How do I get this drop down menu to actually "drop down" - html

Question

This navigation bar I made has drop down menus on certain buttons. I want to make it so when the button that activates the drop down menu is hovered over, the drop down menu sort of falls down into place like this: http://designmodo.com/demo/css3dropdownmenu/
Here's the link to my code: http://jsfiddle.net/w5Ce7/2/
Here's the code just pasted on here:
HTML
<div id="container">
<div id="navbar">
<ul>
<li>Home</li>
<li>Questions</li>
<li>Classes</li>

<li>Cakes

</ul>

Answer 1

There you go. FIDDLE. The problem was displaying sub ul's as block.
#navbar ul li:hover > ul {
opacity:1;
height:auto !Important;
}
#navbar ul li:hover > ul > li {
height:50px !important;
opacity:1;
}
#navbar ul {
background: #efefef;
background: linear-gradient(top, #efefef 0%, #bbbbbb 100%);
background: moz-linear-gradient(top, #efefef 0%, #bbbbbb 100%);
background: webkit-linear-gradient(top, #efefef 0%, #bbbbbb 100%);
box-shadow: 0px 0px 9px rgba(0, 0, 0, 0.15);
padding: 0 40px;
border-radius:10px;
-moz-border-radius:10px;
-webkit-border-radius:10px;
list-style:none;
position:relative;
display:inline-table;
}
#navbar ul:after {
