# Django Admin preset resolvers

`AdminAlpineMixin` loads `admin.js`, which registers the following resolvers automatically. Each resolver maps a prefix to a target container in the Django Admin DOM.

### Show/hide a form row

```python
extra_field = forms.CharField(
    widget=forms.TextInput(attrs={

        "x-form-row-show": "showExtra",
    })

```python
class MyInlineForm(AdminAlpineMixin, forms.ModelForm):

            "x-inline-container-show": "__row_prefix__active",
