#   Name:    ddTree (DropDown Tree)
#   Version: 1.0.2
#            Bug fix by enidan: make depth parameter really optional, and also
#            make doc parameter become optional (defaults to 0)
#   Author:  Urique Dertlian ([email protected])
#   Date:    Feb 28, 2008
#   Using:   Create TV of kind "DropDown List Menu", feel elements field with string:
             @EVAL return $modx->runSnippet("ddTree",array('doc'=>0,'depth'=>0));
             
             Here 'doc' is identifier of parent document, children of which will be displayed in DropDown menu.
             Optional parameter 'depth' is used to limit depth of tree, for example, use 0 (zero) - if you want to display only first level of children.
             If depth parametr is not set, ddTree builds up to 100 levels.
