You can do the restriction in your SQL query.  Use 'TOP 5'.  You will probably want to have some kind of ORDER BY OR WHERE clause criteria so you can properly identify what records are the top 5.

SELECT TOP 5 MyField
From MyDatabase
WHERE ...
ORDER BY ...

To accomplish this, you can use a hidden field that tracks the number of selections, and display a message when it reaches 5.

Here is a Fiddle Demo.

Given the following HTML

<div class="ui-widget">
  <label for="tags">Tags: </label>
  <input id="tags">
</div>
<input type="hidden" id="hCount" value="0">
<span id="msg"></span>

Open in new window


The jQuery looks like:

  $(function() {
    var availableTags = [
      "ActionScript",
      "AppleScript",
      "Asp",
      "BASIC",
      "C",
      "C++",
      "Clojure",
      "COBOL",
      "ColdFusion",
      "Erlang",
      "Fortran",
      "Groovy",
      "Haskell",
      "Java",
      "JavaScript",
      "Lisp",
      "Perl",
      "PHP",
      "Python",
      "Ruby",
      "Scala",
      "Scheme"
    ];
    $("#tags").autocomplete({
      source: availableTags,
      select: function(event, ui) {
        var num = parseInt($('#hCount').val());
        $('#hCount').val(num + 1);
        if ((num + 1) === 5) {
          $('#msg').text('You have selected 5');
        }
      }
    });
  });
