• Adds wrapper classes: spectrum-ActionMenu, spectrum-ActionMenu-trigger, spectrum-ActionMenu-popover, and spectrum-ActionMenu-menu.
• Supports long press triggers and four placements (start/end, top/bottom) via the underlying popover API.
• Design reference: Figma S2 token specs.

Migration notes

• If you previously composed an action menu manually (action button + popover + menu), you can adopt the new wrapper classes without changing the underlying markup semantics. Ensure the trigger has aria-haspopup="menu" and manages aria-expanded according to your application logic.
• For spacing customizations previously done with ad‑hoc margins, switch to the new --spectrum-actionmenu-button-to-menu-gap custom property.

Example markup:

<div class="spectrum-ActionMenu">
	<button
		class="spectrum-ActionMenu-trigger spectrum-ActionButton"
		aria-haspopup="menu"
		aria-expanded="false"
	>
		<!-- icon/label -->
	</button>
	<div class="spectrum-ActionMenu-popover spectrum-Popover">
		<ul class="spectrum-ActionMenu-menu spectrum-Menu">
			<!-- menu items -->
		</ul>
	</div>
	<!-- popover positioning/visibility is owned by your implementation -->
	<!-- use long-press behavior when appropriate to your UX -->
	<!-- use Popover placement options: bottom-start, bottom-end, start-top, end-top -->
</div>

Menu refinements

Updates @spectrum-css/menu styles to align with latest Spectrum 2 design specifications and improve accessibility.

• Updated .is-selectableMultiple .spectrum-Menu-itemCheckbox to .is-selectableMultiple:not(:has(.is-selectable)) .spectrum-Menu-itemCheckbox to prevent clash with the .is-selectable placement.
• Non-breaking; no class or DOM changes required.

Action button refinements

• Selection styling now applies when components use ARIA pressed/expanded semantics, not just .is-selected.
• Implemented with :where() to keep selector specificity low and prevent downstream specificity battles.
• Non-breaking; no class changes required.

Action group refinements

Aligns selection behavior of grouped items with action button updates.

• Adds :where([aria-pressed="true"], [aria-expanded="true"]) alongside .is-selected on items to cover more accessibility use-cases while keeping specificity low.
• Non-breaking; no class changes required.
