FAQ

How can I fix layout/sizing problems with conditionally rendered panels?

The Panel API doesn't require id and order props because they aren't necessary for static layouts. When panels are conditionally rendered though, it's best to supply these values.

 order={1}>
        
      
      
    
  )}
  
    

  

How can I use persistent layouts with SSR?

By default, this library uses localStorage to persist layouts. With server rendering, this can cause a flicker when the default layout (rendered on the server) is replaced with the persisted layout (in localStorage). The way to avoid this flicker is to also persist the layout with a cookie like so:

Server component

import ResizablePanels from "@/app/ResizablePanels";
import { cookies } from "next/headers";

export function ServerComponent() {
  const layout = cookies().get("react-resizable-panels:layout");

  let defaultLayout;
  if (layout) {
    defaultLayout = JSON.parse(layout.value);
  }

  return ;
}

Client component

"use client";

import { Panel, PanelGroup, PanelResizeHandle } from "react-resizable-panels";

export function ClientComponent({
  defaultLayout = [33, 67]
}: {
  defaultLayout: number[] | undefined
}) {
  const onLayout = (sizes: number[]) => {
    document.cookie = `react-resizable-panels:layout=${JSON.stringify(sizes)}`;
  };

  return (
    
        {/* ... */}
      
      
      
        {/* ... */}
      
    
  );
}

A demo of this is available here.
