CSS for sub-menu on navigation bar not working

Question

I am working on a site and have created a navigation bar with sub-items but I am not getting these sub-items display on hover. Here's my HTML and CSS code for the navigation bar:

 <div class="collapse navbar-collapse" id="spi-primary-nav">
      <ul class="nav navbar-nav">
         <li id="menu-item-9265" class="home-link menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-9001 current_page_item menu-item-9265">
             <a href="index.html">Home</a>
         </li>
         <li id="menu-item-9004" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-9004 ">
             <a href="Default.aspx">Store</a>
             <ul>
                  <li><a href="#">Sub Menu 1</a></li>
                  <li><a href="#">Sub Menu 2</a></li>
                  <li><a href="#">Sub Menu 3</a></li>
             </ul>
         </li>      
     </ul>
</div> 

The CSS is here:

.navbar-nav > li > ul {
    display: none;
    position: absolute;
}
.navbar-nav > li > ul:hover {
    display:block;
}

Here is the live link of the site in case someone wants to inspect the elements using Firebug: http://webcalendar.pcprosinc.com/Home

Please help me out

Answer 1

You got your :hover in the wrong place.
It should be in the li instead of the ul

Try this instead:

.navbar-nav > li:hover > ul {
    display:block;
}
