` in the view, you can define such converters:
```typescript
editor.conversion.for( 'editingDowncast' )
.elementToElement( {
model: 'nested',
view: ( modelItem, { writer } ) => {
const div = writer.createEditableElement( 'div', { class: 'nested' } );
return toWidgetEditable( nested, writer, { label: 'label for editable' } );
}
} );
editor.conversion.for( 'dataDowncast' )
.elementToElement( {
model: 'nested',
view: ( modelItem, { writer } ) => {
return writer.createContainerElement( 'div', { class: 'nested' } );
}
} );
```

#### Parameters
* `editable: ViewEditableElement`
* `writer: ViewDowncastWriter`
* `options: object`
Additional options.
Properties
* `options.label?: string`
Editable's label used by assistive technologies (e.g. screen readers).
* `options.withAriaRole?: boolean`
Whether to add the role="textbox" attribute on the editable. Defaults to `true`.
Defaults to `{}`
#### Returns
* `ViewEditableElement`
Returns the same element that was provided in the `editable` parameter
### `viewToModelPositionOutsideModelElement( model, viewElementMatcher ) → GetCallback`
A util to be used in order to map view positions to correct model positions when implementing a widget which renders non-empty view element for an empty model element.
For example:
```
// Model:
// View:
name
```
In such case, view positions inside `` cannot be correctly mapped to the model (because the model element is empty). To handle mapping positions inside `` to the model use this util as follows:
```typescript
editor.editing.mapper.on(
'viewToModelPosition',
viewToModelPositionOutsideModelElement( model, viewElement => viewElement.hasClass( 'placeholder' ) )
);
```
The callback will try to map the view offset of selection to an expected model position.
1. When the position is at the end (or in the middle) of the inline widget:
```
// View:
foo name| bar
// Model:
foo | bar
```
2. When the position is at the beginning of the inline widget:
```
// View:
foo |name bar
// Model:
foo | bar
```
[See source](https://github.com/ckeditor/ckeditor5/blob/master/packages/ckeditor5-widget/src/utils.ts#L422)
#### Parameters
* `model: Model`
Model instance on which the callback operates.
* `viewElementMatcher: ( element: ViewElement ) => boolean`
Function that is passed a view element and should return `true` if the custom mapping should be applied to the given view element.
#### Returns
* `GetCallback`
