Header Layout
Control the header container with useFlexLayoutControl. Collapse the header based on the scroll direction and maintain the current exposure ratio on route changes.
root/head structure
To control the header, it must be configured as FlexLayoutContainer. Typically, place a head container inside the root layout, and compose the rest of the screen with a body container.
Control the Header
In the Header component, pass the current pathnameand the hide condition. Connect the returned contentRefto the actual header content wrapper.
Collapse on scroll
enableScrollHideOnScrollto trueWhen enabled, the header container collapses when scrolling down and expands again when scrolling up or returning to the top of the page.

If you need to explicitly hide or show the header on a specific route, pass that condition hideContaineras. If the value is truetrue, the header container collapses, and if the value is falsefalse, the header container expands. In both cases, scroll-based automatic collapsing/expanding is disabled.

params
layoutName
제어할 container가 들어 있는 decomposition layout 이름입니다. header 예시에서는 root를 사용합니다.
containerName
flex-grow로 제어할 decomposition container 이름입니다. header 예시에서는 head를 사용합니다.
pathname
route 변경을 감지하고 현재 main-axis 노출 비율을 새 route에 동기화하는 데 사용합니다.
hideContainer
대상 container의 표시 상태를 명시적으로 제어하는 tri-state 값입니다. true이면 강제 숨김, false이면 강제 표시, null/undefined이면 명시적 제어 없이 enableScrollHideOnScroll 설정을 따릅니다.
enableScrollHideOnScroll
hideContainer가 null/undefined일 때 scroll 방향에 따라 대상 container를 자동으로 접거나 복원할지 여부입니다. hideContainer가 true 또는 false이면 이 설정은 적용되지 않습니다.
containerSizeKeyName
측정된 container main-axis size를 저장할 global-rx-state key입니다.
containerSizeStorageOptions
container size state에 적용할 global-rx-state storage 옵션입니다.
return value
contentRef
실제 content size를 측정할 wrapper에 연결하는 ref입니다.
