showlist:function() {
            return this.trigger("showlist");
        },

        }).bind("showlist", function() {
                   showalldatafromarray ...
        });

this works for showing an alert
.NET Code
$("#<%=txtJobs.ClientID %>").showlist();

however I cannot work out where the call to show the list full of the entire Json array can be activated, could someone help me add this function in please. Need to have the ability for the autocomplete box to work like a drop down list, whilst still having the autocomplete functionality, have had a look at the sexy combo plugin but that too will also require some modification, and already have this setup.
