jquery: mouseout applies to nested elements

问题

ul with links nested in a div layer. mouse pointer goes over .title, ul is shown.

the problem: mouseout() applies to nested elements

mouseout() is for the div

<div>
  <a class="title">Section A</a>
     <ul>
        <li><a href=''>link 1</a></li>
        <li><a href=''>link 2</a></li>
        <li><a href=''>link 3</a></li>
     </ul> 
</div>

$('.title').mouseover(function() {
   $('ul').slideDown();
})

$('div').mouseout(function(){
   $('ul').slideUp();
});
