Question

I need to show user all autocomplete choices, no matter what text he already wrote in the field? Maybe i need some other plugin?

$('#addressSearch').autocomplete("search", "");

That doesn’t work.

There are two scenarios:

1. You’re using a local data source. This is easy to accomplish in that case:

   var src = ['JavaScript', 'C++', 'C#', 'Java', 'COBOL'];
   $("#auto").autocomplete({
       source: function (request, response) {
           response(src);
       }
   });
   

2. You’re using a remote data source.

   $("#auto").autocomplete({
       source: function (request, response) {
           // Make AJAX call, but don't filter the results on the server.
           $.get("/foo", function (results) {
               response(results);
           });
       }
   });
   

Either way you need to pass a function to the source argument and avoid filtering the results.
