You can display any data of the category that the article belongs to.
To simply show the name of the category:
{article title="Lions"}[category]{/article}
Also, [category-id] will output the ID of the category, while [category-alias] will output the alias.
With the Pro version of Articles Anywhere, you can also output the [category-url], and automatically link to the category page with:
[category-link][category][/category-link]
Parent Category PRO
The same exact data can also be output for the Parent Category of an article, by using [parent-category] instead of [category].
