Is it possible to create sub-subcategories?

[courtydrake (Courtney)]

Is it possible to create subcategories within subcategories? For example, can I have a grandparent category, parent subcategory, and child subcategory? If not, is there any alternative to creating a separate instance for each “grandparent”?

[codinghorror (Jeff Atwood)]

No, there are only two levels of categories in Discourse.

[jeans (Jens)]

We’ll combine the 2 levels of categories with tags. It’s not just about taxonomy, it’s also about moderation rights.

[justin_gordon]

Will 3 levels of categorization be possible in the future? My site is about 4 sports, then within each sport, I want a category called “Gear”, and then within “Gear” have the different brands.

I could also do a top level category called Gear, and then have the Gear Companies underneath.

Or just have the Gear companies for each sport listed directly under the sport.

[codinghorror (Jeff Atwood)]

No plans for more than 2 levels of categories. As @jeans noted, adding tags into the mix makes more sense at that point. So use the official tag support built into Discourse.

[jmay (Jason May)]

@codinghorror What would be the technical implications of allowing deeper nesting of categories? I don’t have a specific requirement in mind, just curious. I can see UI concerns, but the data model looks like it could handle chains of parents.

Here a typical case where we need to configure Discourse with 3 levels,
Local Groups - Open Knowledge Forums

the local-groups are in fact the “level zero”, in some cases we also change language (!), as at local-groups/okbr. The main topics are at this level-2, it is ok, but…

The level-3 is important to isolate very distinct topics and/or communities:

• to isolate official topics. Example: today we use the “official” tag as here, but we need to isolate as local-groups/okbr/oficial,

• to isolate projects, because they have independent communities and very specific topics. Example: this project was losted in an external category, openspending/gastos-abertos, we need an intersection between openspending and local-groups/okbr and we understand that the second is the priority, so need category local-groups/okbr/prj-gastos-abertos that is a typical “local group project” category.

This is interesting that have you decided that any existing field of knowledge may require to be split by exactly one level of categories but never by level two or higher. While I don’t know your exact reasoning but for me it’s very hard to believe that this can be the truth.

[codinghorror (Jeff Atwood)]

Two levels, not three. And we’re not the only people to think so.

We were very proud of our user interface and the fact that we had a way to browse 16,000 (!!) pages of documentation on a CD-ROM. But browsing the hierarchy felt a little complicated to us. So we asked Tufte to come in and have a look, and were hoping perhaps for a pat on the head or some free advice.

He played with our AnswerBook for about 90 seconds, turned around, and pronounced his review:

“Dr Spock’s Baby Care is a best-selling owner’s manual for the most complicated ‘product’ imaginable – and it only has two levels of headings. You people have 8 levels of hierarchy and I haven’t even stopped counting yet. No wonder you think it’s complicated.”

How can you actually tag a category?

[Menelaos_Viskadouros]

Olá, obrigado pela ótima ferramenta de discussão e comunidade. Gostaria de saber se há a possibilidade de criar sub sub categorias dinamicamente? Como isso pode ser feito com tags?

Agora você pode criar subcategorias, basta definir a categoria pai como a categoria sob a qual você deseja ter a subcategoria.

[JammyDodger]

É possível alterar o nível de subcategorias agora através de uma configuração oculta do site:

cd /var/discourse/

./launcher enter app

rails c

SiteSetting.max_category_nesting = 3

[merefield (Robert)]

Ele está se referindo a sub subcategorias, ou seja, um terceiro nível, não a um segundo nível (subcategorias).

[pfaffman (Jay Pfaffman)]

Certo. E essa configuração oculta possibilita ter Sub-Subcategorias (três níveis, daí o 3 na configuração). Já existia há um ano, eu acho, mas não teve muita divulgação quando foi adicionada (apenas apareceu nas notas de lançamento, mas talvez sem um título). Imagino que algum cliente corporativo deve ter solicitado o recurso, mas eles ainda acham que é uma má ideia.

[darkpixlz (Pyx)]

Nunca tentei criar uma sub subcategoria, não é possível através da interface do usuário?

[ClawdiaWolf (Claudia)]

@darkpixlz

Nunca tentei criar uma sub-subcategoria, não é possível através da interface do usuário?

É possível assim que o recurso for ativado. Você define o pai para a subcategoria em vez da categoria pai para criar uma sub-sub.

Esta é a aparência da tela de criação de categoria ao criar uma sub-sub:

Não me lembro quem pediu originalmente, mas pedimos para ativá-lo há pouco mais de um ano nos fóruns do NaNoWriMo na esperança de que eventualmente ajudasse a resolver um problema muito maior e um tanto único que temos.

Resolveu nosso problema de caso de teste, mas infelizmente nada menos que um milagre resolveria o outro problema.
