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>
## Creating 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>
