This is a simple component that adds a menu of parent category links to the site header, with horizontally scrolling overflow added if/when needed.

This is really cool - I love it, Kris! It will combine with the sidebar beautifully, allowing the core cats up top and a short personalised selection on the bar.
Iāve noticed two little UX issues that could really give it a lift if addressed:
When on a category list, the correct category has a lovely subtle underline.
However, this doesnāt persist if a Topic or a subcategory is entered.
It would be lovely if it did persist in both of those situations.
There is a nice little fade / subtle arrow visible when there is overflow of the categories on desktop.
Overflow is much more likely on mobile, but on my device (Chrome / Android) these subtle cues are not present - and it isnāt clear that scrolling is possible.
It might also help to have the categories bar a little taller on mobile to make scrolling easier.
Another couple of UX issues on mostly applying to mobile:
In mobile topic views, the breadcrumb navigation clashes with the categories navbar:
Also, the category selected isnāt scrolled to automatically - this means that it is not apparent that it is selected unless the user scrolls the Navbar. This is vital really.
I do wonder if it isnāt really ready for mobile yet, and it would be really handy to have a setting to only apply it to desktop (at least for now).
Thanks for the quick feedback! Iāve merged in some updates that should address these.
Brilliant - very happy to give feedback when it is listened to! Youāve had to make quite a few additions to it I note.
Iāll take that as a nice little Christmas 
to one another 
.
Youāve fixed this when a Subcategory has been entered - wonderful!
However, it does not apply when a topic is entered - is that deliberate? Personally, I believe that it would make sense if the category stays highlighted while the user is āinā it, which includes the topics and not just the category discovery views.
Also, when I enter another page (such as /admin) the category remains selected. It would be better if no category was selected in this case.
I can see the fade on mobile now, but not an arrow / chevron. If possible this would be super helpful as the fade is pretty damn subtle:
Desktop: 
Mobile: 
Hide the Navbar when scrolling in a topic. It all gets a bit busy!
Also, it might be better on desktop to have the Navbar located where the breadcrumb / tags are in that image instead of below them.
Could you please add a CSS class to each Nav Pill so it would be easy to hide some if needed?
I ask because I have a couple of (private) parent categories which are only parents in order to enable subcategories, and they clutter up the general navigation in an undesirable way.
Iāve hidden these for now using their href, but that is of course pretty dicey!
An option to sort Sidebar Categories alphabetically.
As Iām implementing this, Iāve removed the parent categories from the default sidebar categories list. This means that my users now have just a list of 1-5 subcategories that are relevant to them.
However, they are a bit scrambled and in no logical order as the order on /Categories for subs doesnāt really make sense . It would be very helpful for these subcats to be alphabetic to help this!!
Thanks for reporting! this should fix it:
Works perfectly. Thanks!
Hello! First of all, I would like to note that this is a very useful component of the topic and I want to thank you for the work you have done 
On my instance, this component caused an error, I checked for compatibility with other plugins and theme components and at this point I have not yet found a conflict. Could the component itself be the cause?
Enabling this component distorts the presentation of the content.
Hereās a video:
In order to detect an error, you need to click on any post from the latest posts page /latest, the post will open in standard mode, then you need to go back to the latest posts page.
@Aizada_M - I canāt seem to reproduce this. Is this happening to you when you preview from the component?
Greetings! Sorry for the long response
I didnāt use the preview, I tested it with the component enabled.
This works 100% of the time when I click on the category name under the topic title.
Iāve noticed that the text in the Head Categories Navbar suddenly changed to font-up-1 (whereas I think it was font-down-1 before). This is quite jarring and unpleasant, as it is the same as all the other nav pills.
Iāve over-ridden it with this CSS, which is much more pleasing:
// fixes text size of header navbar
.custom-categories-navbar .nav-pills>li>a {
font-size: var(--font-0);
}
I prefer font-0 actually as it is different enough and a bit easier to use.
The core CSS did not change, and the component does not set the font size. 
Maybe you had custom CSS before?
Love this TC, thank you! Would be great to customize which items do and do not appear!
I love it but the theme component seems broken in the latest version of discourse
EDIT: itās works fine, but needed to desactive āchatā and āDark-Light Toggleā icons in the header
yes itās because of my logo. If i cut it a little bit, its works with chat and dark-light toggle. I"m using:
.d-header #site-logo {
max-height: 30px;
}
for now
Hey, i just saw a bug now, you can reproduce like that. On mobile:
1- Click on one category in the header
2 - Click on one post in the category and Scroll at the end
3 - Click on the same category on the header
All the category header will disappear. I just tryed it on my forum and on the demo
EDIT:
itās the same if you go to a category and refresh( f5) the page. All category will disappear.
EDIT:
Is there any fix for it? Thanks
