Hello,
I have been studying the ways of storing hierarchical data in database, and i'm currently experiementing with the "Modified Preorder Tree Traversal" method to build a dynamic menu management system.
My question arises when having to re-order the menu structure in any desired fashion.
How is it possible in the aspects of re-calculating the left and right values...has anyone seen anymore in-depth tuts on this method of sotring data?
