The component renders draggable items as a tree without the possibility of collapsing. Data-Source must be `Object Array` in the form: `{ id: String, children: [ ], YOUR PROPERTIES }, { ... }`


__Configuration__:

- `empty {String}` an empty text (default: `null`)
- `onchange {String}` optional, a link to the `function(arr)` - captures items when resorted

__Template__:

```html
{{ level }} contains a level (number)
{{ value }} contains an item (object)
```

Try to understand the functionality from the example.

__Good to know__:

- `component.items {Object}` contains all references of all items in the form `items[item.id] = item`
- `component.parents {Object}` contains all references of all parents in the form `parents[item.id] = parent`

Use it with `<ui-component name="children">`. When the component is not loaded yet, jComponent downloads it on first use from the address in `DEF.fallback` (the Componentator CDN by default). Author: Peter Širka. Source: the Componentator components repository, MIT license.
