Layout System

Docs Layout

Standard documentation layout (sidebar + header + TOC):

import { DocsLayout } from 'fumadocs-ui/layouts/docs';
import { source } from '@/lib/source';

export default function DocsLayout({ children }: { children: React.ReactNode }) {
  return (
    <DocsLayout
      tree={source.getPageTree()}
      sidebar={{ enabled: true }}
      header={{ title: 'My Documentation' }}
    >
      {children}
    </DocsLayout>
  );
}

Sidebar Configuration

<DocsLayout
  tree={source.getPageTree()}
  sidebar={{
    enabled: true,
    tabs: true, // Enable tabs
    collapsible: true, // Collapsible
    defaultOpenLevel: 2, // Default open level
    prefetch: true, // Prefetch
  }}
>
  {children}
</DocsLayout>

Sidebar Breadcrumb

<DocsLayout
  tree={source.getPageTree()}
  sidebar={{
    enabled: true,
    banner: <div>Welcome to our docs!</div>,
  }}
>
  {children}
</DocsLayout>

Flux Layout

Minimalist layout, suitable for technical blogs:

import { FluxLayout } from 'fumadocs-ui/layouts/flux';
import { source } from '@/lib/source';

export default function FluxLayout({ children }: { children: React.ReactNode }) {
  return (
    <FluxLayout tree={source.getPageTree()}>
      {children}
    </FluxLayout>
  );
}

Home Layout

Homepage layout, ideal as a website entry point:

import { HomeLayout } from 'fumadocs-ui/layouts/home-layout';

export default function HomeLayout({ children }: { children: React.ReactNode }) {
  return (
    <HomeLayout>
      {children}
    </HomeLayout>
  );
}

Notebook Layout

Notebook-style layout, compact for technical documentation:

import { NotebookLayout } from 'fumadocs-ui/layouts/notebook';
import { source } from '@/lib/source';

export default function NotebookLayout({ children }: { children: React.ReactNode }) {
  return (
    <NotebookLayout tree={source.getPageTree()}>
      {children}
    </NotebookLayout>
  );
}

Search UI

Basic Search Dialog

'use client';
import { SearchDialog, SearchDialogList } from 'fumadocs-ui/components/dialog/search';

export default function SearchDialog() {
  const { search, setSearch, query } = useDocsSearch();

  return (
    <SearchDialog search={search} onSearchChange={setSearch}>
      <SearchDialogList items={query.data} />
    </SearchDialog>
  );
}

import {
  SearchDialog,

export default function CustomSearchDialog() {
  const { search, setSearch, query } = useDocsSearch();
  const [isFocused, setIsFocused] = useState(false);

  return (
    <SearchDialog search={search} onSearchChange={setSearch}>
      <SearchDialogOverlay className={isFocused ? 'opacity-100' : 'opacity-0'} />
      <SearchDialogContent className={isFocused ? 'scale-100' : 'scale-95'}>
        <SearchDialogHeader>
          <SearchDialogIcon />
          <SearchDialogInput />
          <SearchDialogClose />

} from 'fumadocs-ui/components/dialog/search';
import { useState } from 'react';

export default function TagFilterSearchDialog() {
  const [tag, setTag] = useState<string | undefined>();

  const { search, setSearch, query } = useDocsSearch({
    tag,
  });

  return (
    <SearchDialog search={search} onSearchChange={setSearch}>
      <SearchDialogOverlay />
      <SearchDialogContent>
        <SearchDialogHeader>
          <SearchDialogIcon />

            <TagsListItem value="getting-started">Getting Started</TagsListItem>
            <TagsListItem value="api">API Reference</TagsListItem>
            <TagsListItem value="guides">Guides</TagsListItem>
          </TagsList>
        </SearchDialogFooter>
      </SearchDialogContent>
    </SearchDialog>
  );
}

    <SearchDialog search={search} onSearchChange={setSearch}>
      <SearchDialogOverlay />
      <SearchDialogContent>
        <SearchDialogHeader>
          <SearchDialogIcon />
          <SearchDialogInput />

          renderItem={(item) => (
            <div className="p-4 border-b">
              <h3 className="font-semibold">{item.title}</h3>
              <p className="text-sm text-muted-foreground">{item.description}</p>
              <Link href={item.url} className="text-blue-500">
                Read more →
              </Link>
            </div>
          )}
        />
      </SearchDialogContent>
    </SearchDialog>
  );
}

Theme Configuration

Basic Configuration

// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        fd: {
          primary: '#3b82f6',
          secondary: '#64748b',
          accent: '#f59e0b',
          background: '#ffffff',
          foreground: '#0f172a',
          muted: '#f1f5f9',
          'muted-foreground': '#64748b',
          border: '#e2e8f0',
        },
      },
    },
  },
};

Base UI vs Radix UI

Default uses Radix UI:

import { RootProvider } from 'fumadocs-ui/provider/nextjs';

<RootProvider>
  {children}
</RootProvider>

Switch to Base UI:

// cli.json
{
  "uiLibrary": "base-ui"
}

CSS Variable Customization

Fumadocs uses CSS variables for color customization:

:root {
  --fd-primary: #3b82f6;
  --fd-secondary: #64748b;
  --fd-accent: #f59e0b;
  --fd-background: #ffffff;
  --fd-foreground: #0f172a;
  --fd-muted: #f1f5f9;
  --fd-muted-foreground: #64748b;
  --fd-border: #e2e8f0;
  --fd-sidebar-width: 280px;
  --fd-header-height: 60px;
}
