Actually I am currently working on project(educational website),in that for designing a home page(displayed after login)
I needed a directory like structure,for:
first the course of user must be displayed
then after selecting course,list of subjects for that course is displayed,
then after selecting particular subject,study materials of that subject is displayed
Don't have any idea, how to do it?
Any suggestion ,will be appreciated..
Some information of the project can be found
