Sortable modification of standard Yii2 GridView widget.

The preferred way to install this extension is through composer.

• Either run

php composer.phar require --prefer-dist "himiklab/yii2-sortable-grid-view-widget" "*"

or add

"himiklab/yii2-sortable-grid-view-widget" : "*"

to the require section of your application's composer.json file.

• Add to your database new unsigned int attribute, such sortOrder.

• Add new behavior in the AR model, for example:

use himiklab\sortablegrid\SortableGridBehavior;

public function behaviors()
{
    return [
        'sort' => [
            'class' => SortableGridBehavior::className(),
            'sortableAttribute' => 'sortOrder',
            'scopeAttribute' => 'parentId'            
        ],
    ];
}

• Add action in the controller, for example:

use himiklab\sortablegrid\SortableGridAction;

public function actions()
{
    return [
        'sort' => [
            'class' => SortableGridAction::className(),
            'modelName' => Model::className(),
        ],
    ];
}

• Use SortableGridView as standard GridView with sortableAction option. You can also subscribe to the JS event 'sortableSuccess' generated widget after a successful sorting.

Sometimes a table contains sort orders for multiple scopes. For example, a list of filters linked to a specific category. The scopeAttribute can be used to segment the sequence list. New items automatically get the next sort order in the segment.
