Hi, I’m a bit confused.
When I post a category link from my forum on the same forum, no onebox shows up (but it works for other links, like a topic link):
But if I post a category link here, it works:
> **[Techniques et disciplines](https://forum.monocycle.info/c/techniques-et-disciplines/80)**
>
> Vous cherchez des conseils pour descendre d’un trottoir sans tomber ou venez nous faire découvrir les derniers tricks à la mode ?
> Vous cherchez une montagne pour de la descente en muni ? Vous voulez concevoir un circuit de longue distance à faire...
How do I make it work on my own forum?

Why not use the category tags (eg. #Support)?

How does this tag work? Is it just a #word with a link on it?
I like the oneboxes, they are pretty plus they display the category description.
Still, I don’t understand why oneboxing a category doesn’t work on my forum? 🤔

It is intentional
There isn’t much point duplicating description content around your own site. Your readers are already in your community. If there is value in them seeing a link to the category page then they can easily click through and visit that page.
On the other hand, if you are linking to a category on a DIFFERENT site, then maybe the reader wants to know more about what is on that page / site before making the commitment to click and leave your site. In that case there is value in showing a preview.
The way to create a useful link to a category page within a conversation is to:
- type `#` in the editor window (this cannot be the start of a new line but be inline as part of a sentence)
- search for the tag by starting to type, or select from the suggested shortlist
- select the relevant category (identified by the category title and colors)
So you can use this to link to categories (#Community Building) or tags (#tagging)
