How to keep drop-down style menus visible without needing to hover over them

I came across a tutorial on creating drop-down menus, and it mentioned that the drop-down menus should remain visible even after you stop hovering over the main menu item. However, in my case, the menu disappears completely, making it difficult to select any items!

Specifically, the issue seems to be with the Music menu section where the drop-down (or "drop-right") menu is located.

Here's the link to the Fiddle for reference: http://jsfiddle.net/Gb2aS/

Here's the code snippet:

HTML:

<!DOCTYPE HTML>
<html>
<head>
    <link href="stylesheet.css" rel="stylesheet" type="text/css">
    <title>Home</title>
</head>
<body>
    <div ID="menubox">
        <ul>
        <li><a href="http://folk.ntnu.no/arnstekl/" class="link">Home</a></li>
        <li><a href="#" class="link">Music</a>
            <ul>
                <li><a href="https://soundcloud.com/arnsteinkleven/" class="link">My music</a></li>
                <li><a href="http://folk.ntnu.no/arnstekl/gilberto.html" class="link">The Joao Gilberto project</a></li>
           </ul></li>
        <li><a href="https://www.github.com/arnstein" class="link">Github</a></li>

        <li><a href="http://www.flickr.com/photos/92472314@N03/" class="link">Pictures</a></li>

        </ul>

    </div>
    <div ID="circle">
        <p ID="title"> A <br> r <br> n <br> s <br> t <br> e <br> i <br> n </p>
    </div>
    </body>
</HTML>

CSS:

#menubox
{
    width: 8%;
    height: 30%;
    border: 10% solid #C7D93D;
    border-radius: 5%;
    position: fixed;
    margin-top: 12%;
    margin-left: 18%;
    font-family: Ubuntu, Lucida console, Futura;
    list-style: none;
    float: left;
}

... (CSS code continued)

.link
{
    text-color: #FFF0A5;
    text-decoration: none;
    text-align: left;
}

Answer №1

The issue arises due to the offset of your sub list, creating deadspace that the cursor must traverse from the main menu item to the submenu. To resolve this problem, you can implement the following code:

#menubox ul li:hover ul
{
    left: 0;
    top: 0;
    z-index:100;
}

As elaborated by Daniel Gimenez earlier, the reason behind the persistent visibility of the submenu is its association as a child of the main ul item. As long as the cursor remains over the submenu, the browser considers it to still be hovering over the original menu item, thereby maintaining the :hover css effect.

This mechanism functions effectively for dropdown/popout menus, since despite the physical display of the child object outside its parent, it is conceptually "inside" the parent in terms of code. However, if there exists a physical gap between them and the cursor crosses that gap, the :hover rule is deactivated causing the submenu to disappear.

Answer №2

After carefully reviewing your CSS, I have simplified it to address the issue of a gap between your main link and submenu.

To explain the changes made in the CSS: * Anchors now have a block inline-block type with the exact width of the parent li and ul. * Submenus are contained within li elements, making them visible when li elements are hovered over. The submenu remains visible because it is a child of the li element. * By setting the anchors to 100% width and stretching the li elements, they now abut the submenu. This eliminates any gap when moving the mouse over, ensuring that the submenu stays visible.

#menubox { 
    position: absolute;
    left: 100px;
    top: 100px;
}

#menubox ul {
    display:inline-block;
    padding-left:0;
}

#menubox > ul {
    width: 100px;
}

#menubox > ul ul {
    position:absolute;
    display: none;
    width: 200px;
}

#menubox li {
    list-style-type:none;
    display:block;
}

#menubox li:hover {
    background:red;
}

#menubox a {
    display:inline-block;
    width:100%;
}

#menubox ul li:hover ul {
    display: inline-block;
    background: orange;
}

Answer №3

To ensure the list remains visible, I enhanced it by adding padding to create a surrounding block. This prevents the list from disappearing when your mouse hovers over it.

http://example.com/jsfiddle-link

#menubox ul ul
{
    position: absolute;
    left: -9999px;
    padding: 100px;
    list-style: none;
}

One issue to address is the drawn circle overlaying the list. Take some time to resolve this layout concern.

I do appreciate Daniel's solution as an improvement. Assigning individual classes to links offers a more efficient approach. Consider his method and modify it according to your requirements.
