Barre latérale

Pour générer une barre latérale vers votre site Docusaurus :

  1. Spécifier un fichier exportant un objet de barre latérale.
  2. Pass this object into the @docusaurus/plugin-docs plugin directly or via @docusaurus/preset-classic.
docusaurus.config.js
module.exports = {
// ...
presets: [
[
'@docusaurus/preset-classic',
{
docs: {
// Sidebars filepath relative to the site dir.
sidebarPath: require.resolve('./sidebars.js'),
},
// ...
},
],
],
};

Objet de barre latérale#

A sidebar object contains sidebar items and it is defined like this:

type Sidebar = {
[sidebarId: string]:
| {
[sidebarCategory: string]: SidebarItem[];
}
| SidebarItem[];
};

Par exemple :

sidebars.js
module.exports = {
docs: [
{
type: 'category',
label: 'Getting Started',
items: ['greeting'],
},
{
type: 'category',
label: 'Docusaurus',
items: ['doc1'],
},
],
};

Dans cet exemple, notez ce qui suit :

  • La clé docs est l'id de la barre latérale. L'id peut être n'importe quelle valeur, pas nécessairement docs.
  • Getting Started is a category within the sidebar.
  • greeting and doc1 are both sidebar item.

La notation abrégée peut également être utilisée :

sidebars.js
module.exports = {
docs: {
'Getting started': ['greeting'],
Docusaurus: ['doc1'],
},
};
note

Shorthand notation relies on the iteration order of JavaScript object keys for the category name. When using this notation, keep in mind that EcmaScript does not guarantee Object.keys({a,b}) === ['a','b'], yet this is generally true.

Utiliser plusieurs barres latérales#

You can have multiple sidebars for different Markdown files by adding more top-level keys to the exported object.

Exemple :

sidebars.js
module.exports = {
firstSidebar: {
'Category A': ['doc1'],
},
secondSidebar: {
'Category A': ['doc2'],
'Category B': ['doc3'],
},
};

By default, the doc page the user is reading will display the sidebar that it is part of. This can be customized with the sidebar type.

For example, with the above example, when displaying the doc2 page, the sidebar will contain the items of secondSidebar only. Another example of multiple sidebars is the API and Docs sections on the Docusaurus website.

For more information about sidebars and how they relate to doc pages, see Navbar doc link.

Understanding sidebar items#

As the name implies, SidebarItem is an item defined in a Sidebar. A SidebarItem as a type that defines what the item links to.

type supports the following values

Linking to a doc page#

Set type to doc to link to a documentation page. This is the default type.

type SidebarItemDoc =
| string
| {
type: 'doc';
id: string;
};

Example:

{
type: 'doc',
id: 'doc1', // string - document id
}

Using just the Document ID is also valid, the following is equivalent to the above:

'doc1'; // string - document id

Using this type will bind the linked doc to current sidebar. This means that if you access the doc1 page, the sidebar displayed will be the sidebar that contains this doc page.

In the example below, doc1 is bound to firstSidebar.

sidebars.js
module.exports = {
firstSidebar: {
'Category A': ['doc1'],
},
secondSidebar: {
'Category A': ['doc2'],
'Category B': ['doc3'],
},
};

Creating a generic link#

Set type to link to link to a non-documentation page. For example, to create an external link.

type SidebarItemLink = {
type: 'link';
label: string;
href: string;
};

Example:

{
type: 'link',
label: 'Custom Label', // The label that should be displayed (string).
href: 'https://example.com' // The target URL (string).
}

Creating a link to page without sidebar#

Set type to ref to link to a documentation page without binding it to a sidebar. This means the sidebar disappears when the user displays the linked page.

type SidebarItemRef = {
type: 'ref';
id: string;
};

Example:

{
type: 'ref',
id: 'doc1', // Document id (string).
}

Creating a hierarchy#

The Sidebar item type that creates a hierarchy in the sidebar. Set type to category.

type SidebarItemCategory = {
type: 'category';
label: string; // Sidebar label text.
items: SidebarItem[]; // Array of sidebar items.
collapsed: boolean; // Set the category to be collapsed or open by default
};

Example:

sidebars.js
module.exports = {
docs: [
{
...
},
{
type: 'category',
label: 'Guides',
items: [
'guides/creating-pages',
{
Docs: ['docs-introduction', 'docs-sidebar', 'markdown-features', 'versioning'],
},
],
},
],
};

Note: it's possible to use the shorthand syntax to create nested categories:

sidebars.js
module.exports = {
docs: {
Guides: [
'creating-pages',
{
Docs: [
'docs-introduction',
'docs-sidebar',
'markdown-features',
'versioning',
],
},
],
},
};

Collapsible categories#

For sites with a sizable amount of content, we support the option to expand/collapse a category to toggle the display of its contents. Categories are collapsible by default. If you want them to be always expanded, set themeConfig.sidebarCollapsible to false:

docusaurus.config.js
module.exports = {
// ...
themeConfig: {
sidebarCollapsible: false,
// ...
},
};

Expanded categories by default#

For docs that have collapsible categories, you may want more fine-grain control over certain categories. If you want specific categories to be always expanded, you can set collapsed to false:

sidebars.js
module.exports = {
docs: {
Guides: [
'creating-pages',
{
type: 'category',
label: 'Docs',
collapsed: false,
items: ['markdown-features', 'sidebar', 'versioning'],
},
],
},
};

Hideable sidebar#

Using the enabled themeConfig.hideableSidebar option, you can make the entire sidebar hidden, allowing you to better focus your users on the content. This is especially useful when content consumption on medium screens (e.g. on tablets).

docusaurus.config.js
module.exports = {
// ...
themeConfig: {
hideableSidebar: true,
// ...
},
};

Passing custom props#

To pass in custom props to a swizzled sidebar item, add the optional customProps object to any of the items:

{
type: 'doc';
id: 'doc1';
customProps: {
/* props */
}
}
