hi.!!I have been developing an online enrolment system for a client in php...ive encountered a problem during the middle situation.The client added a situation that when the student click on the first year link, the subject of that year will just pop-up under the link.example:
When the user click first year, the filipino,math, and science will appear, and will dissapear when they click another link.
Please help i dont know how to do this.!
