Trying to use Select2

[Vanilson Lourenço]

hi, I´m trying to use Select2, specifically that one that looks like a 
normal but isn´t working. 
Select2 site: http://ivaynberg.github.com/select2/
Code:

js

        $(document).ready(function () {
            $('select[name=docs]').select2({
                allowClear: true
            });
        });

html

<select name = "docs">
                                        <option value="AL">Alabama</option>
                                        <option value="WY">Wyoming</option>
                                    </select>
