Implement sticky headers by wrapping header template parts in Group blocks since sticky positioning isn’t available directly on template parts. Set the Group to full width and enable sticky positioning.
The wrapper approach maintains proper header styling while adding sticky behavior. This technique works for any template part or block that needs sticky positioning functionality.
Test sticky headers on the frontend to ensure proper scroll behavior and visual appearance. The simple block-based approach eliminates complex CSS or JavaScript implementations.
This demonstrates how WordPress’s block system can implement advanced layout features through simple interface controls rather than custom development.
