HI dependent drop down is not working after referencing!! and imagine
every column is dependent on each other like roll no is dependent on
name &class dependent on roll no and subjects dependent on class.
For example consider an app called school there are two tables BASIC
INFORMATION & ACADEMICS in basic information columns be like NAME ROLL
NO in ACADEMICS columns be like CLASS SUBJECTS and i want dependent drop
down for NAME, ROLL NO, CLASS, SUBJEC...
