mintlify[bot] d6960c72bf Improve SEO metadata across documentation pages (#5310)
* Improve SEO metadata: fix titles, descriptions, and remove redundant OpenAPI descriptions

- Remove description frontmatter from 19 API pages where the OpenAPI spec already supplies the description
- Fix 2 titles that exceeded 60 characters (content-templates, content-types)
- Improve 15 descriptions that were too short (<130 chars) or too long (>160 chars) to target 130-155 characters
- All descriptions are unique and include relevant search terms

title: "Code groups"
description: "Use the CodeGroup component to display multiple code examples in a tabbed interface and let readers compare implementations across languages."
keywords: ["code groups", "tabbed code", "multi-language examples", "CodeGroup"]
---
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>
