Creating dynamic categories without CMS

I am currently exploring whether Webflow is the right tool for me and my portfolio/business website. Seeing the functionality of CMS, pages, it’s looking like those will not be flexible enough to accommodate what I want to do with some of my portfolio items.

So I was wondering, if I make a ‘basic’ website, without CMS, would it in any way be possible to, for example, create page categories that will automatically show up in a list/menu of some sort? Or will I have to manually update my menu/portfolio page each time I want to add a new page?

(To get an idea of what I’d like to do, this is my current portfolio page. Many of the items are fairly simple in layout, but sometimes I want to create custom project overviews such as this one and this one)
