Shadcn Primitives6 listings
This collection is limited to true headless libraries: unstyled, accessible components that handle behavior and focus management while leaving all visual design to you. shadcn/ui builds its components on top of these primitives and styles them with Tailwind CSS, so the primitive layer determines how dialogs, menus, popovers and selects behave.
