I stucked in a Problem When Playing with Drop Downs.I tried to use this http://www.grocerycrud.com/forums/topic/1087-updated-24112012-dependent-dropdown-library/
But actually my requirement is quite different. I have a table fwld_products in which i am adding all other table's categories, from
fwld_cat_main (main Category's ID),
fwld_cat_sub1 (sub1 Category's id)
fwld_cat_sub2 (sub2 Category's id)
fwld_cat_sub3 (sub3 Category's id)
I want to Display Dropdown in such a way, when user Selects main Category, the Drop Down Appear (sub1) Having Data related to main category and when sub1 selected drop down appear (sub2) showing data related to sub1, and sub2 selected and drop down appear(sub3) to show data related to Drop down (sub2).
When submitted Finnally data inserted to [fwld_products].
