End of the insertion Begin of the deletion

End of the deletion ### Acceptance criteria (pre-refinement)

_Superseded by the scenarios above; kept for reference._

* Only cards the user is permitted to move can be selected. Attempting to select a non-movable card leaves the selection unchanged and is announced.

* On desktop:

* A plain click selects only that card and opens its details.

* **Ctrl/Cmd-click** toggles individual cards. The most recently selected or toggled card becomes the anchor for the next range.

* **Shift-click** selects a contiguous range from the anchor within the same list. Without an anchor, it selects only the clicked card and establishes it as the anchor.

* Keyboard users have equivalent selection controls: arrow keys move focus, **Space** toggles selection, **Shift+Space** or **Shift+Arrow** extends a range, **Ctrl/Cmd+A** selects all loaded movable cards, and **Escape** clears the selection. **Enter** opens card details.

* A sparse selection may span backlog and sprint lists, but a range cannot cross a list boundary or unloaded cards:

* **Shift-click** in a different list starts a new single-card selection there and establishes a new anchor.

* A range that would include unloaded cards is rejected: the existing selection and anchor stay unchanged, and the user is told to expand the list first.

* Modifier-based selection does not change the work package currently shown in the details pane.

* Dragging a selected card moves the full selection as one ordered block. Dragging an unselected card clears the previous selection and moves that card alone.

* Cards retain their visible top-to-bottom order at the destination, and the batch move succeeds or fails atomically as one operation.

* After a successful move, the selection is cleared. After a failed move, the cards remain selected and the move is reverted; if a concurrent update has already changed the lists, the user is told to check the current card positions instead.

* Opening the card menu on a selected card keeps the batch selection; opening it on an unselected card replaces the selection with that card. Applicable destination actions act on the batch. Positional actions are available only for one contiguous selection within one list.

* Pointer and keyboard selection behavior complies with the applicable WAI-ARIA APG multi-selection guidance.

* Selection state is communicated visually and accessibly; while multiple cards are selected, a visible count is shown. Keyboard users can perform the equivalent move through the card menu.


### Technical notes

* The interaction is informed by the [WAI-ARIA APG multi-select listbox pattern](https://www.w3.org/WAI/ARIA/apg/patterns/listbox/), but work package cards are not listbox options because they contain interactive descendants. Do not apply `role="listbox"`, `role="option"`, or `aria-selected`. Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Pointer and keyboard selection behaviour complies with the applicable WAI-ARIA APG multi-selection guidance. Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Builds on the drag-and-drop foundations delivered in #AGILE-291; batch move mechanics are tracked in #AGILE-278. Begin of the insertion


End of the insertion Begin of the deletion

End of the deletion ### Permissions and visibility considerations

* Only cards the user is currently permitted to move are eligible for selection. Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * The server re-authorizes every submitted work package. Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * If any submitted work package is invalid or unauthorized, the entire batch is rejected without partial movement (atomic) Begin of the insertion


End of the insertion Begin of the deletion

End of the deletion ### Translation considerations

* Selection and movement feedback must use translatable, plural-aware strings. This includes selected counts, selection rejection, successful movement, rollback or concurrent-update guidance, and work package counts shown in destination dialogs. Begin of the insertion


### Open decisions on behaviourEnd of the insertion

Begin of the insertionThese are potential follow-up changes, not approved acceptance criteria. The current behavior remains unless a decision below is explicitly adopted.

* **Shift into another list:** currently starts a new single-card selection and anchor. Consider preserving the existing batch and adding the endpoint instead. Any change must retain the single-item-type restriction; crossing into a different item type must not create a mixed batch.
* **Anchor moved to another list by a live update:** currently ends the range session and retains the selected cards. The next Shift gesture uses that selection as its baseline. Consider whether cards added only by the old range should instead be removed. This would change selection during reconciliation and needs explicit agreement.
* **Select-all scope and existing selections:** currently replaces the batch with loaded movable cards in the focused list. Consider whether retaining independent picks outside that list would be useful. Column-wide or progressive select-all would be separate decisions; neither is part of the current fix.

**Agreed correction in AGILE-361:** after Select All, Shift gestures can narrow or reverse the resulting range. Select All continues to replace the previous batch and stays list-scoped. Independently toggling a card afterwards starts a fresh range baseline in the usual way.

End of the insertion ### Out of scope

* Mobile and tablet long-press selection behavior, to be tracked in a deferred follow-up work package Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Migration of `wp-fast-table` or the Angular card view to the framework-agnostic selection model Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Direct keyboard grab and drop; equivalent movement remains available through the card menu Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Adding a visible drag handle; the whole card remains the pointer drag source Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Selecting work packages hidden behind truncation or filters Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * A separate **Ctrl/Cmd+Shift** range-selection mode. Ordinary Shift range selection already preserves independently selected cards as described in Scenario 3.
