Question 1

How to make React-Grid-Layout responsive for different screen sizes?

Accepted Answer

Use the Responsive component or useResponsiveLayout hook with breakpoints and layouts per screen size, as demonstrated in the demos. You can define custom breakpoints like lg: 1200 and provide corresponding layout arrays for each.

Question 2

React-Grid-Layout vs CSS Grid: which should I use for a dashboard?

Accepted Answer

React-Grid-Layout is better for interactive, draggable/resizable widgets in React apps, while CSS Grid is sufficient for static layouts. If you need user customization and responsive breakpoints, React-Grid-Layout saves time over building from scratch.

Question 3

How to save and restore layouts in React-Grid-Layout?

Accepted Answer

Use the onLayoutChange callback to serialize the layout array to JSON and store it in localStorage or a backend. Restore by passing the saved layout prop, as shown in example 7 and 8 in the demos.

Question 4

Can I use React-Grid-Layout with Next.js for server-side rendering?

Accepted Answer

Yes, it's SSR compatible; use the measureBeforeMount option in the useContainerWidth hook to delay rendering until width is measured on the client, preventing hydration mismatches.

Question 5

How to customize drag handles or resize handles in React-Grid-Layout?

Accepted Answer

Set the handle property in dragConfig to a CSS selector (e.g., '.my-handle'), or provide a custom component via resizeConfig.handleComponent. This allows styling and behavior overrides for specific UI needs.

Question 6

What's the performance impact for dashboards with over 200 widgets?

Accepted Answer

For large layouts, use the fast compactors from the extras module to improve performance from O(n²) to O(n log n). The README includes benchmarks showing up to 74x speedup for horizontal compaction with 500 items.
