Yii2 gridview row options

In Yii2 GridView, if you want to highlight or focus on certain row, you can use rowOptions attribute in your gridview.

Below are the example code.

<?=
GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
      'rowOptions' => function ($model, $index, $widget, $grid) {

                            if ($model->is_read == 1) {
                                return ['class' => 'read'];
                            } else {
                                return [];
                            }
                         },
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
         ['class' => 'yii\grid\ActionColumn']
    ],
]);
?>

Yii2 Modify GridView Filters

In Yii2  the filter input fields are automatically generated by the widget component, but we can modify to our needs by using the "filterPosition" property in Gridview widget.


To remove entire filters on Gridview,

'filterPosition'=>' ',

To show the fiters  on  top of each column's header cell,

  'filterPosition'=>'header',

To show the fiters  right below of each column's header cell,

 'filterPosition'=>'body',


To show the fiters  below each column's footer cell,

 'filterPosition'=>'footer',

By default Yii filters the table in cgridview, when a user entering data on search textfield and press Enter key or clicking oustside the grid.
I had a strange situation, i want to apply filter on keyup in cgridview for all pages,

    $(function() {
        $('body').on('keyup', '.filters > td > input', function() {
           
            var focusedId = $(document.activeElement).attr('id');
            var grid_id = $('#' + focusedId + '.form').closest("div").attr('id');
           
            $('#' + grid_id).yiiGridView('update', {
                data: $(this).serialize(),
                complete: function(jqXHR, status) {
                   
                    if (status == 'success') {
                        var tmpStr = $('#' + focusedId + '.form').val();
                        $('#' + focusedId + '.form').focus();
                        $('#' + focusedId + '.form').val('');
                        $('#' + focusedId + '.form').val(tmpStr);
                    }
