Hello Everone, 

I created the code below, however, I believe I should use something like an array because when I call the function several times, then it's appending the same name(xnome) and id.

2.     //EXAMS
3.     $('#idexame').change(function () {
4.       
5.       var doc = document.getElementById("idexame");
6.       
7.       $("#xnome").html(doc.options[doc.selectedIndex].text);
8.       
9.        $(".selecionado").append('<div class="alert alert-warning alert-dismissible">
10.       <button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
11.       <h4 id="xnome">'+doc.options[doc.selectedIndex].text+'</h4>
12.       <textarea name="sexames[]" class="form-control" rows="2" placeholder="Observação ..."></textarea>
13.       </div>
14.       <input type="hidden" name="exameid[]" value="'+doc.options[doc.selectedIndex].value +'"></input');
15.     });
