• Headless: dnd-timeline is a headless-ui library, and contains 0 styling, aside from functional styling (position, z-index, etc.).
• Hook-based: exposes simple hooks like useItem and useRow, that should integrate seamlessly into your existing architecture.
• Flexible: very slim and flexible by design. dnd-timeline exposes utility functions and positional styling, and you can use them in conjunction with you favorite libraries - styling libraries (MUI, tailwindcss, ant-design, etc.), and functional libraries (react-virtual, framer-motion, etc.)
• Based on dnd-kit: all features exposed by the dnd-kit library are applicable to dnd-timeline.
• Performant: renders only when needed. All the intermediate states and animations are done using css transformations, and require 0 re-renders.
