Jquery - Optgroup element
i want to use optgroup for mobile view of my website. following is my optgroup options. 

HTML:

    <select name="select-choice-8" id="select-choice-nc">
            <optgroup label="News">
                <option value="feature">Fea</option>
                <option value="current">Current</option>
                <option value="research">Research</option>
            </optgroup>
            
            <optgroup label="Archive">
                <option value="archive">Archive</option>
            </optgroup>
           
            <optgroup label="Video">
                <option value="">Video</option>
            </optgroup>
            
            <optgroup label="Submit">
                <option value="">Story</option>
                <option value="">Event</option>
            </optgroup>
        </select>



i want write javascript (use jquery)and, and want to do some ajax calls base on the user selection in order to avoid reloading the whole page (for e.g. using AJAX container content) to display content. 

Need some idea or examples to solve this problem
Thanks,
