import Tabs from '@theme/Tabs';

import TabItem from '@theme/TabItem';

To show tabbed content within Markdown files, you can fall back on MDX. Docusaurus provides `<Tabs>` components out-of-the-box.

```jsx
import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';

<Tabs
  defaultValue="apple"
  values={[
    {label: 'Apple', value: 'apple'},
    {label: 'Orange', value: 'orange'},
    {label: 'Banana', value: 'banana'},
  ]}>
  <TabItem value="apple">This is an apple 🍎</TabItem>
  <TabItem value="orange">This is an orange 🍊</TabItem>
  <TabItem value="banana">This is a banana 🍌</TabItem>
</Tabs>;
```

And you will get the following:

```mdx-code-block
<Tabs
  defaultValue="apple"
  values={[
    {label: 'Apple', value: 'apple'},
    {label: 'Orange', value: 'orange'},
    {label: 'Banana', value: 'banana'},
  ]}>
  <TabItem value="apple">This is an apple 🍎</TabItem>
  <TabItem value="orange">This is an orange 🍊</TabItem>
  <TabItem value="banana">This is a banana 🍌</TabItem>
</Tabs>
```

:::info

By default, tabs are rendered eagerly, but it is possible to load them lazily by passing the `lazy` prop to the `Tabs` component.

:::

## Displaying a default tab

Set the `defaultValue` prop in the `Tabs` component to the label value of your choice to show the matching tab by default.

For example, in the example above, `defaultValue="apple"` forces the `Apple` tab to be open by default.

If the `defaultValue` prop is not provided or refers to an non-existing value, only the tab headings appear until the user clicks on a tab.

## 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 changing 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 `<Tab>` instances with the same `groupId` will update automatically when the value of one of them is changed. Note that `groupID` are globally-namespaced.

```jsx {2,14}
<Tabs
  groupId="operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'macOS', value: 'mac'},
  ]
}>
<TabItem value="win">Use Ctrl + C to copy.</TabItem>
<TabItem value="mac">Use Command + C to copy.</TabItem>
</Tabs>

<Tabs
  groupId="operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'macOS', value: 'mac'},
  ]
}>
<TabItem value="win">Use Ctrl + V to paste.</TabItem>
<TabItem value="mac">Use Command + V to paste.</TabItem>
</Tabs>
```

```mdx-code-block
<Tabs
  groupId="operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'macOS', value: 'mac'},
  ]}>
  <TabItem value="win">Use Ctrl + C to copy.</TabItem>
  <TabItem value="mac">Use Command + C to copy.</TabItem>
</Tabs>

<Tabs
  groupId="operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'macOS', value: 'mac'},
  ]}>
  <TabItem value="win">Use Ctrl + V to paste.</TabItem>
  <TabItem value="mac">Use Command + V to paste.</TabItem>
</Tabs>
```

For all tab groups that have the same `groupId`, the possible values do not need to be the same. If one tab group with chooses an 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 doesn't change.

```jsx
<Tabs
  groupId="operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'macOS', value: 'mac'},
    {label: 'Linux', value: 'linux'},
  ]}>
  <TabItem value="win">I am Windows.</TabItem>
  <TabItem value="mac">I am macOS.</TabItem>
  <TabItem value="linux">I am Linux.</TabItem>
</Tabs>
```

```mdx-code-block
<Tabs
  groupId="operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'macOS', value: 'mac'},
    {label: 'Linux', value: 'linux'},
  ]}>
  <TabItem value="win">I am Windows.</TabItem>
  <TabItem value="mac">I am macOS.</TabItem>
  <TabItem value="linux">I am Linux.</TabItem>
</Tabs>
```

Tab choices with different `groupId`s will not interfere with each other:

```jsx {2,14}
<Tabs
  groupId="operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'macOS', value: 'mac'},
  ]
}>
<TabItem value="win">Windows in windows.</TabItem>
<TabItem value="mac">macOS is macOS.</TabItem>
</Tabs>

<Tabs
  groupId="non-mac-operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'Unix', value: 'unix'},
  ]
}>
<TabItem value="win">Windows is windows.</TabItem>
<TabItem value="unix">Unix is unix.</TabItem>
</Tabs>
```

```mdx-code-block
<Tabs
  groupId="operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'macOS', value: 'mac'},
  ]}>
  <TabItem value="win">Windows in windows.</TabItem>
  <TabItem value="mac">macOS is macOS.</TabItem>
</Tabs>

<Tabs
  groupId="non-mac-operating-systems"
  defaultValue="win"
  values={[
    {label: 'Windows', value: 'win'},
    {label: 'Unix', value: 'unix'},
  ]}>
  <TabItem value="win">Windows is windows.</TabItem>
  <TabItem value="unix">Unix is unix.</TabItem>
</Tabs>
```

## Customizing tabs {#customizing-tabs}

You might want to customize the appearance of certain set of tabs. To do that you can pass the string in `className` prop and the specified CSS class will be added to the `Tabs` component:

```jsx {5}
import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';

<Tabs
  className="unique-tabs"
  defaultValue="apple"
  values={[
    {label: 'Apple', value: 'apple'},
    {label: 'Orange', value: 'orange'},
    {label: 'Banana', value: 'banana'},
  ]}>
  <TabItem value="apple">This is an apple 🍎</TabItem>
  <TabItem value="orange">This is an orange 🍊</TabItem>
  <TabItem value="banana">This is a banana 🍌</TabItem>
</Tabs>;
```

```mdx-code-block
<Tabs
  className="unique-tabs"
  defaultValue="apple"
  values={[
    {label: 'Apple', value: 'apple'},
    {label: 'Orange', value: 'orange'},
    {label: 'Banana', value: 'banana'},
  ]}>
  <TabItem value="apple">This is an apple 🍎</TabItem>
  <TabItem value="orange">This is an orange 🍊</TabItem>
  <TabItem value="banana">This is a banana 🍌</TabItem>
</Tabs>
```
