As part of our progress with #41171 I was looking into aligning the sidebars to how it's implemented in Docsy. The sidebar in the Documentation page is pretty similar with some minor customisations but the one in the blogs page is pretty different.

• The top-level entries are a list of years

• There is no way to "expand" a year. Clicking on a year reloads the page with 10 blog entries shown in the sidebar and a "Show More Posts..." link, clicking on which loads all the posts in that year.

I was considering a rewrite of this sidebar to make it look and behave more like the sidebar in the Documentation page, which would mean that all the years will be "expandable" and the list of all the blog posts will be immediately shown without a "Show More" button or link.

Is that something that can be done or is there something I am overlooking?
