Provide an ability to easy manage relation data by creating tabs for the relation dependency instead of clicking into other menu entries.

Example from the Docs:

Crud Relation Tabs

Sometimes its usefull and common to directly manage relational data inside the current ngrest crud. Therefore we have created something called ngRestRelations(). Inside this method you can define relations which are also based on the NgRest concept.

public function ngRestRelation()
{
    return [
        ['label' => 'The Label', 'apiEndpoint' => \path\to\ngRest\Model::ngRestApiEndpoint(), 'dataProvider' => $this->getSales()],
    ];
}

The above example will use the getSales() method of the current model where you are implementing this relation. The getSales() must return an {{yii\db\QueryInterface}} Object, for example you can use $this->hasMany(Model, ['key' => 'rel']) or new \yii\db\Query().

Tip: If you generate an NgRest model for a relation which is not used in any other situations you can hide those items from the menu, but not from the permission system. To hide en element add the hiddenInMenu option in the getMenu() method of the module as following: itemApi('name', 'route', 'icon', 'api', ['hiddenInMenu' => true]).
