How to create a child theme in OpenCart 4?

Question

I want to modify the default theme but don't want to lose changes when updating.

How to properly create a child theme in OC4?

Does OpenCart 4 support this concept at all?

Unfortunately, **OC4 doesn't have native support** for child themes like WordPress.

**Alternative solutions:**

1. **TWIG extends**
```twig
{% extends 'default/template/common/header.twig' %}
{% block content %}
    {# Your changes #}
{% endblock %}
```

2. **Theme override via module**
- Create module with custom templates
- Register via events

3. **Symbolic links**
```bash
ln -s /themes/custom/modified.twig /themes/default/original.twig
```

Most reliable option - separate module with overrides!
