Hi David, Thank you for your response. But that wasn't what I was looking for. names=c("Ravi", "Raj","Shubha","Nivriti") select.list(names) gives a pop up with the 4 names. I just wanted in the pop up a heading (say BOYS) followed by two names and another heading (say GIRLS) and the remaining two names.
Is there a way I can include headings in the select.list() Thank you once again for the help.
