

I tried using url but failed to make it the same.

And I'm not a programmer.
Still, can I organize the list of posts like the first picture?
