ok, I have this simple select2 which needs tagging support.
My code :-

```
<select name="x1" id="x1" style="width: 20%">
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
</select>

```

JS :-

```
$(document).ready(function(){
    $("#x1").select2({
        tags: true
    });
});

```

My select2 should have tagging support, but it doesn't happen with my code. What wrong am I doing?
