I have three drop-down boxes just like ex:
1. class list (ClassI, ClassII...) 2. subject list (Hindi, English...) 3. chapter list (H-ChapterI, H-ChapterII, E-ChapterI, E-ChapterII...)
When a user clicks on class list drop-down, there will be two option (ClassI, ClassII and so on...). When I select ClassI in a subject list (Hindi, English and so on...) will become as same. When I select on Hindi in chapter list related to Hindi (HChapterI, HChapterII) all chapter will come. This is what I want in my view filter.
