IX-4363

💡 What is the current behavior?

  • Certain translations for weekdays get truncated
  • Using a custom weekStartIndex breaks the calender display in some months
  • Weekday translations always get sliced to 3 characters, even when it does not make sense in the locale
  • Endless scroll does not work with keyboard navigation
  • Selected months/years are not centered when opening their respective dropdown

GitHub Issue Number: #2591

🆕 What is the new behavior?

  • Use luxon 'short' and 'narrow' weekday names, depending on how much space the translation would use
  • Refactor calendar calculation
  • Fix endless scroll with keyboard navigation and avoid wrap around in the dropdown
  • Center month/year dropdown on the selected value on open

📝 Walkthrough

Walkthrough

This PR updates ix-date-picker weekday labels and calendar layout computation. It adds non-wrapping dropdown keyboard navigation and extends the year dropdown at its boundaries. Typings, changesets, styling, and regression tests are included.

Changes

Date Picker and Dropdown Keyboard Boundary Fixes

Layer / File(s) Summary
Boundary focus types and keyboard logic
packages/core/src/components/dropdown/dropdown-focus.ts
Adds boundary-navigation types and asynchronous callback handling for non-wrapping ArrowUp and ArrowDown behavior.
Dropdown and DropdownButton wiring and typings
packages/core/src/components/dropdown/dropdown.tsx, packages/core/src/components/dropdown-button/dropdown-button.tsx, packages/core/src/components.d.ts
Adds and forwards disableWrapFocusNavigation and onBoundaryFocus, with matching component and JSX typings.
Calendar layout and weekday rendering
packages/core/src/components/date-picker/date-picker.tsx, packages/core/src/components/date-picker/date-picker.scss, packages/core/src/components/date-picker/test/date-picker.ct.ts, .changeset/date-picker-translation-truncation.md, .changeset/date-picker-week-start.md
Uses adaptive weekday labels, full accessible labels, index-based calendar calculation, updated weekday styling, and regression coverage.
Year dropdown integration
packages/core/src/components/date-picker/date-picker.tsx, packages/core/src/components/date-picker/test/date-picker.ct.ts, .changeset/date-picker-year-dropdown-keyboard.md
Extends the year list at keyboard boundaries, focuses the new year, centers selected items, and tests ArrowDown behavior without wrapping.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🟡 Moderate · up to 90b4c

The PR improves localized weekday labels, custom week starts, and keyboard/dropdown behavior, but the current head can still show incorrect week information, misalign calendar headers after runtime configuration changes, and apply duplicate year-range updates during rapid keyboard input. These bounded UI and navigation issues make the PR not merge-ready until corrected or explicitly accepted.

Code Review

This pull request updates the date-picker component to use short weekday names directly and removes the associated overflow styling. However, the review feedback points out a critical bug where changing to short weekday names breaks the calendar calculation when weekStartIndex is not zero, due to string matching on long weekday names. A mathematical approach is recommended to resolve this. Additionally, a changeset is required for these user-facing changes per the repository style guide.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

In `@packages/core/src/components/date-picker/date-picker.tsx`:
- Around line 1096-1106: The weekday header list in the date picker can generate
duplicate VDOM keys when `setTranslations()` switches to narrow labels, since
`key={name}` may repeat across days. Update the `this.dayNames.map(...)` render
in `date-picker.tsx` to use a stable unique key based on the day position (for
example the `index`, or a composite key), so each weekday header remains
distinct across re-renders.

In `@packages/core/src/components/date-picker/test/date-picker.ct.ts`:
- Around line 278-301: Add a regression test for the double ArrowDown boundary
case in the date picker CT suite: the current ArrowDown-on-last-year test in the
date-picker test file only covers a single key press, but the review asks to
lock in the async boundary behavior noted in dropdown-focus.ts. Extend the
existing year-selection scenario by sending two ArrowDown presses back-to-back
without waiting between them at the last year boundary, and assert the focused
year advances correctly without re-entrant duplication or wrapping. Use the
existing regressionTest, yearSelection, and activeYear selectors to keep the
test close to the current coverage.

In `@packages/core/src/components/dropdown/dropdown-focus.ts`:
- Around line 211-234: The boundary-handling logic in the `ArrowDown` and
`ArrowUp` branches of `dropdown-focus.ts` is duplicated, so extract the repeated
index lookup, boundary check, `options.onBoundaryFocus` call, and
`setItemActive` update into a shared helper (for example inside
`handleDropdownFocus`) that accepts the direction and boundary condition. Then
have both branches call that helper so the `ArrowDown` and `ArrowUp` cases stay
aligned and only the boundary predicate differs.

In `@packages/core/src/components/date-picker/date-picker.tsx`:
- Around line 946-966: Update onYearDropdownBoundaryFocus to wait until the
target year dropdown item is present after changing startYear or endYear, rather
than relying on one waitForNextAnimationFrame call. Poll or await the rendered
target via the existing component/render lifecycle, and only call
findYearDropdownItem once the target item is available so boundary focus is not
lost.
- Around line 606-613: Update the weekNumber calculation in the
calendar-building method around calendar.push to derive the ISO week from a day
within the rendered row, preferably the row’s Thursday, rather than
firstDayOfWeek. Ensure Sunday-first rows still receive the ISO week number
belonging to that row, while preserving existing handling for rows without a
suitable day.

In `@packages/core/src/components/date-picker/test/date-picker.ct.ts`:
- Around line 19-28: Update getCalendarRows to use Playwright locator APIs for
row and gridcell traversal instead of evaluateAll and querySelectorAll. Preserve
the existing behavior of skipping the first row and returning each cell’s
numeric data-calendar-day value, while relying on locator-based reads for
auto-waiting and assertion diagnostics.

In `@packages/core/src/components/dropdown/dropdown-focus.ts`:
- Around line 152-183: Update handleBoundaryFocus to serialize concurrent
boundary-handling calls with an in-flight guard: return immediately when a

clear it after completion so later navigation can proceed. Preserve the existing
boundary checks, callback behavior, and active-item update.

in packages/core/src/components/dropdown/dropdown.tsx:185-191 and update
configureKeyboardInteraction wiring; make the same rename in
packages/core/src/components/dropdown-button/dropdown-button.tsx:109-116 and
update forwarding to ix-dropdown. Regenerate packages/core/src/components.d.ts

606-613: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Week numbers can mismatch the days shown in the same row.

weekNumber is computed from firstDayOfWeek, the first defined day in the row. Luxon's weekNumber follows the ISO week, which always starts on Monday. When weekStartIndex places Sunday in the first column, that Sunday belongs to the ISO week that precedes the ISO week of the remaining six days in the same row.

This is reachable with the fixtures already added in this PR: for weekStartIndex: -1, the row [6, 7, 8, 9, 10, 11, 12] (Sun–Sat) has Aug 6 in one ISO week and Aug 7–12 in the next. firstDayOfWeek picks Aug 6, so the row displays the wrong week number for six of its seven days when showWeekNumbers is enabled.

Derive weekNumber from a day nearer the middle of the row, for example the day at index 3, instead of the first defined day.

🐛 Proposed fix
-      const firstDayOfWeek = daysArr.find((day) => day !== undefined) ?? 1;
+      const midWeekDay =
+        daysArr[3] ?? daysArr.find((day) => day !== undefined) ?? 1;

       calendar.push({
         weekNumber: DateTime.utc(
           this.selectedYear,
           this.selectedMonth + 1,

Use the rendered dropdown-button refs for overlay checks.

yearMonthSelectionDropdownRef is never assigned. Its .current?.show checks in onKeyDown() and isCalendarDayFocused() therefore always report that the overlay is closed. Use monthDropdownButtonRef and yearDropdownButtonRef, or remove the unused ref and update both checks.
