I would like to divide my "Posts" section on my blog into subsections

Hi, I’m new to hugo and I would like to create a personal blog using the Paper theme.

I would like to have a “Posts” section on my website such that when I click on it, it open a submenu listing “A series of article related to one project” section, “Another series of article related to another projects”… and a section contening all my blog posts chronologically.

I’m doing this because I would like to have series of articles to different topics.

This is an example, from the hugoplate theme, of the king of submenu I’m talking about (in this case it’s the “Pages” section):
