Feature request

It'd be nice to be able to expand collapse the root sidebar items.

Motivation

I have a site where the staging location has a site.baseurl and the live version has not. While working with inline images I found - by looking at the mmistakes codebase, could not discover instruction in the docs - that instead of this:

Hi;

I hope it's a feature request and not a bug report
I try to apply design.background but at the item level
and the code won't let me add more than one [design.background]

this is work

widget = "slider"
weight = 11
[[item]]
  title = "Left"
  content = "I am left aligned :smile:"
  [design.background]
    gradient_start = "#0000F9"
    gradient_end = "#86007D"

My apologies if this is trivial, I tried to find something on this in the documentation somewhere.

Essentially what I want is a way to simplify forwards/backwards navigation between posts by adding something like links labelled "Go to previous" on the top, and "Go to next" on the bottom, taking the reader to the respective previous pages.

I realized I can probably achieve something like this

What did you

Describe the solution you'd like
Add status to right of category. The category can often represent many systems so it would be awesome to see which category is operational, degraded or down.

This is in addition to the system status.

各位朋友，你们好。

如果你们使用 doocs/md 工具进行图文排版，欢迎在下方留言。后续我考虑在 README 首页中展示你们的公众号。谢谢你们 :D

i think the readme needs some refactoring now. It doesn't make sense anymore to instruct users to edit the variables in the script itself, especially considering how deeply buried those default values have gotten with the recent changes.

i'm thinking we merge the configuration and options sections, and the run section can be simplified, or maybe even mixed somewhere in with the rest, too.

overal

Generally, the following works as expacted:

• List IS-A Collection<E>

But for this particular case, it doesn't:

when you navigate to another page example "About" the menu feels like it is closed too fast and without progressive transition
