docs(action-bar): Expand accessibility section for AI codegen - #4189
Conversation
Align Button docs with the Canvas Kit accessibility template: structure, built-in behaviors, requirements table, and anti-patterns scoped to variant buttons with correct Segmented Control and icon-only naming guidance. Co-authored-by: Cursor <cursoragent@cursor.com>
Expand the Action Bar accessibility docs to match the Button/Menu pattern: minimum structure, built-in behaviors (overflow, keyboard, screen reader), requirements table, and anti-patterns. Make plain MDX table cells opaque in Storybook so inline code is distinguishable from zebra striping. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Make the no-design-spec example safe for page layout.
ActionBar.List defaults to position: fixed at the viewport bottom. The minimum example and no-design-spec instruction provide no reserved space, so generated layouts can cover bottom content or focused controls. Set position="relative" in the minimum example and require it in the no-design-spec guidance.

Disable unavailable actions in the overflow menu too.
When a disabled action overflows, the model does not transfer its disabled state to ActionBar.Menu.Item. The menu counterpart can therefore invoke the same handler. Require aria-disabled on the menu counterpart. Menu.Item uses this attribute to prevent onClick and onSelect; do not use native disabled on the menu item.
Suggested documentation update
-| Disabled action _(conditional)_ | Native **`disabled`** on **`ActionBar.Item`** when the spec marks the action unavailable |
+| Disabled action _(conditional)_ | Native **`disabled`** on **`ActionBar.Item`** when the spec marks the action unavailable; when the action overflows, use **`aria-disabled`** on its **`ActionBar.Menu.Item`** counterpart |📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Summary
Resolves: N/A (docs initiative: accessibility guidance for AI codegen)
Rewrites the
## Accessibilitysection ofActionBar.mdxto follow the pattern used by the Button and Menu docs: intro and related-component links, minimum accessible structure, built-in behaviors (including overflow, keyboard, and screen reader expectations), an accessibility requirements table with a "no design spec" default and REQUIRED/CONDITIONAL summary, and anti-patterns. Every ARIA/focus claim was checked againstmodules/react/action-bar/liband the Menu/collection hooks. The Open/close focus table is omitted because Action Bar is not an overlay.Also adds a small Storybook docs style (
.storybook/preview-head.html) that makes plain MDX table cells opaque. Storybook's zebra striping used the same color as inlinecode, so code pills were indistinguishable in the new requirements table. The Component API tables already had opaque cells, so this makes the MDX tables consistent with them.Release Category

This branch is stacked on the Button accessibility rewrite (docs(button): Expand accessibility section for AI codegen #4183), so the diff also shows
Button.mdx. That file will drop out once docs(button): Expand accessibility section for AI codegen #4183 merges.The
.storybook/preview-head.htmlrule affects every plain MDX table in Storybook docs; please confirm that is acceptable.Design-system page guidance was not fetched; behavior is derived from source.
Testing Manually
Run
yarn start, open Components / Buttons / Action Bar / Docs, and review the Accessibility section: tables render with opaque cells, inline code is distinguishable, and links resolve (Modal and Dialog links in particular).Summary by CodeRabbit
