[Zope] Tree from a dictionary

Dear Sir, Madam, I have an external method that returns a nested dictionary. for example: {'page_one':{'subpage':'contentstring'},'page_two':'contentstring'} I want this dictionary displayed into a tree strucure Where the nested dictionaries appear as branches of the tree Is there some documentation that explains how to do it? Is it already discussed in the community section of Zope??? Wim Vanroose
