Answer 1

visit a complete tutorial about this question in :

http://www.yiiframework.com/wiki/851/yii2-gridview-sorting-and-searching-with-a-junction-table-column-many-to-many-relationship/

according to this tutorial you should : 1. set your related table attribute as public in search model like this :

public $groupname;

2 . include attribute in the rules :

    public function rules() {
        return [
            [['id', 'gender', 'status', 'sentstatus'], 'integer'],
            [['groupname', 'addeddate', 'updateddate'], 'safe'],
        ];
    }

3. change default query to following code in function search() in search model :

   public function search($params) {
   $query = Contacts::find()->innerJoinWith('groups', true);
   
   

4. and in andfilterwhere add wanted attribute . like this :

   $query->andFilterWhere(['like', 'firstname', $this->firstname])
                  ... 
                   ->andFilterWhere(['like', 'groupname', $this->groupname]);
   

in your view class and in Gridview your wanted column should like this :

'columns' => [
                ...
            [
                'attribute' => 'tags',
                'format' => 'raw',
                'value' => function ($data) {
                    $groups= '';
                    foreach ($data->groups as $group) {
                        $groups .= '' .
                        $group->group_name . ' | ';
                    }
                    return $groups;
         },
        'filter' => ArrayHelper::map(group::find()->asArray()->all(), 'group_name','group_name'),
                ],

and if table relation is hasOne() you should read this tutorial :
