 1 | Yii2 Nested Sets Editor
 2 | ===
 3 | 
 4 | This behavior soon will be **DEPRECATED**.  
 5 | See the new version [**Yii2 Tree Manager**](https://github.com/voskobovich/yii2-tree-manager).
 6 | 
 7 | ## About
 8 | Editor nested set using jquery.nestable plugin.
 9 | 
10 | Реализует полный набор CRUD операций для узлов дерева.
11 | 
12 | Внимание!
13 | ---
14 | Есть улучшеная версия пакета для управление деревом - [yii2-tree-manager](https://github.com/voskobovich/yii2-tree-manager).
15 | 
16 | Installation
17 | -------------
18 | 
19 | The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
20 | 
21 | Either run
22 | 
23 | ```
24 | php composer.phar require --prefer-dist voskobovich/yii2-nested-sets-editor "~1.0.0"
25 | ```
26 | 
27 | or add
28 | 
29 | ```
30 | "voskobovich/yii2-nested-sets-editor": "~1.0.0"
31 | ```
32 | 
33 | to the require section of your `composer.json` file.
34 | 
35 | 
36 | Внимание!
37 | -----
38 | В расширении наследуется и расширяется behavior [Nested Sets Behavior for Yii 2](https://github.com/creocoder/yii2-nested-sets).  
39 | Всю информацию по настройке поведения можно взять на [странице](https://github.com/creocoder/yii2-nested-sets).
40 | 
41 | Но для работы виджета нужно использовать реализацию поведения из этого пакета!
42 | 
43 | 
44 | Usage
45 | -----
46 | 1. Подключите behavior из этого пакета к своей модели и сконфигурируйте как сказано в [документации](https://github.com/creocoder/yii2-nested-sets).
47 | ```
48 | public function behaviors()
49 | {
50 |     return [
51 |         'nestedSetsBehavior' => 'voskobovich\nestedsets\behaviors\NestedSetsBehavior',
52 |     ];
53 | }
54 | ```  
55 | 2. Подключите в контроллер дополнительные actions
56 | ```
57 | public function actions()
58 | {
59 |     return [
60 |         'moveNode' => [
61 |             'class' => 'voskobovich\nestedsets\actions\MoveNodeAction',
62 |             'modelClass' => 'models\ModelName',
63 |         ],
64 |         'deleteNode' => [
65 |             'class' => 'voskobovich\nestedsets\actions\DeleteNodeAction',
66 |             'modelClass' => 'models\ModelName',
67 |         ],
68 |         'updateNode' => [
69 |             'class' => 'voskobovich\nestedsets\actions\UpdateNodeAction',
70 |             'modelClass' => 'models\ModelName',
71 |         ],
72 |         'createNode' => [
73 |             'class' => 'voskobovich\nestedsets\actions\CreateNodeAction',
74 |             'modelClass' => 'models\ModelName',
75 |         ],
76 |     ];
77 | }
78 | ```  
79 | 3. Выведите виджет в удобном месте
80 | ```
81 | <?= \voskobovich\nestedsets\widgets\nestable\Nestable::widget([
82 |     'modelClass' => 'models\ModelName',
83 | ]) ?>
84 | ```
