and render index. can use $comment in index how can pass _item? tried this:

 <?php                 echo listview::widget( [                     'dataprovider' => $dataprovider,                     'itemview' => '_item',                     'summary'=>'',                      'comment' => $comment                 ]); ?> 

and tried in _item:

<?= $model->getstatus($model->cnnewscontenttype_id); ?> <br>         <?php $form = activeform::begin(); ?>     <?= $form->field($comment, 'text')->textinput(['maxlength' => true])->label('treść') ?>     <?php activeform::end(); ?> 

but have error:

unknown property – yii\base\unknownpropertyexception

setting unknown property: yii\widgets\listview::comment

in _item can use $model. possible pass $comment _item view? pls me

you should use viewparams :

additional parameters passed $itemview when being rendered. property used when $itemview string representing view name.

e.g. :

<?= listview::widget( [     'dataprovider' => $dataprovider,     'itemview' => '_item',     'viewparams' => ['comment' => $comment],     'summary'=>'',  ]); ?>
