Hie,I had asked this question already but I have make it briefly now please share some logic. 1st dropdown List- Contain Class-1, class-2, class-3..etc. 2nd dropdown List- Depends on class.If we chose class-1 and class-2 then respective Student Id will show on 2nd dropdown list. I want selected Classes in respective variables and selected turbines in respective variable. Then I will get this selected variables and use in another page.

I want multiple selection in each dropdown list. suppose I have select one Class-1 then, On the classId second dropdown list will fill with respective studentID,again I am select another class-2 then again Add respective studentID list in 2nd dropdown list.

In my databse script ClassId and StudentId this attribute present in same table only (not diffrent tables).

Table view somewhat like this->

 ClassID    StudentID   StudentNm 
      1        101         abc 
      1        102         xyz 
      1        103         jkl 
      2        201         uio
      2        202         tyu 
      3        302         qwe 
      3        305         zxc
