Unable to choose an option from the panel

I am currently working on a menu and panel setup (you can view the demo here: http://jsfiddle.net/vals/j2LrQ/1/). The visibility of the panel depends on the selected item from the menu. However, I am facing an issue where the panel disappears when I move my mouse over it, making it impossible to select a value. I would like to find a way to make the background color of the menu cover the entire screen as well.

body {
    font: 10px normal Verdana, Arial, Helvetica, sans-serif;
    margin: 10px auto;
    padding: 0;  
}
.container {
    float:left;
    width:100%;
    background:#113388;
    margin: 0 auto;
}

ul#topnav {
   margin: 0; padding: 0;
   float: left;
   list-style: none;
   font-size: 1.2em;
   background: #113388;
   position:relative;
   left:30%;
   text-align:center;
}
ul#topnav li {
   float: left;
   margin: 0; padding: 0;
   border-right: 1px solid #555;
   right:30%;
}
ul#topnav li a {
   padding: 10px 15px;
   display: block;
   color: #f0f0f0;
   text-decoration: none;
   text-align:center;
}

ul#topnav li span {
    padding: 15px 0;
    position: absolute;
                left: 0; top:60px;
                display: none;
                text-align:Center;
                width: 100%;
                background: #558ED5;
                color: #fff;
                -moz-border-radius: 0 0 5px 5px;
                -webkit-border-radius: 0 0 5px 5px;
            }
ul#topnav li:hover span { display: block; }
ul#topnav li span a { display: inline; }
ul#topnav li span a:hover {text-decoration: underline;}

When using a drop-down menu, you activate it by hovering over a button to trigger an action. If there is any white space between the button and the menu, the action will be cancelled when moving away from it. This means that the intended functionality cannot be achieved in practice. The provided solutions offer the best alternatives, unless opting for a workaround. If Solution 1 does not suffice, proceed to Solution 2.

Solution 1

To resolve the issue, eliminate the gap between the main navigation bar and the secondary level navigation bar. Adjustments such as removing float lefts, changing percentages, and using display inline-block to fix the width problem can help:

    body {
    font: 10px normal Verdana, Arial, Helvetica, sans-serif;
    margin: 10px auto;
    padding: 0;  
}
.container {
    float:left;
    width:100%;
    background:#113388;
    margin: 0 auto;
}

ul#topnav {
   margin: 0; padding: 0;

   list-style: none;
   font-size: 1.2em;
   background: #113388;
   position:relative;
   text-align:center;
}
ul#topnav li {
   display: inline-block;
   margin: 0; padding: 0;
   border-right: 1px solid #555;

}
ul#topnav li a {
   padding: 10px 15px;
   display: block;
   color: #f0f0f0;
   text-decoration: none;
   text-align:center;

}

ul#topnav li span {
    padding: 15px 0;
    position: absolute;
                left: 0; top: 100%;
                display: none;
                text-align:Center;
                width: 100%;
                background: #558ED5;
                color: #fff;
                -moz-border-radius: 0 0 5px 5px;
                -webkit-border-radius: 0 0 5px 5px;
            }
ul#topnav li:hover span { display: block;}
ul#topnav li span a { display: inline;  }
ul#topnav li span a:hover {text-decoration: underline; }

Solution 2

If your buttons are images created in software like Photoshop or GIMP, you can create the illusion of white space below them by doubling up on white space. This visual trickery can mimic the appearance of white space between the first and second-level nav bars.

To achieve the desired effect, a small modification in our HTML code is all that's needed:

<div class="container">
    <ul id="topnav">
        <li ><a href="#">Home</a></li>
        <li><a href="#">About</a></li>
        <li><a href="#">Services</a>
                <div class="wrapper">
                    <div class="sec-nav">
                    <a href="#">What We Do</a>
                    <a href="#">Our Process</a>
                    <a href="#">Testimonials</a>
                    </div>
                </div>
        </li>
        <li><a href="#">Portfolio</a>
            <div class="wrapper">
                <div class="sec-nav">
                <a href="#">Web Design</a>
                <a href="#">Analytics</a> |
                <a href="#">Database Design</a>
                </div>
            </div>
        </li>
        <li><a href="#">Contact</a></li>
     </ul>
</div>

A simple addition of a div.wrapper around the link block will do the trick.

For styling, make the following adjustments in the CSS:

ul#topnav li div.wrapper {
    padding-top: 40px; /* controls the gap between the menus */
    position: absolute;
    left: 0; 
    top: 33px; /* Add just enough height to clear the text links in top nav */
    display: none;
    text-align:Center;
    width: 100%;
    color: #fff;
    -moz-border-radius: 0 0 5px 5px;
    -webkit-border-radius: 0 0 5px 5px;
}
ul#topnav li:hover div.wrapper { 
    display: block; 
    background-color: yellow; /* to show the spacing created by the wrapper */
}
ul#topnav li div.sec-nav {
    background: #558ED5;
}
ul#topnav li div.sec-nav a {
    display: inline-block; 
}
ul#topnav li a:hover {text-decoration: underline;}

View the demo here: http://jsfiddle.net/audetwebdesign/cjTym

Explanation

The adjustment of the top property for div.wrapper ensures it slightly overlaps the top navigation to maintain focus when moving the mouse.

Adding top padding in div.wrapper creates space between the two menus.

Lastly, applying a background color to the .sec-nav block enhances the look of the links.

Note

In this setup, I opted for <div> instead of <span> to wrap the links. Alternatively, using a span with display type set to block can also work.
