# Matrix

The `Matrix` field allows you to set up a group of questions that all share the same options. They're represented in a tabular format, and you can also configure if your end-users can select multiple options per question.

The Feathery SDK and API reference pin input fields with `type` equal to `matrix`. The submitted value is of the format `{<question id>: [<selected option>]}`.
