The Categories app allows you to create hierarchical categories and tag articles and content with them. When applied to content, categories create a taxonomy - a set of metadata that describes and classifies the content. Categories are displayed as links in the article header or as a weighted list known as a category cloud. By clicking category links, visitors can discover related content, resulting in more page views and longer stays on the site.
The Categories app is installed by the
module. The app is based on the
app framework so its configuration is typical of any content app. The
app is configured at Configuration >
The Categories app registers a custom
node type, and operates on
nodes of this type and on folders.
