//OR
$type_list=CHtml::listData(Types::model()->findAll(),'id','type');
echo $form->checkBoxList($model,'name',$type_list);

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

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

checkBoxList Validation In Model

Add the validation to checkBoxList value in model.

<?php

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

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

Selected checkbox List Value From Database

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

checkbox List Style

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

<?php
echo $form->checkBoxList($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>
