# Deprecated Inner Blocks Control

Inner Blocks control is **deprecated** since v3.4.0. You need to migrate to the **<InnerBlocks />** component as this control will be removed in future updates.

## Migration Guide

Follow these steps to migrate from the deprecated control to the <InnerBlocks /> component:

1. Add the <InnerBlocks /> component to your block output code (both Frontend and Editor):
   

2. Remove the Inner Blocks control:
   

3. Learn more about <InnerBlocks /> component features in our [documentation](https://www.lazyblocks.com/docs/blocks-code/inner-blocks/).

The new <InnerBlocks /> component provides better performance and more features than the deprecated control.

## Deprecated Control Documentation

This documentation is for the deprecated control. We strongly recommend migrating to the new <InnerBlocks /> component.

Inner Blocks control creates a nested blocks area in your block. You can only use one Inner Blocks control per block.

### Usage

```php title="PHP" /$attributes['control_name']/
<div>
  <?php echo $attributes['control_name']; ?>
</div>
```

```hbs title="Handlebars" /{{{control_name}}}/
<div>
  {{{control_name}}}
</div>
```

When using Handlebars, use triple curly brackets to output HTML: `{{{` and `}}}`

Inner Blocks cannot be used as Meta fields.
