Over Ride Return False.

Over Ride Return False.

I would like to code a drop down navigation where the top tier of navigation links is NOT clickable, only the child elements. I am wondering how I would go about coding this using Jquery.

Here is my code so far.

$("#menu ul li").click(function(event) {
    $(this).find('ul').css('display','block');
            return false;
});   

$("#menu ul li ul li").click(function() {
            return true;
});   

The reason this doesn't work is because it makes ALL the links "return false". The second function doesn't over ride the first one. What do I replace it with in order to make the ul li ul li links direct the browser to their URL when clicked?

Thanks in advance for any help!

Cheers,
Matt
