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 “The
Dreamweaver Document Object Model” on page 41.
