Danke Felix! The thing is: I don't understand it. The rdoc is a bit more extensive on this and I think I get the syntax of nested_set_options, but I don't understand how to really use this in my view. Should I still send the self_and_descendants object from my controller and how can I use this to generate lists within lists (<ul> within <li>)? The usage with '-' * i.level is very ugly and totally unsuitable in my case. I want a parent to put an <ul> around its children and every child within an <li> tag. But the nested_set_options method doesn't seem to be able to work this way. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
