Answer 1

Your issue here is that your radio button change events are overlapping each other so they don't have scope they just override each other, see the changes below where the radio input are now wrapped in a container and each event is scoped separately.

it's worth noting that using scope around each section of dropdown and radio button set you could refactor your code into a single function can handle all events.

 (function() { var options = $("#DropDownList2").html(); $('#DropDownList2 :not([value^="Fac"])').remove(); $('.group1 input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList2").html(options); $('#DropDownList2 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })(); (function() { var options = $("#DropDownList3").html(); $('#DropDownList3 :not([value^="Dip"])').remove(); $('.group2 input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList3").html(options); $('#DropDownList3 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })(); (function() { var options = $("#DropDownList4").html(); $('#DropDownList4 :not([value^="Dr"])').remove(); $('.group3 input:radio').change(function(e) { var text = $(this).val(); $("#DropDownList4").html(options); $('#DropDownList4 :not([value^="' + text.substr(0, 3) + '"])').remove(); }); })();
