I apologise in advance if this question should be in another forum but I've come to trust it here and I'm lost as to where to start to look with this one.
I want to build a catalogue, when I click the hyperlink to the catalogue page I want the catalogue to be organised/displayed in the same format as you view with windows explorer. IE One folder at the top with a little plus sign on the left, click the plus and opens up that folder. I would need to be able to provide functionality for a user to build their own catalogue structure and use their own folder names.
I saw it a few years ago on an online app so I know it can be done but I'm not sure where to start to look.
I know I can do it with js but that wasn't what I saw before and I want js disabled browsers to see it that way.
Hopefully I've explained things clear enough and any pointers as to how to go about making a start would be much appreciated.
Many thanks in advance O
