If you use multi sections (with the concept from hugo), the RSS at bottom and _Recent_ at side are ready for displaying those content. However, you will need to set up your menu at `config.toml` to point the hyperlink to proper destination.
If you want to re-order those sections, you need a `_index.md` at the directory of the section to set proper weight at front matter, just alike what was done at the exampleSite, see `/exampleSite/content/essays/_index.md`. See the predefined variable `weight` at [docs](https://gohugo.io/content-management/front-matter/#front-matter-variables).
**Note** that separating taxonomies according to different sections is not implemented yet. So better to only use taxonomies inside a specific section.
When you open the index page of _T1_, there will be two posts, rathor than post _A_ when you are in section _S1_ and post _B_ when you are in section _S2_.
The wordpress theme [Allium](https://wordpress.org/themes/allium/), and [here](https://templatelens.com/allium/) is its home page. I like this theme very much when I'm using wordpress, but I don't have it on hugo, so I try my best to write a theme similar with it. There are many designs in this theme refers to it.
