Automatically line break in Yii - php

Question

If not including PHP, there is no error.
If include Yii CMenu, automatically added white space before CMenu
Example:
<div id="umenu">
<?php $this->widget('zii.widgets.CMenu', array(
'encodeLabel' => false,
'items' => array(
array('label' => ' ', 'url' => '/', 'itemOptions' => array('class' => 'umenu1')),
array('label' => 'RÓLUNK', 'url' => StaticpageModule::getUrl(1), 'itemOptions' => array('class' => 'umenu2')),
array('label' => 'TERMELÉS', 'url' => StaticpageModule::getUrl(2), 'itemOptions' => array('class' => 'umenu3')),
array('label' => 'A KÁVÉ', 'url' => StaticpageModule::getUrl(3), 'itemOptions' => array('class' => 'umenu4')),
array('label' => 'EGYÜTTMŰKÖDÉS', 'url' => StaticpageModule::getUrl(5), 'itemOptions' => array('class' => 'umenu5')),
array('label' => 'KAPCSOLAT', 'url' => StaticpageModule::getUrl(4), 'itemOptions' => array('class' => 'umenu6')),
),
)); ?>
</div>
Output:

Answer 1

Well, as PeterM said in its comment, you have whitespaces after opening div#menu...
And about double quotes you see in chrome dev tool :
when a string literal is not on the same line with its surrounding tag
then the string literal is displayed on a new line with quotes around
the string literal to make it visible where the string starts and
ends.
What is the purpose of the quotes around some dollar values on certain retail sites?

Answer 2

Change
<div id="umenu">
<?php $this->widget('zii.widgets.CMenu', array(
To
<div id="umenu"><?php $this->widget('zii.widgets.CMenu', array(

Answer 3

From the reference documentation for the widget constructor, it looks like you might need to pass false as the $captureOutput flag to tell it not to push any output to the page.
Try:
<?php $this->widget('zii.widgets.CMenu', array(
'encodeLabel' => false,
'items' => array(
array('label' => ' ', 'url' => '/', 'itemOptions' => array('class' => 'umenu1')),
array('label' => 'RÓLUNK', 'url' => StaticpageModule::getUrl(1), 'itemOptions' => array('class' => 'umenu2')),
array('label' => 'TERMELÉS', 'url' => StaticpageModule::getUrl(2), 'itemOptions' => array('class' => 'umenu3')),
array('label' => 'A KÁVÉ', 'url' => StaticpageModule::getUrl(3), 'itemOptions' => array('class' => 'umenu4')),
array('label' => 'EGYÜTTMŰKÖDÉS', 'url' => StaticpageModule::getUrl(5), 'itemOptions' => array('class' => 'umenu5')),
array('label' => 'KAPCSOLAT', 'url' => StaticpageModule::getUrl(4), 'itemOptions' => array('class' => 'umenu6')),
),
false
));
