--- id: tabs title: Tabs description: Using tabs inside Docusaurus Markdown slug: /markdown-features/tabs --- ```mdx-code-block import BrowserWindow from '@site/src/components/BrowserWindow'; import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem'; import styles from './markdown-features-tabs-styles.module.css'; ``` Docusaurus provides the `` component that you can use in Markdown thanks to [MDX](./markdown-features-react.mdx): ```jsx import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem'; This is an apple 🍎 This is an orange 🍊 This is a banana 🍌 ``` ```mdx-code-block This is an apple 🍎 This is an orange 🍊 This is a banana 🍌 ``` --- It is also possible to provide `values` and `defaultValue` props to `Tabs`: ```jsx This is an apple 🍎 This is an orange 🍊 This is a banana 🍌 ``` ```mdx-code-block This is an apple 🍎 This is an orange 🍊 This is a banana 🍌
```
Tabs props take precedence over the TabItem props: ```jsx This is an apple 🍎 This is an orange 🍊 This is a banana 🍌 ``` ```mdx-code-block This is an apple 🍎 This is an orange 🍊 This is a banana 🍌
```
:::tip By default, all tabs are rendered eagerly during the build process, and search engines can index hidden tabs. It is possible to only render the default tab with ``. ::: ## Displaying a default tab {#displaying-a-default-tab} The first tab is displayed by default, and to override this behavior, you can specify a default tab by adding `default` to one of the tab items. You can also set the `defaultValue` prop of the `Tabs` component to the label value of your choice. For example, in the example above, either setting `default` for the `value="apple"` tab or setting `defaultValue="apple"` for the tabs forces the "Apple" tab to be open by default. Docusaurus will throw an error if a `defaultValue` is provided for the `Tabs` but it refers to a non-existing value. If you want none of the tabs to be shown by default, use `defaultValue={null}`. ## Syncing tab choices {#syncing-tab-choices} You may want choices of the same kind of tabs to sync with each other. For example, you might want to provide different instructions for users on Windows vs users on macOS, and you want to change all OS-specific instructions tabs in one click. To achieve that, you can give all related tabs the same `groupId` prop. Note that doing this will persist the choice in `localStorage` and all `` instances with the same `groupId` will update automatically when the value of one of them is changed. Note that group IDs are globally namespaced. ```jsx // highlight-next-line Use Ctrl + C to copy. Use Command + C to copy. // highlight-next-line Use Ctrl + V to paste. Use Command + V to paste. ``` ```mdx-code-block Use Ctrl + C to copy. Use Command + C to copy. Use Ctrl + V to paste. Use Command + V to paste.
``` For all tab groups that have the same `groupId`, the possible values do not need to be the same. If one tab group is chosen a value that does not exist in another tab group with the same `groupId`, the tab group with the missing value won't change its tab. You can see that from the following example. Try to select Linux, and the above tab groups don't change. ```jsx I am Windows. I am macOS. I am Linux. ``` ```mdx-code-block I am Windows. I am macOS. I am Linux. ``` --- Tab choices with different group IDs will not interfere with each other: ```jsx // highlight-next-line Windows in windows. macOS is macOS. // highlight-next-line Windows is windows. Unix is unix. ``` ```mdx-code-block Windows in windows. macOS is macOS. Windows is windows. Unix is unix. ``` ## Customizing tabs {#customizing-tabs} You might want to customize the appearance of a certain set of tabs. You can pass the string in `className` prop, and the specified CSS class will be added to the `Tabs` component: ```jsx // highlight-next-line This is an apple 🍎 This is an orange 🍊 This is a banana 🍌 ``` ```mdx-code-block This is an apple 🍎 This is an orange 🍊 This is a banana 🍌 ``` ### Customizing tab headings {#customizing-tab-headings} You can also customize each tab heading independently by using the `attributes` field. The extra props can be passed to the headings either through the `values` prop in `Tabs`, or props of each `TabItem`β€”in the same way as you declare `label`. ```jsx title="some-doc.mdx" import styles from './styles.module.css'; This is an apple 🍎 This is an orange 🍊 This is a banana 🍌 ``` ```css title="styles.module.css" .red { color: red; } .red[aria-selected='true'] { border-bottom-color: red; } .orange { color: orange; } .orange[aria-selected='true'] { border-bottom-color: orange; } .yellow { color: yellow; } .yellow[aria-selected='true'] { border-bottom-color: yellow; } ``` ```mdx-code-block This is an apple 🍎 This is an orange 🍊 This is a banana 🍌 ``` :::tip `className` would be merged with other default class names. You may also use a custom `data-value` field (`{'data-value': 'apple'}`) paired with CSS attribute selectors: ```css title="styles.module.css" li[role='tab'][data-value='apple'] { color: red; } ``` :::
