Multi-select dropdown

Searchable multiple-value picker with chips, select-all rules, keyboard support and scalable option loading.

Current-state summary

Multi-select dropdown appears across the current product but is not yet governed as one fully documented reusable component. Project Opportunity matching fields and collaborator checkboxes support multiple values, but there is no one chip, search, select-all, maximum-count or remote-loading pattern.

Anatomy and verified behavior

Verification states separate observed behavior from requirements or assumptions.

ElementCurrent behaviorVerification
Canonical interactionUse a searchable multi-combobox for scalable lists and checkbox groups only for short visible sets. Show selected values as removable chips or a compact count with an accessible full summary. Define select-all scope, maximum selections, ordering, duplicate prevention, clear-all and retired-option behavior.Required reusable contract
Data contractStore ordered or unordered relationships explicitly according to field definition; never comma-join values into one string.Required shared storage and API behavior
AccessibilityAnnounce each add/remove, result count and selection count; chips and clear controls are keyboard reachable with non-colour state cues.Required before component is approved for reuse

User journeys

Current flows

01

Use Multi-select dropdown

  1. Render from the shared component registry
  2. Load canonical value and configuration
  3. Accept keyboard, pointer or assistive-technology input
  4. Validate and normalize
  5. Persist canonical value with provenance
  6. Render the same meaning in profiles, grids, filters, exports and integrations
Observed result

This is the required cross-product journey; implementation consistency varies today.

State model

Current and expected states

Default

Value can be entered or selected with a visible label.

Focused

Must provide a visible focus indicator without layout shift.

Disabled or read-only

Must distinguish unavailable input from view-only canonical value.

Required or optional

Requirement is communicated in label, schema and validation—not colour alone.

Invalid or warning

Inline message explains the problem and preserves the user’s input where safe.

Loading or saving

Async work prevents duplicate commands and remains announced.

Empty or cleared

Null, empty string, zero and empty collection retain distinct meanings.

Product rules

Non-negotiable boundaries

  • Build once and reuse the same component, schema and formatter in every Workspace experience.
  • Display formatting is separate from canonical storage.
  • Every value has a stable field key, type, validation, privacy classification and version.
  • Client validation improves usability; server validation remains authoritative.
  • Equivalent values render consistently in forms, grids, profiles, filters, exports, notifications and documents.
  • Use a searchable multi-combobox for scalable lists and checkbox groups only for short visible sets.
  • Show selected values as removable chips or a compact count with an accessible full summary.
  • Define select-all scope, maximum selections, ordering, duplicate prevention, clear-all and retired-option behavior.

Future alignment

Required evolution

  • 01Promote this pattern into the approved component library.
  • 02Replace local copies incrementally and retain migration adapters only where required.
  • 03Add automated interaction, validation, accessibility and serialization tests.
  • 04Track reuse across: services needed, rooms, specialties, languages, Provider Categories, Task collaborators, Teams, report filters.

Current baseline

Acceptance record

  • The component has one public API and canonical data contract.
  • All required states are documented and tested.
  • Formatting and validation are consistent across every consumer.
  • Keyboard and screen-reader testing passes.
  • Existing inconsistent copies have an owner and migration plan.

Reverse-spec completeness

Documentation coverage

The interface is still changing, so visual evidence and repository tracing remain intentionally incomplete.
