what i am trying to do is a user is searching for a key work in wiki function () which returns a list of possible option and from the client select the relevant option

AddtoPanle(url,title)
{
var wl =document.getElementById('divWikis');

var link;
link = document.createElement('Option');
link.text=title;
link.value = href;
wl.add(link);
