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. |
