Using RadioButton in Perl/Tk

Hi,

I have created a GUI using Perl/Tk....In that I have a Radio Button with 3 option....op1...op2....op3
Now if user select op3....user must have to enter couple of entries below that. Thats not the case for op1...op2...

currently I put a note that if user select op3....they have to enter in below entries...
Is there something I can do...so that If user select op3...then and then only the entries below it...can be displayed...otherwise don't display the entries below it.

Please advise...

usually, you don't want the entries to appear/disappear, but instead become enabled/disabled.

But, if you want to have them appear/disappear,
$widget->packForget();    #to remove
$widget->pack();              #to add


To enable/disable
$widget->configure(-state=>'normal');    #to enable
$widget->configure(-state=>'disabled');  #to disable
