Creating a CSS drop-down menu that opens both on click and hover for iOS devices

When using a CSS dropdown list that opens on hover, there may be compatibility issues with iOS devices like iPads or iPhones. Here is a rough jFiddle showcasing the problem:

http://jsfiddle.net/7vtWy/1/

The dropdown works perfectly on Android devices with Chrome, where clicking the main menu item displays the dropdown list. However, on iOS devices, this functionality does not work. Is there a way to modify it so that on mobile devices, the dropdown will appear when the main menu is clicked since hover is not supported?

HTML

<header>
<nav role="navigation" class="clearfix">
        <ul id="nav-site">
            <li>
                <span class="arrow">Shop</span>
                <div class="dropdown_1column">
                    <div class="mainbox clearfix">
                        <ul>
                            <li class="main-category"><a href="new-products/">New Arrivals</a></li>
                            <li class="main-category"><a href="gifts-under-100/">Gifts Under $100</a></li>
                            <li class="main-category"><a href="staff-favorites/">Staff Favorites</a></li>
                            <li class="main-category"><a href="made-in-the-usa/">Made in the USA</a></li>
                        </ul>
                    </div>
                </div>
            </li>
        </ul>
    </nav>

Answer №1

Instead of relying on the hover function, I have implemented jQuery to bind to the touchstart and touchend functions. Essentially, the hover effect that triggers the drop-down menu has been replaced with a class called "hover". When users interact with your navigation items on mobile devices, they will see the drop-down menu appear when touching the item and disappear when releasing their finger.

It's worth considering additional enhancements for a better user experience, such as adding a "click/tap to dismiss" feature or something similar.

If you plan to use this functionality on desktop browsers as well, you can utilize the mouseenter and mouseleave events, which also work in Mobile Safari according to reports.

Introducing the jQuery Code

$(function () {
    $('header nav li').bind({
        'touchstart': function () {
            $(this).addClass('hover')
        },
            'touchend': function () {
            $(this).removeClass('hover')
        }
    });
});
