PHP Development Framework Yii Framework Tutorial (a) UI component TreeView sample

CTreeView is used to display data with hierarchies, using the TreeView to set up the Data property. Data is an array with the following structure:

Ext:string, the text of the tree node.

Expanded:boolean, optionally, indicates whether the node is expanded.

Id:string, optional, the node ID.

Haschildren:boolean, optionally, the default is False, and when True indicates that the node contains child nodes.

Children:array, optional, sub-node array.

Htmloptions:array, HTML options.

So far we haven't introduced the read database, so this example uses the hard code data as follows:
