Design and implement a filter pattern

[daniellecorke]

Background

This issue has been split from #2815. We would like to introduce a filter pattern to the Design System. This will provide a new pattern that will be beneficial to users and reduce burden on designers and developers in teams using the Design System.

User Story

AS A Design System user I WANT a readily available filter pattern SO THAT I can efficiently implement a consistent and accessible filter within my design

Acceptance Criteria

SCENARIO 1: GIVEN a user is on the Design System webpage WHEN they click 'patterns' THEN they find a filter pattern with examples and code that can be copied

Info

• A filter pattern may have previously been designed by Lauren for Author and by Digital Publishing. In the first instance, contact wider ONS colleagues for information as this ticket may not require extensive design work.
