Show HN: A React layout component for proper staggered grid/Masonry layout

4 months ago 19

Sentereige is a React component library for creating interactive layouts with true masonry/grid systems. It handles nested structures and items with unknown dimensions, automatically packing items left-to-right in the shortest column while maintaining optimal spacing.

🖥️ Responsive Grid & List Layouts: Seamlessly adapt to any screen size for a polished user experience.
📦 Drag-and-Drop Sorting: Intuitive reordering of items within a single grid or list.
↔️ Multi-Grid Drag & Drop: Move items across multiple grids or lists with shared groupId.
🚀 Virtual Scrolling: Optimize performance for large datasets by rendering only visible items.
🛠️ Customizable Drag Handles: Define custom drag handles for tailored interactions.
