WAI-ARIA role button on tr table row semantics aria-expanded treegrid table row accessibility
💡 Result:
Adding role="button" to a table row (tr element) is not recommended and negatively impacts accessibility [1][2][3]. Using this role on a tr element can remove the row from the accessibility tree in some screen readers, causing users to lose both the semantic information of the row and its functionality [2]. Regarding aria-expanded and treegrid semantics: 1. Treegrid Usage: The aria-expanded attribute is specifically valid for rows (tr) or their cells when they are part of a treegrid [4][5]. In a treegrid, this attribute indicates whether a parent row is expanded or collapsed to show or hide child rows [6][5]. 2. Standard Table/Grid Usage: Using aria-expanded on a tr element within a standard table or grid (role="table" or role="grid") is incorrect [4]. These attributes have no function in standard tables and can cause unpredictable behavior in assistive technologies [4]. 3. Accessibility Best Practices: - Avoid making entire table rows interactive by adding roles like "button" [7][2]. - Instead, place interactive controls (such as actual button or link elements) inside the cells of the row [7][2]. This approach ensures standard behavior, proper focus management, and better compatibility across different browsers and screen readers [2][8]. - If you need a tabular structure with expandable rows, implement the treegrid pattern correctly, ensuring the container has role="treegrid" and follow WAI-ARIA authoring practices for keyboard interaction and state management [4][6]. In summary, do not add role="button" to a tr, and reserve aria-expanded for genuine treegrid implementations where row expansion is natively supported by the design pattern [2][4].

Move the disclosure control out of the <tr>
role="button" on the row can strip table semantics from the accessibility tree, and aria-expanded belongs on a real treegrid pattern. Put a <button> in a cell, or switch the whole table to treegrid.

🔵 INFO: No tests exist for SessionHooksPanel component. The new keyboard accessibility behavior (tabIndex, onKeyDown, aria-expanded) should ideally have test coverage:
- Test that Enter/Space toggles row expansion
- Test that aria-expanded reflects correct state
- Test that tabIndex makes rows focusable
Consider adding tests in tests/components/session-hooks-panel.test.tsx.

⚠️ Issues Found
- 🟡 Accessibility —
app/components/session-hooks-panel.tsx:333—role="button"on a<tr>is discouraged by WAI-ARIA. See inline comment for alternatives (treegrid pattern or native button in td). - 🔵 Info —
__tests__/components/session-hooks-panel.test.tsx— No tests exist for this component. Keyboard behavior should be tested. See inline comment.
🔬 Logical / Bug Analysis
- onKeyDown handler: Correctly uses
e.key === "Enter" || e.key === " "' for Space (literal space character).e.preventDefault()` prevents browser scroll on Space. ✅ Correct. - aria-expanded: Correctly bound to
isExpandedstate. ✅ Correct. - aria-hidden on chevron: Prevents double announcement. ✅ Correct.
- No async/await or race conditions: The toggleRow handler is synchronous. ✅ Safe.
- No resource leaks: No timers, subscriptions, or connections to leak. ✅ Safe.

🔗 Issue Linkage
This PR addresses #525 — "Dashboard Hook Logs table rows are not keyboard-accessible". The changes add keyboard focusability (tabIndex), Enter/Space toggling (onKeyDown), and screen reader announcement (role=button, aria-expanded, aria-hidden on chevron). All three requirements from the issue description are satisfied.
👥 Human Review Feedback
No human review comments on this PR. One CodeRabbit bot thread about role="button" accessibility — noted in inline comment, left open for maintainer decision.
💡 Suggestions
- Consider adding
data-testidattributes (data-testid="hook-row-expand") to make future test authoring easier. - The single-line ternary in onKeyDown is dense — extracting a
handleKeyDownfunction would improve readability if more keys are added in the future.

Tabbed through it — Enter/Space toggles and aria-expanded flips correctly, and hiding the chevron from AT is a nice touch.

Thanks for taking this on — the gap is real and your fix does work. I ran it (tsc, lint, 2233 tests, build all green, only the pre-existing #569 failure) and rows are focusable and Enter/Space toggles them.
I'd like to talk you out of the specific approach before it lands, though.
Putting role="button" on the <tr> overrides its implicit row role. ARIA wants cell elements owned by a row, and rowgroup (the <tbody>) to contain rows — so once the role is overridden, all nine <td>s are orphaned from the table's accessibility tree. A screen reader user loses the ability to navigate the data column by column and instead gets the whole row flattened into one button label. Given the columns here are Decision / Event / Tool / Policy / Reason / Duration / Mode / Time, that's a fair amount to lose in exchange for the keyboard fix. It's a bit of a "fixed one a11y problem, opened another" situation.
The issue's first suggestion sidesteps it — make the chevron cell a real button and leave the row as a row:
<td className="px-4 py-2">
<button
type="button"
onClick={() => toggleRow(i)}
aria-expanded={isExpanded}
aria-label={`${isExpanded ? "Collapse" : "Expand"} hook event details`}
className="..."
>
<ChevronDown aria-hidden="true" className={...} />
</button>
</td>You get keyboard operability, a proper expanded-state announcement and a real focus ring, and the table keeps its semantics. Keep the onClick on the <tr> as a mouse convenience if you like — it just stops being the only way in.
Two smaller things while you're in here:
There are no tests. __tests__/components/ already has the setup you'd need (Vitest + Testing Library, 10 files — copy-button.test.tsx is a decent template). Worth covering: the control is reachable by Tab, Enter and Space each toggle, and aria-expanded follows the state.
And app/policies/hooks-client.tsx:677 has the identical mouse-only expandable row. Strictly outside #525, but you're already in this code and otherwise the next person fixes the same thing twice.
Ping me when you've had a look and I'll turn it around quickly. Appreciate you picking up the a11y work — it usually sits untouched.

Closing this one for now — but I'd genuinely like you to pick it back up, so let me explain rather than leave you guessing. The keyboard part of your fix was right. Rows were mouse-only, and The problem was where the role went. Putting The version I'd merge is the issue's first suggestion — put a real <td className="px-4 py-2">
<button
type="button"
onClick={() => toggleRow(i)}
aria-expanded={isExpanded}
aria-label={`${isExpanded ? "Collapse" : "Expand"} hook event details`}
className="..."
>
<ChevronDown aria-hidden="true" className={...} />
</button>
</td>Keyboard operability, a proper expanded-state announcement, a real focus target — and the table stays a table. Keep the existing Two things that would make it a complete fix:
#525 is open and unassigned, so it's yours if you want it — reopen this PR with the change or open a fresh one, whichever you prefer. Happy to review quickly either way. Thanks for taking on the a11y work in the first place; it's the kind of thing that usually sits in the backlog forever. |
|
Thanks for the detailed explanation, that makes total sense — role="button" on the breaking table semantics is exactly the kind of thing that's easy to miss. Going to pick it back up with your suggested approach:
I'll re-open this PR shortly with the changes applied. |

I've applied the changes as suggested.
Could you reopen the PR when you get a chance? |
