Recently a bug was introduced when the admin sidebar section was made bold.
When the admin sidebar is disabled, we display the original sidebar in the admin panel. In that case, an incorrect CSS rule is executed.
```CSS
.admin-area .sidebar-wrapper {
background-color: var(--d-sidebar-admin-background);
.sidebar-section-header-text {
font-weight: bold;
}
}
```
Bug in this PR: https://github.com/discourse/discourse/pull/26801
To solve it, a custom CSS class with a panel key was added which will allow granular customisations.
NOTE: Most of this is experimental and will be removed at a later
time, which is why things like translations have not been added.
The new /admin-revamp UI uses a sidebar for admin nav. This initial
step adds a script to generate a map of all the current admin nav
into a format the sidebar to read. Then, people can experiment
with different changes to this structure.
The structure can then be edited from `/admin-revamp/config/sidebar-experiment`,
and it is saved to local storage so people can visually experiment with different ways
of showing the admin sidebar links.
This commit adds a new admin UI under the route `/admin-revamp`, which is
only accessible if the user is in a group defined by the new `enable_experimental_admin_ui_groups` site setting. It
also adds a special `admin` sidebar panel that is shown instead of the `main`
forum one when the admin is in this area.
We also add an "Admin Revamp" sidebar link to the community section, which
will only appear if the user is in the setting group:
Within this there are subroutes defined like `/admin-revamp/config/:area`,
these areas could contain any UI imaginable, this is just laying down an
initial idea of the structure and how the sidebar will work. Sidebar links are
currently hardcoded.
Some other changes:
* Changed the `main` and `chat` panels sidebar panel keys to use exported const values for reuse
* Allowed custom sidebar sections to hide their headers with the `hideSectionHeader` option
* Add a `groupSettingArray` setting on `this.siteSettings` in JS, which accepts a group site setting name
and splits it by `|` then converts the items in the array to integers, similar to the `_map` magic for ruby
group site settings
* Adds a `hidden` option for sidebar panels which prevents them from showing in separated mode and prevents
the switch button from being shown
