jquery - Jquery validation of a select box

Question

I'd would like to use the jquery validation plugin to validate and ensure that the user selects an option. I know that it's working if you leave the first option value blank like this :

<select id="jungle" name="jungle" title="Please select something!" validate="required:true">
        <option value=""></option>
        <option value="1">Buga</option>
        <option value="2">Baga</option>
        <option value="3">Oi</option>
    </select>

But I need a solution where I can have the value of the first option not blank as it needs to be filled dynamically. e.g.

<select id="jungle" name="jungle" title="Please select something!" validate="required:true">
    <option value="default"></option>
    <option value="1">Buga</option>
    <option value="2">Baga</option>
    <option value="3">Oi</option>
</select>

Does anybody knows how to customize the default validation to have this working ?
