* @column string field
* @value the corresponding value of the Mix field, not specified returns the field array

value ' => function ($model) {return
Article::d ropdown (' Is_hot ', $model- >is_hot);
},
' filter ' => Article::d ropdown (' Is_hot '),
],
[
' attribute ' => ' Is_ Delete ',
' value ' => function ($model) {return
Article::d ropdown (' Is_delete ', $model->is_delete);
} ,
' filter ' => Article::d ropdown (' Is_delete '),
],
