anbutechie has asked for the wisdom of the Perl Monks concerning the following question:

hi,

I m using CGI module. I created 2 list boxes with 2 values in first and 4 values in second, I m showing all 6 values (2+4) on load. On selecting first value of first list box, first two values of sencond list box should alone be listed and on selecting both values in first list box all the 4 values should be displayed in 2 nd list box. How is it possible

Regards,
Anbarasu

    You'll have to use JavaScript and modify the second listbox (accessing it via the DOM) when an onChange event occurs in the first.

    That seems impossible
