Create relationships between content
Tags are used to create relationships between content in the CMS. Tags are organized into tag groups for logical separation and are used by creating tag fields which can hold any number of tags from a specific or non-specific tag groups. The relationships created by tagging content can then be leveraged via methods on content in your templates.
Tags consist of:
Handle (for querying and template access)
Tag groups consist of:
Name and handle (for querying and template access)
Entries (whether or not entries should be created for tags in the tag group. This allows for fields and layouts to be applied to tags in the group)
