Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Inaccessible custom select Flag this anti-pattern when a custom dropdown cannot be opened, navigated, selected, dismissed, and reviewed by keyboard. The trigger exposes an accessible name, current value, role, and expanded or collapsed state. Carbon documents multi-select dropdown behavior with selected tags, removal, filtering, clear-all, and multiple selection modes.
Multi-select Choose multi-select for long, searchable, or compact multi-choice sets where a visible checkbox group would be too large. Users can search, add, and remove values without losing their current selection. Carbon multiselect guidance supports checkbox options, persistent open menu while selecting, selected-count tags, clear-all behavior, and filtering.
