Hi,
This should focus the input to the 1st field on initial page load and then on the 1st error after validation.
$form = $this->beginWidget('CActiveForm', array(
'htmlOptions' => array(
'enctype' => 'multipart/form-data',
),
'focus'=>($model->hasErrors()) ? '.error:first' : array($model, 'title'),
'enableClientValidation' => true,
));
Cheers,
Matt
