<?php echo $this->widget('CAutoComplete',
array(
             'name'=>'user_name', //name of the html field that will be generated 'url'=>array('controller/action'),name'=>'user_name', 
 
 //replace controller/action with real ids              'url'=>array('controller/action'), 
 
 'max'=>10, //specifies the max number of items to display              'minChars'=>2,  
 
 //specifies the number of chars that must be entered
 
 //before autocomplete initiates a lookup              'minChars'=>2, 
 
 'delay'=>500, //number of milliseconds before lookup occurs 'matchCase'=>false, //match case when performing a lookup?              'htmlOptions'=>array('size'=>'40'),  
 
 //any additional html attributes that go inside of
 
 //the input field can be defined here              'htmlOptions'=>array('size'=>'40'), 
 
 
 'methodChain'=>".result(function(event,item){\$(\"#user_id\").val(item[1]);})",
));
?>
<?php echo CHtml::hiddenField('user_id'); ?>
```
Take note of the `methodChain` attribute being used. MethodChain essentially appends (or chains) a javascript method to the end of the AutoComplete javascript code that will be generated. This particular method is the `result` method, which fires when an autocomplete item is selected. The code inside of the result function basically references the hidden field that was defined and assigns the 2nd part (part after the pipe) of the selected autocomplete data to that field.
