Structured Snippets

A predefined header such as Services or Brands followed by a list of values, rendered as one line beneath a search ad.

You pick from Google's fixed header categories and then supply the list items, since the header itself cannot be custom. Formerly structured snippet extensions, they signal coverage, meaning which models, courses, or destinations you handle, rather than promoting a benefit. The mistake is confusing them with callouts: a list of unrelated marketing phrases under a category header reads as noise and can be disapproved.
