/** |
|
* A Bootstrap 3 enhanced version of [[\yii\widgets\ActiveForm]]. |
|
* |
|
* This class mainly adds the [[layout]] property to choose a Bootstrap 3 form layout. |
|
* So for example to render a horizontal form you would: |
|
* |
|
* ```php |
|
* use yii\bootstrap\ActiveForm; |
|
* |
|
* $form = ActiveForm::begin(['layout' => 'horizontal']) |
|
* ``` |
|
* |
|
* This will set default values for the [[ActiveField]] |
|
* to render horizontal form fields. In particular the [[ActiveField::template|template]] |
|
* is set to `{label} {beginWrapper} {input} {error} {endWrapper} {hint}` and the |
|
* [[ActiveField::horizontalCssClasses|horizontalCssClasses]] are set to: |
|
* |
|
* ```php |
|
* [ |
|
* 'offset' => 'col-sm-offset-3', |
|
* 'label' => 'col-sm-3', |
|
* 'wrapper' => 'col-sm-6', |
|
* 'error' => '', |
|
* 'hint' => 'col-sm-3', |
|
* ] |
|
* ``` |
|
* |
|
* To get a different column layout in horizontal mode you can modify those options |
|
* through [[fieldConfig]]: |
|
* |
|
* ```php |
|
* $form = ActiveForm::begin([ |
|
* 'layout' => 'horizontal', |
|
* 'fieldConfig' => [ |
|
* 'template' => "{label}\n{beginWrapper}\n{input}\n{hint}\n{error}\n{endWrapper}", |
|
* 'horizontalCssClasses' => [ |
|
* 'label' => 'col-sm-4', |
|
* 'offset' => 'col-sm-offset-4', |
|
* 'wrapper' => 'col-sm-8', |
|
* 'error' => '', |
|
* 'hint' => '', |
|
* ], |
|
* ], |
|
* ]); |
|
* ``` |
|
* |
|
* @see ActiveField for details on the [[fieldConfig]] options |
|
* @see http://getbootstrap.com/css/#forms |
