# List schema

Learn how to define schemas for lists.

List schemas describe collections of items such as lists of tags, images, or products.

The input for a list schema is a list of fields that allows adding, removing, and reordering items.

You can also customize item labels to make the content easier to identify. By default, items are numbered sequentially (Item 1, Item 2, etc.), so renaming them helps you see what each one represents at a glance.
