## Theme inheritance

While you can't set two themes active at once, you can make use of multiple inheritance. Eg.:

```json
{
    "name": "vendor/child-theme",
    "extra": {
        "sylius-theme": {
            "title": "Child theme",
            "parents": ["vendor/first-parent-theme", "vendor/second-parent-theme"]
        }
    }
}
```

```json
{
    "name": "vendor/first-parent-theme",
    "extra": {
        "sylius-theme": {
            "title": "First parent theme",
            "parents": ["vendor/grand-parent-theme"]
        }
    }
}
```

```json
{
    "name": "vendor/grand-parent-theme",
    "extra": {
        "sylius-theme": {
            "title": "Grandparent theme"
        }
    }
}
```

```json
{
    "name": "vendor/second-parent-theme",
    "extra": {
        "sylius-theme": {
            "title": "Second parent theme",
        }
    }
}
```

Configuration showed below will result in given order:

- Child theme
- First parent theme
- Grandparent theme
- Second parent theme

Grandparent theme gets overrided by first parent theme. First parent theme and second parent theme get overrided by child theme.
