It changes comma separated widget to list based in admin panel.

## Quickstart

Install Django better admin ArrayField:

    pip install django-better-admin-arrayfield

Add it to your \`INSTALLED\_APPS\`:

```python
INSTALLED_APPS = (
    ...
    'django_better_admin_arrayfield',
    ...
)
```


## Usage

`django_better_admin_arrayfield.models.fields.ArrayField` is a drop-in replacement for standard Django `ArrayField`.

Import it like below and use it in your model class definition.
```python
from django_better_admin_arrayfield.models.fields import ArrayField
```

Import DynamicArrayMixin like below
```python
from django_better_admin_arrayfield.admin.mixins import DynamicArrayMixin
```

In your admin class add `DynamicArrayMixin`:
    ...
```python
class MyModelAdmin(admin.ModelAdmin, DynamicArrayMixin):
```

That's it.


### Custom subwidget

By default the subwidget (the one used for each item in the array) will be TextInput. If you want something else, you can use your own specifying it in the `formfield_overrides` of your Admin model:
```python
class MyWidget(DynamicArrayWidget):
    def __init__(self, *args, **kwargs):
        kwargs['subwidget_form'] = MyForm
        super().__init__(*args, **kwargs)

class MyModelAdmin(models.ModelAdmin, DynamicArrayMixin):
    ...
    formfield_overrides = {
        DynamicArrayField: {'widget': MyWidget},
    }
```

If you wanted to have Textarea as the subwidget, you can simply use the included drop-in widget replacement:
```python
from django_better_admin_arrayfield.forms.widgets import DynamicArrayTextareaWidget

class MyModelAdmin(models.ModelAdmin, DynamicArrayMixin):
    ...
    formfield_overrides = {
        DynamicArrayField: {'widget': DynamicArrayTextareaWidget},
    }
```
