Use the `CodeGroup` component to display multiple code blocks in a tabbed interface, allowing users to compare implementations across different programming languages or see alternative approaches for the same task.

<CodeGroup>

```javascript helloWorld.js
console.log("Hello World");
```

```python hello_world.py
print('Hello World!')
```

```java HelloWorld.java
class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
```

</CodeGroup>

Code groups inherit global styling from your `docs.json` file. Customize your theme using `styling.codeblocks`. See [Settings](/organize/settings-appearance#styling) for configuration options.

Code groups automatically synchronize with other code groups and [tabs](/components/tabs) on the same page when their labels match. When you select a language in one code group, all tabs and code groups with matching labels update to show the same language.

## Create code groups

To create a code group, wrap multiple code blocks with `<CodeGroup>` tags. Each code block must include a title, which becomes the tab label.

````mdx
<CodeGroup>

```javascript helloWorld.js
console.log("Hello World");
```

```python hello_world.py
print('Hello World!')
```

```java HelloWorld.java
class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
```

</CodeGroup>
````

## Language dropdown

You can replace the tabs in a code group with a dropdown menu to toggle between languages using the `dropdown` prop.

<CodeGroup dropdown>

```javascript helloWorld.js
console.log("Hello World");
```

```python hello_world.py
print('Hello World!')
```

```java HelloWorld.java
class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
```

</CodeGroup>

````mdx highlight=1
<CodeGroup dropdown>

```javascript helloWorld.js
console.log("Hello World");
```

```python hello_world.py
print('Hello World!')
```

```java HelloWorld.java
class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
```
</CodeGroup>
