Answer 2

If you are new to web development I'd recommend you to use jquery and jqueryUI package. The link above is to demo page where you can play with different types of datasources. I've copied an example which uses simple array as a datasource

<script>
    $(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
        });
    });
    </script>

<div><input class="tags" type="text" /></div>
<div><input class="tags" type="text" /></div>

The AutoSuggest plugin has been deprecated and is now included in jQuery UI.
