Resizable

A draggable 1px hairline between panels, with a grip chip on the ones people are meant to notice. For lot list and lot detail layouts where panels genuinely trade space; the group itself never scrolls, its panels do.

<ResizablePanelGroup orientation="horizontal">
  <ResizablePanel defaultSize="60" minSize="20">Lot list</ResizablePanel>
  <ResizableHandle withHandle aria-label="Resize lot list and lot detail" />
  <ResizablePanel defaultSize="40" minSize="20">Lot detail</ResizablePanel>
</ResizablePanelGroup>
