[jQuery] Hover delay possible without additional plugin?

[jQuery] Hover delay possible without additional plugin?


I've created a menu system simialr to the Brown.edu homepage except
I've done it without js due to target audience restrictions. I'd like
to have a hover delay so that when the user mouses over the link the
menu will display after a couple seconds. I'm interested in using
jquery and I spent the day looking around for a way to do it without
having to use any additional plugins. I know that superfish menu is an
option, but that would be too heavily js powered for this menus
purposes.
Additionally, the hover needs to be specified on the <a> tag, so that
the menu still works in IE regardless of js being on or off (if off,
the only thing missing would be the delay feature).
Is there a way to control delay using what is available in the jquery
library only? Thanks, c.s.
This is a sample of the wireframe code:
HTML:
<ul id="topmenu">
    <li><a href="">this is the main link</a>
        <ul class="tags">
            <form>
            <div>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
            </div>
            <div>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
            </div>
            <div>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
                <li><input type="checkbox">hello</li>
            </div>
            </form>
        </ul>
    </li>
    <li><a href="">this is the main link</a>
        <ul>
            <form>
                <li><input type="checkbox">hello</li>
            </form>
        </ul>
    </li>
    <li><a href="">this is the main link</a>
        <ul>
            <form>
                <li><input type="checkbox">hello</li>
            </form>
        </ul>
    </li>
</ul>
