I solve this problem adding this line of code
if ($item->kategorija_id==3 || $item->kategorija_id==4 ) {
now code look like this and it works perfect.
<?php
$lastDefault = 0;
foreach ($ids as $itemId) {
$item = InfoPaket::model()->findByPk($itemId);
$kategorija = Kategorija::model()->findByPk($item->kategorija_id);
if ($item->kategorija_id==3 || $item->kategorija_id==4 ) {
echo '<li>';
echo '<img src="<?php echo Yii::app()->theme->baseUrl; ?>/images/infopaket/info_paket.png" />';
echo '<h2>';
echo strtoupper($kategorija->naziv);
echo '</h2>';
echo '<h1>';
echo "<a class='naslov' href='" . Yii::app()->getHomeUrl() . "?r=infoPaket/clanak&id=" . $item->id . "'>";
echo $item->naslov;
echo '</h1>';
echo '</a>';
echo '</li>';
}
}
?>

findByPk() accepts first argument as array too. So you can do
category::model()->findByPk(array('1', '2'));
Also, $item->category_id will return only single entry. If your item has multiple categories, than set up relations to categories and then get categories ID's with
CHtml::listData($item->categoriesRelationName, 'id', 'id');
can use function ($data){return $data->attribtues} too ---------^--- to get all attributes of model
