Radio button question

[SeenGee]

Is it possible to have a radio button option in a form that gives the user the chance to enter a response in a text area, for instance with a radio button with the option of 'Other' that when selected provides a textarea to write in but disables the other radio's?

with Jscript maybe... otherwise just have PHP parse the variables when its submitted, if OTHER is selected ignore the other options and include the $textarea data also
