Ok I have a drop down menu that functions with some jquery but now I am trying to get it working with css in case users have js disabled. I have a selector with the hover pseudo-class and I am telling it to display:block the hidden submenu when moused over. But when I try to select any links in the sub-menu it promptly disappears once my cursor moves off the element I am assigning to the pseudo-class. sorry if my terminology is off I am new to this. Here is the pertinent code:

Code:
<nav>
      <ul id="ddmenu">
        <li><a href="index.html">Homepage</a></li>
        <li><a href="#">About</a>
          <ul>
            <li><a href="#">Our Mission</a></li>
            <li><a href="#">The Staff</a></li>
            <li><a href="#">History</a></li>
          </ul>
        </li>
        <li><a href="#">Services</a>
          <ul>
            <li><a href="#">Donations</a></li>
            <li><a href="#">Volunteering</a></li>
            <li><a href="#">Housing</a></li>
            </ul>
          </li>
        
        <li><a href="#">International</a>
          <ul>
            <li><a href="#">China</a></li>
            <li><a href="#">Japan</a></li>
            <li><a href="#">Canada</a></li>
            <li><a href="#">Australia</a></li>
            <li><a href="#">South America</a></li>
          </ul>
        </li>
        <li><a href="contact.php">Contact Us</a></li>
      </ul>
    </nav>
and here is my css:
Code:
 #ddmenu li { display: block; position: relative; float: left; font-size: 1.45em; text-shadow: 1px 1px 0 #fff; border-right: 1px solid #dae0e5; }

#ddmenu li a {
  display: block;
  float: left;
  padding: 0 12px;
  line-height: 78px;
  font-weight: bold;
  text-decoration: none;
  color: #FF0000;
  -webkit-transition: all 0.2s linear;
  -moz-transition: all 0.2s linear;
  -o-transition: all 0.2s linear;
  transition: all 0.2s linear;
}
#ddmenu li:hover > a { color: #565051; background: #C0C0C0; }


#ddmenu li:hover ul { display:  block;}

#ddmenu ul {
  position: absolute;
  top: 88px;
  width: 130px;
  background: #fff;
  display: none;
  margin: 0;
  padding: 7px 0;
  list-style: none;
  border-radius: 3px;
  border: 1px solid rgba(0, 0, 0, 0.2);
  box-shadow: 0 0 5px rgba(0, 0, 0, 0.2);
}

/* tooltip arrow */
#ddmenu ul:after {
  content: "";
  width: 0;
  height: 0;
  position: absolute;
  bottom: 100%;
  left: 8px;
  border-width: 0 8px 8px 8px;
  border-style: solid;
  border-color: #fff transparent; 
}

#ddmenu ul:before {
  content: "";
  width: 0;
  height: 0;
  position: absolute;
  bottom: 100%;
  left: 4px;
  border-width: 0 10px 10px 10px;
  border-style: solid;
  border-color: rgba(0, 0, 0, 0.1) transparent;  
}

#ddmenu ul li { 
  display: block; 
  width: 100%; 
  font-size: 0.9em; 
  text-shadow: 1px 1px 0 #fff;
}

#ddmenu ul li a {
  display: block;
  width: 100%;
  padding: 6px 7px;
  line-height: 1.4em;
  -webkit-transition: all 0.2s linear;
  -moz-transition: all 0.2s linear;
  -o-transition: all 0.2s linear;
  transition: all 0.2s linear;
}
#ddmenu ul li a:hover { background: #C0C0C0; }
