How do I create checkboxes using Javascript?

Hi, I am trying to customize a form question to include different types of inputs (i.e., drop down, multiselection). I have figured out to create a multiselection that requires ctrl to be held, but find it is not very user friendly. What I really would like is to do is have several checkboxes. Here is my currently code for the multiselection box. Can you help me adjust to checkboxes? var element=' <select class="js-example-basic-multiple js-states form-control" id="id_label_multiple" multiple="multiple"><option value='Nobody'>Nobody</option><option value='Sibling'>Sibling</option><option value='Parent'>Parent</option><option value='Friend'>Friend</option></select>'; jQuery(element).insertAfter("#"+that+" .InputText:eq(3)"); jQuery("#s3").on('change',function(){ jQuery("#"+that+" .InputText:eq(2)").val(jQuery("#s3 option:selected").text()); }); Thanks, Andrew
