How to fix 'onClick to show content' : I have simple side navigation on my webpage, and have little problem i think with javascript code. What i need? When user open that page and choose to see content from category of 'Audi' to show sub-category in this case to show ( audi a4 and audi a5). Now is set to opened so user don't need to click on category 'Audi' to see content.

    <h4>Side navigation</h4>
    <nav class="checklist side-nav-toggle ajax">
    <h5><a href="#" class="opened">Audi</h5>
    <ul class="scroll-list" style="display:block;">
    <li><a href="#" rel="nofollow">Audi A3</a></li>
    <li><a href="#" rel="nofollow">Audi A5</a></li>
    </ul>
    </nav>

If you need more information, please write me i will answer immediately. Thanks all, and sorry for my bad english.

Thanks all
