# Theme Configuration

The theme is configured with the theme.config.jsx (opens new window) file. It should export an object that contains your configurations, for example:

export default {
  logo: <>
    <svg width="24" height="24" viewBox="0 0 24 24">
      <path
        fill="currentColor"

# Global

# Docs Repository

Set the repository URL of the documentation. It’s used to generate the “Edit this page” link and the “Feedback” link.

Option	Type	Description
docsRepositoryBase	`string`	URL of the documentation repository

# Specify a Path

If the documentation is inside a monorepo, a subfolder, or a different branch of the repository, you can simply set the docsRepositoryBase to the root path of the pages/ folder of your docs. For example:

export default {
  docsRepositoryBase: 'https://github.com/shuding/nextra/tree/main/docs'
}

Here is another example:

export default {
  docsRepositoryBase: 'https://github.com/ULL-MII-SYTWS-2425/nextra-casiano-rodriguez-leon-alu0100291865/blob/main/',
}

Then Nextra will automatically generate the correct file path for all pages.

# Head Tags

Configure the <head> tags of the website. You can add meta tags, title, favicon, etc.

Option	Type	Description
head	`React.ReactNode \\| React.FC`	Component that renders the `<head>` content

# Static Head Tags

If you have only static head tags, it’s easy to directly put them in head. For example:

export default {
  head: (
    <>
      <meta name="viewport" content="width=device-width, initial-scale=1.0" />
      <meta property="og:title" content="Nextra" />
      <meta property="og:description" content="The next site builder" />
    </>
  )
}

# Dynamic Tags Based on Page

You can also use a function component as head to dynamically generate the head tags based on the current page’s front matter. For example:

import { useRouter } from 'next/router'
import { useConfig } from 'nextra-theme-docs'

export default {
  head() {
    const { asPath, defaultLocale, locale } = useRouter()
    const { frontMatter } = useConfig()
    const url =
      'https://my-app.com' +
      (defaultLocale === locale ? asPath : `/${locale}${asPath}`)

    return (
      <>
        <meta property="og:url" content={url} />
        <meta property="og:title" content={frontMatter.title || 'Nextra'} />
        <meta
          property="og:description"
          content={frontMatter.description || 'The next site builder'}
        />
      </>
    )
  }
}

# Search

`banner.dismissible`	`boolean`	Closable banner or not
`banner.key`	`string`	Storage key to keep the banner state (dismissed or not)
`banner.content`	`React.ReactNode \\| React.FC`	Content of the banner

A banner can be dismissed. By default banner.key will be "nextra-banner" and it’s used by localStorage (opens new window) to keep the banner state (dismissed or not) on the client.

If you have updated your banner text, you should change the key to make sure the banner is shown again. The best practice is to always use a descriptive key for the current text, for example:

import bannerImage from 'public/assets/docs/banner.png'

export default {
  banner: {
    key: '2.0-release',
    content: (
      <a href="https://nextra.site" target="_blank">
        🎉 Nextra 2.0 is released. Read more →
      </a>
    )
  }

Option	Type	Description
navbar.component	`React.ReactNode \\| React.FC<NavBarProps>`	Navbar component
navbar.extraContent	`React.ReactNode \\| React.FC`	Display extra content after last icon

Option	Type	Description

sidebar.autoCollapse	`boolean`	If true, automatically collapse inactive folders above `defaultMenuCollapseLevel`
sidebar.toggleButton	`boolean`	Hide/show sidebar toggle button. Defaults to `false`

By default, the sidebar menu is collapsed at level 2. You can change it by setting sidebar.defaultMenuCollapseLevel to a different number. For example, when set to 1, every folder will be collapsed by default and when set to Infinity, all nested folders will be expanded by default.

If sidebar.autoCollapse is set to true, then all folders that do not contain an active/focused route will automatically collapse up to the level set by sidebar.defaultMenuCollapseLevel. e.g. if defaultMenuCollapseLevel is 2, then top-level folders will not auto-collapse.

# Customize Sidebar Content

Together with the [Separators]https://nextra.site/docs/docs-theme/page-configuration#separators) item, you can customize how the sidebar content is rendered by using JSX elements:

export default {
  index: 'Intro',
  '--': {
    type: 'separator',
    title: (
      <div className="flex items-center gap-2">
        <MyLogo />
        {children}
      </div>
    )
  },
  frameworks: 'JS Frameworks & Libs',
