Question: I have table `types` and i want to build `selectbox` with all values from this table
In my controller i wrote this code

```
$allRegistrationTypes = RegistrationType::model()->findAll();
$this->render('index', array('allRegistrationTypes' => $allRegistrationTypes))

```

How build selectbox in view file ?

Answer: 
Well then its pretty simple all you need to do is first create List Data like

```
CHtml::ListData(allRegistrationTypes,'value you want to pass when item is selected','value you have to display');

```

for ex 

```
typeList = CHtml::ListData(allRegistrationTypes,'id','type');

```

now remember both ***id and type are fields in table*** 

now all you have to do is if you are using form then 

```
<?php echo $form->dropDownList($model, 'type_id', $typeList, array('empty'=>'Select a tyoe')); ?>

```

and if you need multiple you can pass `multiple => multiple` in the array as htmlOptions
Simplest Method to get "Select Box" in YII Framework:

```
<div class="row">
    <?php
        echo $form->labelEx($model,'county');
        $data = CHtml::listData(County::model()->findAll(), 'id', 'county');
        $htmlOptions =     array('size' => '1', 'prompt'=>'-- select county --', );
        echo $form->listBox($model,'county', $data, $htmlOptions);
        echo $form->error($model,'county');
    ?>
</div>

```

Good Luck..
