Same Slack chat, we can push any content, only when create topic, user will create a topic in a category (in chanel)…  
But in Slack not filter by Subcategory, sub-sub category and tag  
And in homepage will display all chat of categories, parent category page will display all chat of this categroy and sub- categories, in sub categroy only display chat in that category.
