/**
* ActiveField represents a form input field within an [[ActiveForm]] and extends the [[YiiActiveField]] component
* to handle various bootstrap functionality like form types, input groups/addons, toggle buttons, feedback icons, and
* other enhancements
*
* Usage example with addons:
*
* ```php
* // $form is your active form instance
* echo $form->field($model, 'email', ['addon' => ['type'=>'prepend', 'content'=>'@']]);
* echo $form->field($model, 'amount_paid', ['addon' => ['type'=>'append', 'content'=>'.00']]);
* echo $form->field($model, 'phone', [
* 'addon' => [
* 'type'=>'prepend',
* 'content'=>'<i class="fas fa-mobile-alt"></i>'
* ]
* ]);
* ```
*
* Usage example with horizontal form and advanced field layout CSS configuration:
*
* ```php
* echo $form->field($model, 'email', ['labelSpan' => 2, 'deviceSize' => ActiveForm::SIZE_SMALL]]);
* echo $form->field($model, 'amount_paid', ['horizontalCssClasses' => ['wrapper' => 'hidden-xs']]);
* echo $form->field($model, 'phone', [
* 'horizontalCssClasses' => ['label' => 'col-md-2 col-sm-3 col-xs-12 myRedClass']
* ]);
* echo $form->field($model, 'special', [
* 'template' => '{beginLabel}For: {labelTitle}{endLabel}\n{beginWrapper}\n{input}\n{hint}\n{error}\n{endWrapper}'
* ]);
* ```
