<input type="radio" id="electronics" name="rdbutton" />
<label for="computers">Computers</label>
<input type="radio" id="computers" name="rdbutton" />
<label for="others">Others</label>
<input type="radio" id="others" name="rdbutton" />
<input type="text" id="others-text" name="others-text" class="hidden" />

$(function() {
    $('input[type="radio"]').click(function() {
        if($(this).attr('id') == 'others') {
            $('#others-text').removeClass('hidden');
        } else {
