echo CHtml::activeRadioButtonList($model,'name',array('1'=>'One','2'=>'Two')); 
//OR 
$type_list=CHtml::listData(Types::model()->findAll(),'id','type');
echo CHtml::activeRadioButtonList($model,'name',$type_list); 
?>

radioButtonList With Form

echo $form->radioButtonList($model,'name',array('1'=>'One','2'=>'Two')); 
//OR
$type_list=CHtml::listData(Types::model()->findAll(),'id','type');
echo $form->radioButtonList($model,'name',$type_list); 
?>

<?php 
//syntax:CHtml::radioButtonList(string name, default_select_by_array_keys,array_value());
<?php 
echo CHtml::radioButtonList('Typelist[name]',$selected_Array=array(),array('1'=>'One','2'=>'Two')); 
//OR
$type_list=CHtml::listData(Types::model()->findAll(),'id','type');
echo CHtml::radioButtonList('Typelist[name]',$selected_Array=array(),$type_list);
?>

    <label for="Typelist_name_0">One</label>br<
    <input value="2" id="Typelist_name_1" type="radio" name="Typelist[name][]">
    <label for="Typelist_name_1">Two</label>
</span>

radioButtonList Validation In Model

Add the validation to radioButtonList value in model.

<?php
.....
array('name', 'in','range'=>array(1,2)),
.....
?>

radioButtonList Value In Controller

We can retrieve selected value one by one using foreach() in controller and also we can use imploed() directly on this radiobutton name.

<?php
.........
$model->attributes=$_POST['Typelist'];
foreach($model->name as $radiobutton_id){
    echo $radiobutton_id;
}
.......
?>

Selected radioButton List Value From Database

Get the radiobutton list value from database for selected value array and all value

//selected value from db
$selected_type_list=CHtml::listData(Typelist::model()->findAll(),'id','type');
//all type list from db
$type_list=CHtml::listData(Types::model()->findAll(),'id','type');
echo CHtml::radioButtonList('typelist', $selected_type_list,$type_list);

radioButton List Style

Normally radioButton will display one by one. We can change this style using labelOptions. See below code

<?php
echo $form->radioButtonList($model,'type',
    array('1'=>'Admin','2'=>'User'),
    array(
        'template'=>'{input}{label}',
        'separator'=>'',
        'labelOptions'=>array(
            'style'=> '
                padding-left:13px;
                width: 60px;
                float: left;
            '),
            'style'=>'float:left;',
        )                              
    );
?>
  <div style="clear: both;"></div>
