CTreeView用來顯示具有層次結構的數據，使用TreeView 通過設置Data屬性。Data為具有下面結構的數組：
ext: string, 樹節點的文本.
expanded: boolean,可選，表示該節點是否展開.
id: string, 可選，該節點ID.
hasChildren: boolean, 可選，缺省為False,當為True表示該節點含有子節點.
children: array,可選，子節點數組。.
htmlOptions: array, HTML選項。
到目前為止我們還沒有介紹讀取數據庫，因此本例使用Hard Code的數據如下：
array(
'text' => '<a id="27" href="#">World:4</a>' ,
'id' => '27' ,
'hasChildren' => true,
'children' =>
array
(
