// default with label echo Progress::widget([ 'percent' => 60, 'label' => 'test', ]); // styled echo Progress::widget([ 'percent' => 65, 'barOptions' => ['class' => 'progress-bar-danger'] ]); // striped echo Progress::widget([ 'percent' => 70, 'barOptions' => ['class' => 'progress-bar-warning'], 'options' => ['class' => 'progress-striped'] ]); // striped animated echo Progress::widget([ 'percent' => 70, 'barOptions' => ['class' => 'progress-bar-success'], 'options' => ['class' => 'active progress-striped'] ]); // stacked bars echo Progress::widget([ 'bars' => [ ['percent' => 30, 'options' => ['class' => 'progress-bar-danger']], ['percent' => 30, 'label' => 'test', 'options' => ['class' => 'progress-bar-success']], ['percent' => 35, 'options' => ['class' => 'progress-bar-warning']], ] ]);
