PageHeader can be used to wrap masthead or hold a third-party custom header.

Fixes #12624

Assisted-by: Cursor

Tried to get it consistent with patternfly/patternfly#8567, but let me know if I'm missing something here.

Summary by CodeRabbit

  • New Features

    • Supports configurable HTML elements, CSS classes, child content, and additional properties.
    • Exported the component as part of the Page API.
  • Documentation

Walkthrough

Adds a public PageHeader component with configurable elements, classes, children, and forwarded props. Integrates it with the Page masthead prop, exports it from the Page barrel, and adds tests, documentation, an example, and package updates.

Changes

PageHeader masthead support

Layer / File(s) Summary
PageHeader component and public export
packages/react-core/src/components/Page/PageHeader.tsx, packages/react-core/src/components/Page/index.ts, packages/react-core/src/components/Page/__tests__/PageHeader.test.tsx
Adds PageHeader and PageHeaderProps. The component renders configurable elements, applies page-header styles, forwards props, and is exported publicly. Tests cover these behaviors.
Page masthead integration and validation
packages/react-core/src/components/Page/Page.tsx, packages/react-core/src/components/Page/__tests__/Page.test.tsx
Updates the masthead documentation to describe PageHeader as a wrapper for custom header content. Tests verify direct PageHeader rendering and remove the nested Masthead case.
PageHeader documentation and example
packages/react-core/src/components/Page/examples/Page.md, packages/react-core/src/components/Page/examples/PageHeaderContent.tsx
Documents PageHeader and adds an example with Masthead, branding, Toolbar, and PageSection content.
PatternFly version updates
packages/react-core/package.json, packages/react-docs/package.json, packages/react-icons/package.json, packages/react-styles/package.json, packages/react-tokens/package.json
Updates the PatternFly prerelease version from 6.6.0-prerelease.20 to 6.6.0-prerelease.39.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: 🔵 Low · up to a7922

PageHeader currently accepts a ref through its public props but does not forward it to the rendered element, which can break consumers relying on ref access. The PR is otherwise mergeable with explicit owner follow-up to align the ref behavior with the component contract.

Forward the ref to the rendered element.

PageHeaderProps accepts ref, but React 18 does not pass refs to this React.FunctionComponent. PageHeader therefore renders without attaching the ref, so ref.current remains unset. Wrap the component with React.forwardRef and pass the ref to Component. Add a test for the rendered element.
