I haven't done a lot of work with multi-level, pure CSS drop-down menus before, but I'm now looking for the cleanest possible method that is out there. When I've searched for this online I've found a lot of solutions that were 4-5 years old and I'm not sure whether there are better ways to achieve this than to do something like this.

    display: inline;
}


/* Menu Link Styles */

.top-level-menu a /* Apply to all links inside the multi-level menu */
{
    font: bold 14px Arial, Helvetica, sans-serif;
    color: #FFFFFF;
    text-decoration: none;
    padding: 0 0 0 10px;

    /* Make the link cover the entire list item-container */
    display: block;
    line-height: 30px;
}
.top-level-menu a:hover { color: #000000; }
<ul class="top-level-menu">

        </ul>
    </li>
    <li><a href="#">Contact</a></li>
</ul>

For a menu which responds to click events as opposed to just hover, and acts in a similar way to a select control...

Pure CSS Select Menu

HTML

<ul tabindex='0'>
    <li>
        <input id='item1' type='radio' name='item' checked='true' />
        <label for='item1'>Item 1</label>
    </li>
    <li>
        <input id='item2' type='radio' name='item' />
        <label for='item2'>Item 2</label>
    </li>
    <li>
        <input id='item3' type='radio' name='item' />
        <label for='item3'>Item 3</label>
    </li>
</ul>

CSS

ul, li {
    list-style:none;
    margin:0;
    padding:0;
}
li input {
    display:none;
}
ul:not(:focus) input:not(:checked), ul:not(:focus) input:not(:checked) + label {
    display:none;
}
input:checked+label {
    color:red;
}
