--- template: overrides/main.html --- # Setting up navigation A clear and concise navigation structure is an important aspect of good project documentation. Material for MkDocs provides a multitude of options to configure the behavior of navigational elements, including [tabs][1] and [sections][2], and its flag-ship feature: [instant loading][3]. [1]: #navigation-tabs [2]: #navigation-sections [3]: #instant-loading ## Configuration ### Instant loading [:octicons-file-code-24: Source][4] · :octicons-unlock-24: Feature flag When _instant loading_ is enabled, clicks on all internal links will be intercepted and dispatched via [XHR][5] without fully reloading the page. Add the following lines to `mkdocs.yml`: ``` yaml theme: features: - navigation.instant ``` The resulting page is parsed and injected and all event handlers and components are rebound automatically. This means that __Material for MkDocs behaves like a Single Page Application__, which is especially useful for large documentation sites that come with a massive search index, as the search index will now remain intact in-between document switches. _Material for MkDocs is the only MkDocs theme offering this feature._ [4]: https://github.com/squidfunk/mkdocs-material/blob/master/src/assets/javascripts/integrations/instant/index.ts [5]: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest ### Navigation tabs [:octicons-file-code-24: Source][6] · :octicons-unlock-24: Feature flag When _tabs_ are enabled, top-level sections are rendered in a menu layer below the header for viewports above `1220px`, but remain as-is on mobile.[^1] Add the following lines to `mkdocs.yml`: [^1]: Prior to version 6.2, navigation tabs had a slightly different behavior. All top-level pages (i.e. all top-level entries that directly refer to an `*.md` file) defined inside the `nav` entry of `mkdocs.yml` were grouped under the first tab which received the title of the first page. This made it impossible to include a top-level page (or external link) as a tab item, as was reported in #1884 and #2072. From version 6.2 on, navigation tabs include all top-level pages and sections. ``` yaml theme: features: - navigation.tabs ``` === "With tabs" [![With tabs][7]][7] === "Without tabs" [![Without tabs][8]][8] [6]: https://github.com/squidfunk/mkdocs-material/blob/master/src/partials/tabs.html [7]: ../assets/screenshots/navigation-tabs.png [8]: ../assets/screenshots/navigation.png #### Sticky navigation tabs [:octicons-file-code-24: Source][9] · :octicons-unlock-24: Feature flag · :octicons-beaker-24: Experimental · [:octicons-heart-fill-24:{: .tx-heart } Insiders only][9]{: .tx-insiders } When _sticky tabs_ are enabled, navigation tabs will lock below the header and always remain visible when scrolling down. Just add the following two feature flags to `mkdocs.yml`: ``` yaml theme: features: - navigation.tabs - navigation.tabs.sticky ``` === "With sticky tabs" [![With sticky tabs][10]][10] === "Without sticky tabs" [![Without sticky tabs][11]][11] [9]: ../insiders.md [10]: ../assets/screenshots/navigation-tabs-sticky.png [11]: ../assets/screenshots/navigation-tabs-collapsed.png ### Navigation sections [:octicons-file-code-24: Source][12] · :octicons-unlock-24: Feature flag When _sections_ are enabled, top-level sections are rendered as groups in the sidebar for viewports above `1220px`, but remain as-is on mobile. Add the following lines to `mkdocs.yml`: ``` yaml theme: features: - navigation.sections ``` === "With sections" [![With sections][13]][13] === "Without sections" [![Without sections][8]][8] [12]: https://github.com/squidfunk/mkdocs-material/blob/master/src/partials/nav-item.html [13]: ../assets/screenshots/navigation-sections.png Both feature flags, _tabs_ and _sections_, can be combined with each other. If both feature flags are enabled, sections are rendered for level 2 navigation items. ### Navigation expansion [:octicons-file-code-24: Source][12] · :octicons-unlock-24: Feature flag When _expansion_ is enabled, the left sidebar will expand all collapsible subsections by default, so the user doesn't have to open subsections manually. Add the following lines to `mkdocs.yml`: ``` yaml theme: features: - navigation.expand ``` === "With expansion" [![With expansion][14]][14] === "Without expansion" [![Without expansion][8]][8] [14]: ../assets/screenshots/navigation-expand.png ### Section index pages [:octicons-file-code-24: Source][9] · :octicons-unlock-24: Feature flag · :octicons-beaker-24: Experimental · [:octicons-heart-fill-24:{: .tx-heart } Insiders only][9]{: .tx-insiders } When _section index pages_ are enabled, documents can be directly attached to sections, which is particularly useful for providing overview pages. Add the following lines to `mkdocs.yml`: ``` yaml theme: features: - navigation.indexes ``` === "With section index pages" [![With expansion][15]][15] === "Without section index pages" [![Without expansion][16]][16] In order to link a page to a section, create a new document with the name `index.md` in the respective folder, and add it to the beginning of your navigation section: ``` yaml nav: - Section: - section/index.md - Page 1: section/page-1.md ... - Page n: section/page-n.md ``` _This feature flag can be combined with all other feature flags, e.g. [tabs][1] and [sections][2], except for table of contents [navigation integration][17]. Note that it doesn't rely on third-party plugins[^2]._ [^2]: If you don't want to use the native integration, the [mkdocs-section-index][18] plugin might be an alternative. However, note that this plugin may not be compatible with all navigation-related features offered by Material for MkDocs.

For some languages, the default may not produce good and readable identifiers – consider using another slug function like for example those from [Python Markdown Extensions][22]: === "Unicode" ``` yaml markdown_extensions: - toc: slugify: !!python/name:pymdownx.slugs.uslugify ``` === "Unicode, case-sensitive" ``` yaml markdown_extensions: - toc: slugify: !!python/name:pymdownx.slugs.uslugify_cased ``` `toc_depth`{: #toc_depth } : :octicons-milestone-24: Default: `6` – Define the range of levels to be included in the table of contents. This may be useful for project documentation with deeply structured headings to decrease the length of the table of contents, or to remove the table of contents altogether: === "Hide levels 4-6" ``` yaml markdown_extensions: - toc: toc_depth: 3 ``` === "Hide table of contents" ``` yaml markdown_extensions: - toc: toc_depth: 0 ``` Note that MkDocs will not generate [anchor links][23] for levels outside the range defined with `toc_depth`. However, Material for MkDocs also allows to [hide the table of contents][24] on a specific page while keeping permalinks. _Material for MkDocs doesn't provide official support for the other options of this extension, so they may be supported but can also yield weird results. Use them at your own risk._ [19]: https://github.com/squidfunk/mkdocs-material/blob/master/src/partials/toc.html [20]: https://python-markdown.github.io/extensions/toc/ [21]: https://python-markdown.github.io/extensions/toc/#usage [22]: https://facelessuser.github.io/pymdown-extensions/extras/slugs/ [23]: #permalink [24]: #hide-the-sidebars #### Navigation integration [:octicons-file-code-24: Source][25] · :octicons-unlock-24: Feature flag When _integration_ is enabled, the table of contents is rendered as part of the navigation for viewports above `1220px`, but remains as-is on mobile. Add the following lines to `mkdocs.yml`: ``` yaml theme: features: - toc.integrate ``` === "Integrate table of contents" [![Integrate table of contents][26]][26] === "Separate table of contents" [![Separate table of contents][8]][8] [25]: https://github.com/squidfunk/mkdocs-material/blob/master/src/assets/stylesheets/main/layout/_nav.scss [26]: ../assets/screenshots/toc-integrate.png The content section will now always stretch to the right side, resulting in more space for your content. This feature flag can be combined with all other feature flags, e.g. [tabs][1] and [sections][2]. ### Hide the sidebars [:octicons-file-code-24: Source][27] · :octicons-note-24: Metadata Sometimes it's desirable to hide the navigation and/or table of contents sidebar, especially when there's a single navigation item. This can be done for any page using the [Metadata][28] extension: ``` yaml --- hide: - navigation # Hide navigation - toc # Hide table of contents --- ... ``` === "Hide navigation" [![Hide navigation][29]][29] === "Hide table of contents" [![Hide table of contents][30]][30] === "Hide both" [![Hide navigation and table of contents][31]][31] [27]: https://github.com/squidfunk/mkdocs-material/blob/master/src/base.html [28]: ../../reference/meta-tags/#metadata [29]: ../assets/screenshots/hide-navigation.png [30]: ../assets/screenshots/hide-toc.png [31]: ../assets/screenshots/hide-navigation-toc.png ## Customization ### Keyboard shortcuts [:octicons-file-code-24: Source][32] · :octicons-mortar-board-24: Difficulty: _easy_ Material for MkDocs includes several keyboard shortcuts that make it possible to navigate your project documentation via keyboard. There're two modes: `search`{: #search } : This mode is active when the _search is focused_. It provides several key bindings to make search accessible and navigable via keyboard: * ++arrow-down++ , ++arrow-up++ : select next / previous result * ++esc++ , ++tab++ : close search dialog * ++enter++ : follow selected result `global`{: #global } : This mode is active when _search is not focussed_ and when there's no other focussed element that is susceptible to keyboard input. The following keys are bound: * ++f++ , ++s++ , ++slash++ : open search dialog * ++p++ , ++comma++ : go to previous page * ++n++ , ++period++ : go to next page Let's say you want to bind some action to the ++x++ key. By using [additional JavaScript][33], you can subscribe to the `keyboard$` observable and attach your custom event listener: ``` js app.keyboard$.subscribe(function(key) { if (key.mode === "global" && key.type === "x") { /* Add custom keyboard handler here */ key.claim() } }) ``` The call to `#!js key.claim()` will essentially execute `#!js preventDefault()` on the underlying event, so the keypress will not propagate further and touch other event listeners.

While this is a reasonable default, as longer lines tend to be harder to read, it may be desirable to increase the overall width of the content area, or even make it stretch to the entire available space. This can easily be achieved with an [additional stylesheet][35] and a few lines of CSS: === "Increase width" ``` css .md-grid { max-width: 1440px; } ``` === "Stretch to fit" ``` css .md-grid { max-width: initial; } ``` [34]: https://github.com/squidfunk/mkdocs-material/blob/aeaa00a625abf952f355164de02c539b061e6127/src/assets/stylesheets/main/layout/_base.scss [35]: ../customization.md#additional-css
