[Zope-dev] Problem with directories

Hi, I want to create folder everywhere. So, I've built a tree that display a part of a directory. In that directory, I want my guest to create folder as deep as they can build. but, I can't : I'm limited to create folder in the directory where I am. I know that I should use the <dtml-with> tag ; but I can't dynamically build chained dtml-with tag. If anybody could help me.... thaks in advance...
