📝 Walkthrough

The dropdown adds panel sizing, tree and checkable-item semantics, projected headers and separators, and configurable icons for item values. Tests and Storybook examples cover these additions and related keyboard, focus, and presentation behavior.

Changes: Dropdown

Layer / File(s) Summary
Panel sizing and integration
package.json, src/tedi/components/overlay/dropdown/dropdown.component.ts, src/tedi/components/overlay/dropdown/dropdown.component.html, src/tedi/components/overlay/dropdown/dropdown.component.scss, src/tedi/components/overlay/dropdown/dropdown.component.spec.ts, src/tedi/components/overlay/dropdown/dropdown.stories.ts
The dropdown accepts width and maximum-height settings and applies them to the panel. The tests and stories cover sizing, placement, and trigger behavior. The core dependency is pinned to version 6.9.1.
Tree and checkable-item behavior
src/tedi/components/overlay/dropdown/dropdown.tokens.ts, src/tedi/components/overlay/dropdown/dropdown-content/*, src/tedi/components/overlay/dropdown/dropdown-item/*, src/tedi/components/overlay/dropdown/dropdown.component.spec.ts, src/tedi/components/overlay/dropdown/dropdown.stories.ts
Items support tree indentation and connector styling. Checkbox and radio items expose role-specific ARIA states, including mixed checkbox state. Selection and multiselectable behavior varies by dropdown role.
Headers, separators, and focus handling
src/tedi/components/overlay/dropdown/dropdown-content/*, src/tedi/components/overlay/dropdown/dropdown-header/*, src/tedi/components/overlay/dropdown/dropdown-separator/*, src/tedi/components/overlay/dropdown/dropdown.component.ts, src/tedi/components/overlay/dropdown/dropdown.tokens.ts, src/tedi/components/overlay/dropdown/dropdown-trigger/dropdown-trigger.directive.ts, src/tedi/components/overlay/dropdown/dropdown.stories.ts, src/tedi/components/overlay/dropdown/index.ts
Dropdown content projects headers and separators and supports divided styling. Header keyboard handling moves focus to the first item or closes the dropdown and returns focus to the trigger. Separator roles depend on the dropdown role.
Item-value controls and examples
src/tedi/components/overlay/dropdown/dropdown-item-value/*, src/tedi/components/overlay/dropdown/dropdown-item/dropdown-item.component.scss, src/tedi/components/overlay/dropdown/dropdown.stories.ts
Item values accept icon names or option objects, with default size and color values. Checkbox and radio inputs use inert. Tests and stories cover icons and item states.

Merge Risk: 🔵 Low · up to fa892

A dropdown with no value can set an unexpected initial active item when some items have no value. The effect is small and easy to fix, so the PR is mergeable with this follow-up.

Security architecture risk: 🔵 Low · up to fa892

The changes remain within dropdown presentation, selection and focus handling. No introduced security attack path was established in the inspected code. The expanded public interfaces carry limited integration risk, and downstream application behavior remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is browser-side presentation, focus and local selection for consuming dropdown instances. The inspected additions do not themselves grant service, tenant or data-store authority. Applications may attach their own actions to selection events; those downstream effects were not established by repository evidence.

Trust Boundaries and Controls

  • observed — The pre-existing disabled-item capture handler and activation guards remain in place while the PR changes role and selection announcements. These controls suppress local UI activation; they are not application authorization checks.

Review comments at
@src/tedi/components/overlay/dropdown/dropdown-item/dropdown-item.component.ts:
- Around line 262-265: Update setActiveToSelectedOrFirst to identify the
selected item using item.isSelected() rather than comparing item.value()
directly with the dropdown value. This ensures value-less items are not treated
as selected when the dropdown value is unset, so the method falls back to the
first enabled item.

Review comments at @src/tedi/components/overlay/dropdown/dropdown.stories.ts:
- Line 705: Rename the `WithDecription` story export to `WithDescription` so
Storybook displays the correctly spelled name in the sidebar.
