Hi R,
I am using select.list names=c("Ravi", "Raj","Shubha","Nivriti") select.list(names) provides a drop down to choose one of the 4 names. However I would like to know if it is possible to create a classification something like this select.list(names) should give Boys Ravi Raj Girls Shubha Nivriti I should be able to choose only one of the names. Any help would be appreciated.
