I have a dropdown as seen below:

```
<select id="models" onchange="removeElements()">
            <option id = "remove" value="0">R8</option>
            <option id = "remove" value="1">Quattro</option>
            <option id = "remove" value="2">A6 hatchback</option>
</select>

```

How would I create the script `removeElements()` that would remove all of the options within the select?
