For example, the following tree control has all its nodes expanded:

<mm:treenode value="node1" state="expanded"></mm:treenode>

<mm:treenode value="node3" state="expanded"></mm:treenode>

</mm:treenode>

<mm:treenode value="rootnode2" state="expanded">

<mm:treenode value="node2" state="expanded"></mm:treenode>

<mm:treenode value="node4" state="expanded"></mm:treenode>

</mm:treenode>

</mm:treecontrol>

Manipulating content within a tree control

Tree controls and the nodes within them are implemented as HTML tags. They are parsed by

Dreamweaver and stored in the document tree. These tags can be manipulated in the same

way as any other document node. For more information on

DOM functions and methods, see

Chapter 5, “The Dreamweaver Document Object Model,” on page 127.

Adding nodes To add a node to an existing tree control programmatically, set the

innerHTML property of the MM:TREECONTROL tag or one of the existing MM:TREENODE tags.

Setting the

inner HTML property of a tree node creates a nested node.
