Hey party people - Quick question:  
If I override a component: Is there a way to really extend a method or properties instead of overwriting the whole property or method to keep the core data?

For example, i want to override component XY which has some computed properties:

```
computed: {
        fooBar() {
            return [
                { value: 'foo' },
                { value: 'foo' }
            ];
        },
...

```

Now instead of overriding the whole property fooBar, I just want to extend it / push the new value to it to keep the core values and not override them.  
I would do it with something like

```
corevalues.push('...');

```

But I am wondering how would I get the core values from the parent component? 🙂

If I am looking at the vue docs, this would be done with mixins: [https://vuejs.org/v2/guide/mixins.html#Option-Merging](https://vuejs.org/v2/guide/mixins.html#Option-Merging)  
But the core component within Shopware doesn’t use those mixins for the values as far as i see. So is there a “Shopware way” to merge those values within administration components/modules?

There is at least a property merger out there very useful. Unfortunatley it is missing option merge, but you may want to extend it yourself. Workaround could be to put the „to merge options“ in a fake group and then perform the group merge, before that - cleaning spaces, or other inconsistent data so it will merge /override.
