How does Netlify CMS handle mutiple sub pages and blog post,

The blue box will be shown in the appbar of the site. And they will be presented all the time. The green box will be shown as dropdown list on the site. And when a user click the 1st two green box they will be presented a page that lists out all the red box where they can select which chapter they wanna read.

I will be adding more sub pages as my blog grow. And those sub pages will have its own pages. (a.k.a those red box, they act like chapter divider for their parent pages)

Can Netlify CMS handle this kind of blog where there will be many sub pages and pages under it?

I am new to build a CMS on my own. Sorry if this question seems noob.
