Review Change Stack

Walkthrough

Compass, Page, and NavExpandable now support controlled dock expansion and expandable navigation icons. Docked navigation examples add expandable groups, dismissal handling, updated icons, and related documentation. The helpers barrel exports inert.

Changes

Docked navigation expansion

Layer / File(s) Summary
Navigation component contracts
packages/react-core/src/components/Compass/Compass.tsx, packages/react-core/src/components/Nav/NavExpandable.tsx, packages/react-core/src/components/Compass/__tests__/*, packages/react-core/src/components/Nav/__tests__/*
Adds isDockExpandableExpanded and hasExpandableIcon. Tests cover enabled, disabled, and default behavior.
Dock layout expansion
packages/react-core/src/components/Page/Page.tsx, packages/react-core/src/components/Page/__tests__/Page.test.tsx
Page applies the expandableExpanded modifier when enabled. Tests cover dock and masthead rendering.
Docked navigation examples
packages/react-core/src/components/Nav/examples/NavDocked.tsx, packages/react-core/src/demos/Compass/examples/CompassDockDemo.tsx, packages/react-core/src/demos/examples/Nav/NavDockedNav.tsx
Examples add expandable groups, coordinated dock state, outside-click and Escape dismissal, updated breakpoints, and controlled expansion props.
Navigation example assets and documentation
packages/react-core/src/components/Nav/examples/Nav.md, packages/react-core/src/components/Nav/examples/NavIcons.tsx, packages/react-core/src/demos/Compass/Compass.md, packages/react-core/src/demos/Nav.md
Examples use Red Hat UI icons and document docked navigation expansion and hasExpandableIcon usage.

Helper maintenance

Layer / File(s) Summary
Inert helper export
packages/react-core/src/helpers/index.ts
Re-exports the inert helper module.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 7f71e

This PR adds expandable behavior to docked navigation. Current behavior can leave the dock visually expanded after closing a group, require an extra click after dismissal, or apply expandable styling when no dock content exists; these are bounded UI correctness issues, so the change is mergeable with explicit owner follow-up.

Clear expandable dock state when the navigation group closes.

When the user closes Policy on desktop, result.isExpanded becomes false but both handlers retain isDockExpandableExpanded. The Page or Compass dock then remains expanded while the subnavigation is hidden.

  • packages/react-core/src/demos/examples/Nav/NavDockedNav.tsx#L232-L245: Set isDockExpandableExpanded from result.isExpanded when isDockTextExpanded is false.
  • packages/react-core/src/demos/Compass/examples/CompassDockDemo.tsx#L122-L135: Apply the same state transition.
Proposed fix
-      if (!isDockExpandableExpanded && !isDockTextExpanded) {
-        setIsDockExpandableExpanded(true);
-      }
-
       if (!isDockTextExpanded) {
-        setIsDockTextExpanded(false);
+        setIsDockExpandableExpanded(result.isExpanded);
       }

This pre-exists your work, but there is a bug between 992 to 1200px viewports in the docked nav demo where the ellipsis icon stops showing and you can't expand the nav. Mobile is fine and the larger size is fine.

Compass is fine - I think we want to reuse globalBreakpointLg for the mobile breakpoint.

Everything else looks good to me! ✨

This looks great! Just one small thing. Could we add tooltips to the expandable item and the subnav item?

Clear the group state when a dismiss action closes the dock.

On desktop, Folder can remain expanded after Escape or an outside click. The next Folder click then closes the group and reopens an empty expandable dock. Reset isNavGroupExpanded with the dock state.

Gate this modifier on dockContent.

The prop documentation says it applies only when dock content is passed, but Line 381 checks only isDockExpandableExpanded. A docked Page without dockContent can therefore apply expandable styling to an empty dock. The equivalent logic in packages/react-core/src/components/Compass/Compass.tsx is inside the dock && branch.

Add a content guard and a regression test for a docked page without dockContent.
