I’d like to be able to style all tags within a certain tag group. It would be really handy if everywhere the tag-X CSS class exists, we could also have tag-group-X (where the tag belongs to a group.
In my local forum, I have tags for each road, all belonging to a group called “roads” - I’d like to be able to style all road tags, and avoid having to edit my CSS every time I add a new road tag.
Is this possible @neil?
We don’t fetch tag groups when rendering topics. They’re only useful when composing new topics. It’s technically possible, but can’t be done easily currently.
Hi, this might be cool logical feature. Currently Discourse has a great option Tag groups, but the ability to use its benefit like custom coloring for groups is missed now. If the group has it own class, it will be easy to apply single CSS for a group of tags.
For those who wants to apply custom style to some tag (css tag):
.tag-css.discourse-tag.box {
background-color: #ff9a1e;
color: #242424;
}
This request just came up in a discussion I was having. This site wants to color tags, but not need to modify their CSS every time a new tag is added, they’d prefer to simply add the tag to a tag group.
Sinto vontade de reativar este tópico 
Nosso caso de uso básico seria praticamente o mesmo mencionado aqui:
Mas também gostaríamos de poder fazer algumas mágicas com widgets baseadas em uma variável que retorna as etiquetas do tópico e seus respectivos grupos de etiquetas.
Adoraríamos ver isso também! Usamos um grande conjunto de tags para seções de diário/relatório. Seria legal ocultar alguns grupos de tags de /latest.
